SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-75479; File No. SR-EDGX-2015-33]


Self-Regulatory Organizations; EDGX Exchange, Inc.; Notice of 
Filing and Immediate Effectiveness of a Proposed Rule Change to Rules 
11.6, 11.8, 11.9, 11.10 and 11.11 to Align With Similar Rules of the 
BATS Exchange, Inc.

July 17, 2015.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given 
that on July 8, 2015, EDGX Exchange, Inc. (the ``Exchange'' or 
``EDGX'') filed with the Securities and Exchange Commission 
(``Commission'') the proposed rule change as described in Items I and 
II below, which Items have been prepared by the Exchange. The Exchange 
has designated this proposal as a ``non-controversial'' proposed rule 
change pursuant to Section 19(b)(3)(A) of the Act \3\ and Rule 19b-

---------------------------------------------------------------------------

I. Self-Regulatory Organization's Statement of the Terms of Substance 
of the Proposed Rule Change

    The Exchange filed a proposal to amend certain rules to better 
align Exchange rules and system functionality with that currently 
offered by BATS Exchange, Inc. (``BZX''). These changes are described 
in detail below and include amending: (i) Rule 11.6, Definitions; (ii) 
Rule 11.8, Order Types; (iii) Rule 11.9, Priority of Orders; (iv) Rule 
11.10, Order Execution; and (v) Rule 11.11, Routing to Away Trading 
Centers. The Exchange does not propose to implement new or unique 
functionality that has not been previously filed with the Commission or 
is not available on BZX. The Exchange notes that the proposed rule text 
is based on BZX rules and is different only to the extent necessary to 
conform to the Exchange's current rules.
    The text of the proposed rule change is available at the Exchange's 
Web site at www.batstrading.com, at the principal office of the 
Exchange, and at the Commission's Public Reference Room.

II. Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the Exchange included statements 
concerning the purpose of and basis for the proposed rule change and 
discussed any comments it received on the proposed rule change. The 
text of these statements may be examined at the places specified in 
Item IV below. The Exchange has prepared summaries, set forth in 
Sections A, B, and C below, of the most significant parts of such 
statements.

(A) Self-Regulatory Organization's Statement of the Purpose of, and 
Statutory Basis for, the Proposed Rule Change

1. Purpose
    In early 2014, the Exchange and its affiliate, EDGA Exchange, Inc. 
(``EDGA'') received approval to effect a merger (the ``Merger'') of the 
Exchange's parent company, Direct Edge Holdings LLC, with BATS Global 
Markets, Inc., the parent of BZX and the BATS Y-Exchange, Inc. 
(``BYX'', together with BZX, EDGA and EDGX, the ``BGM Affiliated 
Exchanges'').\5\ In order to provide consistent rules and system 
functionality amongst the Exchange and BZX, the Exchange proposes to 
amend: (i) Rule 11.6, Definitions; (ii) Rule 11.8, Order Types; (iii) 
Rule 11.9, Priority of Orders; (iv) Rule 11.10, Order Execution; and 
(v) Rule 11.11, Routing to Away Trading Centers.
---------------------------------------------------------------------------

    \5\ See Securities Exchange Act Release No. 71449 (January 30, 
2014), 79 FR 6961 (February 5, 2014) (SR-EDGX-2013-43; SR-EDGA-2013-
34).
---------------------------------------------------------------------------

    The proposed amendments are intended to better align certain 
Exchange rules and system functionality with that currently offered by 
BZX in order to provide a consistent functionality across the Exchange 
and BZX. Consistent functionality between the Exchange and BZX is 
designed to

[[Page 43811]]

reduce complexity and streamline duplicative functionality, thereby 
resulting in simpler technology implementation, changes and maintenance 
by Users \6\ of the Exchange that are also participants on BZX. Unless 
otherwise noted, the proposed rule text is based on BZX rules and is 
different only to the extent necessary to conform to the Exchange's 
current rules.\7\ The proposed amendments do not propose to implement 
new or unique functionality that has not been previously filed with the 
Commission or is not available on BZX.
---------------------------------------------------------------------------

    \6\ The term ``User'' is defined as ``any Member or Sponsored 
Participant who is authorized to obtain access to the System 
pursuant to Rule 11.3.'' See Exchange Rule 1.5(ee).
    \7\ To the extent a proposed rule change is based on an existing 
BATS Rule, the language of the BATS and Exchange Rules may differ to 
extent necessary to conform with existing Exchange rule text or to 
account for details or descriptions included in the Exchange Rules 
but not currently included in BATS rules based on the current 
structure of such rules.
---------------------------------------------------------------------------

Rule 11.6, Definitions
    Rule 11.6, Definitions, sets forth in one rule current defined 
terms and order instructions that are utilized in Chapter XI. Rule 11.6 
also includes additional defined terms and instructions to aid in 
describing System \8\ functionality and the operation of the Exchange's 
order types. The Exchange proposes to amend Rule 11.6 to align certain 
sections with BZX functionality and rules, including additional 
specificity regarding the operation of Exchange functionality. These 
changes are described below and include: (i) Amending paragraph (d) 
regarding Discretionary Range; (ii) deleting subparagraph (j)(3) 
regarding the re-pricing of orders with a Pegged instruction priced 
more aggressively than the midpoint of the national best bid or offer 
(``NBBO''); (iii) amending subparagraph (l)(1)(A) regarding the Price 
Adjust Re-Pricing instruction; (iv) amending subparagraph (l)(1)(B) to 
replace the Hide Not Slide Re-Pricing instruction with a Display-Price 
Sliding instruction; (v) amending subparagraph (l)(2) regarding the 
Short Sale re-pricing instruction; (vi) amending subparagraph (l)(3) 
regarding the re-pricing of non-displayed orders and orders with an Odd 
Lot \9\ size priced better than the NBBO; (vii) amending subparagraph 
(n)(1), (2) and (4) regarding the Aggressive, Super Aggressive, and 
Post Only instructions; and (viii) amending subparagraph (q) regarding 
Immediate-or-Cancel and Fill-or-Kill Time-In-Force instructions. As 
stated above, the proposed amendments to Rule 11.6 do not propose to 
implement new or unique functionality that has not been previously 
filed with the Commission or is not available on BZX. Each of these 
amendments are described in more detail below.
---------------------------------------------------------------------------

    \8\ The term ``System'' is defined as ``the electronic 
communications and trading facility designated by the Board through 
which securities orders of Users are consolidated for ranking, 
execution and, when applicable, routing away.'' See Exchange Rule 
1.5(cc).
    \9\ An ``Odd Lot'' is defined as ``any amount less than a Round 
Lot.'' See Exchange Rule 11.8(s)(2).
---------------------------------------------------------------------------

Discretionary Range (Rule 11.6(d))
    Current Functionality. Pursuant to current Rule 11.6(d), 
Discretionary Range is an instruction the User may attach to an order 
to buy (sell) a stated amount of a security at a specified, displayed 
price with discretion to execute up (down) to a specified, non-
displayed price. An order with a Discretionary Range instruction 
resting on the EDGX Book \10\ will execute at its least aggressive 
price when matched for execution against an incoming order that also 
contains a Discretionary Range instruction, as permitted by the terms 
of both the incoming and resting order.
---------------------------------------------------------------------------

    \10\ The ``EDGX Book'' is defined as ``System's electronic file 
of orders.'' See Exchange Rule 1.5(d).
---------------------------------------------------------------------------

    Proposed Functionality. The Exchange proposes to amend the 
Discretionary Range instruction under Rule 11.6(d) to align with BZX 
Rule 11.9(c)(10).\11\ As proposed, amended Rule 11.6(d) are 
substantially similar to BZX Rule 11.9(c)(10). To the extent the 
amended text of Exchange Rule 11.6(d) differs from BZX Rule 
11.9(c)(10), such differences are necessary to conform the rule to 
existing rule text.
---------------------------------------------------------------------------

    \11\ See Securities Exchange Act Release No. 74738 (April 16, 
2015), 80 FR 22600 (April 22, 2015) (SR-BATS-2015-09) (Order 
Granting Approval of a Proposed Rule Change to Amend Rules 11.9, 
11.12, and 11.13).
---------------------------------------------------------------------------

    First, the Exchange proposes to add specificity to the Exchange's 
rule based on BZX Rule 11.9(c)(10) to make clear that although an order 
with a Discretionary Range instruction may be accompanied by a 
Displayed \12\ instruction, an order with a Discretionary Range 
instruction may also be accompanied by a Non-Displayed \13\ 
instruction, and if so, will have a non-displayed ranked price as well 
as a discretionary price. The Exchange further proposes to adopt 
language from BZX Rule 11.9(c)(10) to specifically state that resting 
orders with a Discretionary Range instruction will be executed at a 
price that uses the minimum amount of discretion necessary to execute 
the order against an incoming order. Neither of these proposed changes 
represent changes to functionality, but rather, additional specificity 
in Exchange Rules based on BZX Rule 11.9(c)(10).
---------------------------------------------------------------------------

    \12\ See Exchange Rule 11.6(e)(1).
    \13\ See Exchange Rule 11.6(e)(2).
---------------------------------------------------------------------------

    Second, the Exchange also proposes to amend its current Rule and 
functionality by adding language to 11.6(d) discussing how an order 
with a Discretionary range instruction would interact with an order 
with a Post Only instruction. Specifically, when an order with a Post 
Only instruction that is entered at the displayed or non-displayed 
ranked price of an order with a Discretionary Range instruction that 
does not remove liquidity on entry pursuant to Rule 11.6(n)(4),\14\ the 
order with a Discretionary Range instruction would be converted to an 
executable order and will remove liquidity against such incoming order. 
Similar to the proposed amendments to the Aggressive and Super 
Aggressive instructions described below, due to the fact that an order 
with a Discretionary Range instruction contains a more aggressive price 
at which it is willing to execute, the Exchange proposes to treat 
orders with a Discretionary Range instruction as aggressive orders that 
would prefer to execute at their displayed or non-displayed ranked 
price than to forgo an execution due to applicable fees or rebates. 
Accordingly, in order to facilitate transactions consistent with the 
instructions of its Users, the Exchange proposes to execute resting 
orders with a Discretionary Range instruction (and certain orders with 
an Aggressive or Super Aggressive instruction, as described below) 
against incoming orders, when such incoming orders would otherwise 
forego an execution. The Exchange notes that the determination of 
whether an order should execute on entry against resting interest, 
including against a resting order with a Discretionary Range 
instruction, is made prior to determining whether the price of such an 
incoming order should be adjusted pursuant to the Exchange's price 
sliding functionality pursuant to Rule 11.6(l). In other words, an 
execution would have

[[Page 43812]]

already occurred as set forth above before the Exchange would consider 
whether an order could be displayed and/or posted to the EDGX Book, and 
if so, at what price.
---------------------------------------------------------------------------

    \14\ Under Rule 11.6(n)(4), an order with a Post Only 
instruction or Price Adjust instruction will remove contra-side 
liquidity from the EDGX Book if the order is an order to buy or sell 
a security priced below $1.00 or if the value of such execution when 
removing liquidity equals or exceeds the value of such execution if 
the order instead posted to the EDGX Book and subsequently provided 
liquidity, including the applicable fees charged or rebates 
provided. To determine at the time of a potential execution whether 
the value of such execution when removing liquidity equals or 
exceeds the value of such execution if the order instead posted to 
the EDGX Book and subsequently provided liquidity, the Exchange will 
use the highest possible rebate paid and highest possible fee 
charged for such executions on the Exchange.
---------------------------------------------------------------------------

Examples--Order With a Discretionary Range Instruction Executes Against 
an Order With a Post Only Instruction
    Assume that the NBBO is $10.00 by $10.05, and the Exchange's BBO is 
$9.99 by $10.06. Assume that the Exchange receives a non-routable order 
to buy 100 shares at $10.00 per share designated with discretion to pay 
up to an additional $0.05 per share.
     Assume that the next order received by the Exchange is an 
order with a Post Only instruction to sell 100 shares of the security 
priced at $10.03 per share. The order with a Post Only instruction 
would not remove any liquidity upon entry pursuant to the Exchange's 
economic best interest functionality, and would post to the EDGX Book 
at $10.03. This would, in turn, trigger the discretion of the resting 
buy order with a Discretionary Range instruction and an execution would 
occur at $10.03. The order with a Post Only instruction to sell would 
be treated as the adder of liquidity and the buy order with discretion 
would be treated as the remover of liquidity.
     Assume the same facts as above, but that the incoming 
order with a Post Only instruction is priced at $10.00 instead of 
$10.03. As is true in the example above, the order with a Post Only 
instruction would not remove any liquidity upon entry pursuant to the 
Exchange's economic best interest functionality. Rather than cancelling 
the incoming order with a Post Only instruction to sell back to the 
User, particularly when the resting order with a Discretionary Range 
instruction is willing to buy the security for up to $10.05 per share, 
the Exchange proposes to execute at $10.00 the order with a Post Only 
instruction against the resting buy order with a Discretionary Range 
instruction. As is also true in the example above, the order with a 
Post Only instruction to sell would be treated as the liquidity adder 
and the buy order with discretion would be treated as the liquidity 
remover. As set forth in more detail below, if the incoming order was 
not an order with a Post Only instruction to sell, the incoming order 
could be executed at the ranked price of the order with a Discretionary 
Range instruction without restriction and would therefore be treated as 
the liquidity remover.
    Third, the Exchange proposes to modify the process by which it 
handles incoming orders that interact with Discretionary Orders. The 
Exchange proposes to specify in Rule 11.6(d) its proposed handling of a 
contra-side order that executes against a resting Discretionary Order 
at its displayed or non-displayed ranked price or that contains a time-
in-force of IOC or FOK and a price in the discretionary range by 
stating that such an incoming order will remove liquidity against the 
Discretionary Order. The Exchange also proposes to specify in Rule 
11.6(d) its handling of orders that are intended to post to the EDGX 
Book at a price within the discretionary range of an order with a 
Discretionary Range instruction. This includes, but is not limited to, 
an order with a Post Only instruction. Specifically, the Exchange 
proposes to specify in Rule 11.6(d) that any contra-side order with a 
time-in-force other than IOC or FOK and a price within the 
discretionary range but not at the displayed or non-displayed ranked 
price of an order with a Discretionary Range instruction will be posted 
to the EDGX Book and then the order with a Discretionary Range 
instruction would remove liquidity against such posted order.
    Examples--Order With a Discretionary Instruction Executes Against 
an Order Without a Post Only Instruction
    Assume that the NBBO is $10.00 by $10.05, and the Exchange's BBO is 
$9.99 by $10.06. Assume that the Exchange receives an order to buy 100 
shares of a security at $10.00 per share designated with discretion to 
pay up to an additional $0.05 per share.
     Assume that the next order received by the Exchange is an 
order with a Book Only instruction \15\ to sell 100 shares of the 
security with a TIF other than IOC or FOK priced at $10.03 per share. 
The order with a Book Only instruction would not remove any liquidity 
upon entry and would post to the EDGX Book at $10.03. This would, in 
turn, trigger the discretion of the resting buy order and an execution 
would occur at $10.03. The order with a Book Only instruction to sell 
would be treated as the adder of liquidity and the buy order with 
discretion would be treated as the remover of liquidity.
---------------------------------------------------------------------------

    \15\ The term ``Book Only'' is defined as an ``order instruction 
stating that an order will be matched against an order on the EDGX 
Book or posted to the EDGX Book, but will not route to an away 
Trading Center.'' See Exchange Rule 11.6(n)(3).
---------------------------------------------------------------------------

     Assume the same facts as above, but that the incoming 
order with a Book Only instruction is priced at $10.00 instead of 
$10.03. The order with a Book Only instruction would remove liquidity 
upon entry at $10.00 per share pursuant to the Exchange's order 
execution rule.\16\ Contrary to the examples set forth above, the order 
with a Book Only instruction to sell would be treated as the liquidity 
remover and the resting buy order with discretion would be treated as 
the liquidity adder. The Exchange notes that this example operates the 
same whether an order contains a TIF of IOC, FOK or any other TIF.
---------------------------------------------------------------------------

    \16\ See Exchange Rule 11.10.
---------------------------------------------------------------------------

    Finally, because orders with a Discretionary Range instruction have 
both a price at which they will be ranked and an additional 
discretionary price, the Exchange proposes to expressly state how the 
Exchange handles a routable order with a Discretionary Range 
instruction by stating that such an order will be routed away from the 
Exchange at its full discretionary price. As an example, assume the 
NBBO is $10.00 by $10.05 and the Exchange's BBO is $9.99 by $10.06. If 
the Exchange receives a routable order with a Discretionary Range 
instruction to buy at $10.00 with discretion to pay up to an additional 
$0.05 per share, the Exchange would route the order as a limit order to 
buy at $10.05. Any unexecuted portion of the order would be posted to 
the EDGX Book with a ranked price of $10.00 and discretion to pay up to 
$10.05.
    The Exchange notes that it has historically treated orders with a 
Discretionary Range instruction as relatively passive orders and as 
orders that, once posted to the EDGX Book, would in all cases be 
treated as the liquidity provider. The changes proposed above will 
change the handling of orders with a Discretionary Range instruction 
such that such orders are more aggressive and, thus, such orders will 
execute on the Exchange in additional circumstances than they do 
currently without regard to such orders' status as resting orders. In 
turn, orders with a Discretionary Range instruction resting on the EDGX 
Book may be treated as liquidity removers under certain circumstances, 
as outlined above.
Pegged (Rule 11.6(j))
    Current Functionality. In sum, an order with a Pegged instruction 
enables a User to specify that the order's price will peg to a price a 
certain amount away from the NBB or NBO (offset). If an order with a 
Pegged instruction displayed on the Exchange would lock the market, the 
price of the order will be automatically adjusted by the System to one 
Minimum Price Variation \17\

[[Page 43813]]

below the current NBO (for bids) or to one Minimum Price Variation 
above the current NBB (for offers). A new time stamp is created for the 
order each time it is automatically adjusted and orders with a Pegged 
instruction are not eligible for routing pursuant to Rule 11.11. For 
purposes of the Pegged instruction, the System's calculation of the 
NBBO does not take into account any orders with Pegged instructions 
that are resting on the EDGX Book. An order with a Pegged instruction 
is cancelled if an NBB or NBO, as applicable, is no longer available.
---------------------------------------------------------------------------

    \17\ The term ``Minimum Price Variation'' is defined in Exchange 
Rule 11.6(i).
---------------------------------------------------------------------------

    An order with a Pegged instruction may be a Market Peg or Primary 
Peg. An order that includes a Primary Peg instruction will have its 
price pegged by the System to the NBB, for a buy order, or the NBO for 
a sell order. In contrast, an order that includes a Market Peg 
instruction will have its price pegged by the System to the NBB, for a 
sell order, or the NBO, for a buy order.
    Proposed Functionality. The Exchange proposes to amend the Pegged 
instruction under Rule 11.6(j) by deleting subparagraph (3) to further 
align the operation of orders that include a Pegged instruction with 
the operation of Pegged Orders \18\ on BZX. As amended, Rule 11.6(j) 
would no longer provide for the re-pricing orders with a Pegged and 
Non-Displayed instruction where such orders include an offset, the 
amount of which causes them to be priced more aggressive than the 
midpoint of the NBBO. Under current subparagraph (3) of Rule 11.6(j), 
an order with a Pegged and Non-Displayed instruction that includes an 
offset that causes the order to be priced more aggressive than the 
midpoint of the NBBO is ranked at the midpoint of the NBBO pursuant to 
the re-pricing instruction under Rule 11.6(l)(3) with discretion to 
execute to the price established by the offset, or the NBB (NBO) where 
the offset for an order to sell (buy) is equal to or exceeds the NBB 
(NBO). The Exchange proposes to remove this functionality and instead 
to handle such orders in accordance with Rule 11.6(j) generally.
---------------------------------------------------------------------------

    \18\ See BZX Rule 11.9(c)(8).
---------------------------------------------------------------------------

    For example, assume the NBBO is $10.00 by $10.05. A Limit Order is 
entered into the System to buy 500 shares with a Non-Displayed and 
Market Peg instruction and offset of -$0.02. Because the order's offset 
causes it to be priced more aggressively than the midpoint of the NBBO, 
under current functionality it would be ranked at $10.025, the midpoint 
of the NBBO, with discretion to execute to $10.03, the price 
established by the offset.\19\ As proposed, the order with a Non-
Displayed and Market Peg instruction and offset of -$0.02 will ranked 
at $10.03, the price established by the offset and not the midpoint of 
the NBBO, as is currently the case.
---------------------------------------------------------------------------

    \19\ In such cases, the order will be given a new time stamp 
each time it is re-priced by the System in response to changes in 
the midpoint of the NBBO.
---------------------------------------------------------------------------

Re-Pricing (Rule 11.6(l))
    The Exchange currently offers re-pricing instructions which, in all 
cases, result in the ranking and/or display of an order at a price 
other than its limit price in order to comply with applicable 
securities laws and Exchange Rules. Specifically, the Exchange 
currently offers re-pricing instructions to ensure compliance with 
Regulation NMS and Regulation SHO. The re-pricing instructions 
currently offered by the Exchange re-price and display an order upon 
entry and in certain cases again re-price and re-display an order at a 
more aggressive price based on changes in the NBBO. Rule 11.6(l) sets 
forth the re-pricing instructions currently available to Users with 
regard to Regulation NMS compliance--Price Adjust, and Hide Not Slide, 
as well as a separate re-pricing process with regard to Regulation SHO 
compliance. As described below, the Exchange now proposes to amend its 
re-pricing instructions to align and streamline Exchange functionality 
with that of BZX.
Re-Pricing Instructions To Comply With Rule 610(d) of Regulation NMS
    The Exchange proposes to amend its re-pricing instructions to 
comply with Rule 610(d) of Regulation NMS as follows: (i) Amend the 
Price Adjust instruction under Rule 11.6(l)(1)(A) to: (A) divide the 
rule into subparagraphs (i), (ii), and (iii); (B) clarify the order 
must be a Locking Quotation \20\ or Crossing Quotation \21\ of an 
external market; and (C) propose new subparagraph (iv) described below; 
and (ii) replace the Hide Not Slide instruction under Rule 
11.6(l)(1)(B) with Display-Price Sliding, which would operate in a 
similar fashion to the display-price sliding process currently 
available on BZX as described under BZX Rule 11.9(g)(1).
---------------------------------------------------------------------------

    \20\ The term ``Locking Quotation'' is defined as ``[t]he 
display of a bid for an NMS stock at a price that equals the price 
of an offer for such NMS stock previously disseminated pursuant to 
an effective national market system plan, or the display of an offer 
for an NMS stock at a price that equals the price of a bid for such 
NMS stock previously disseminated pursuant to an effective national 
market system plan in violation of Rule 610(d) of Regulation NMS.'' 
See Exchange Rule 11.6(g).
    \21\ The term ``Crossing Quotation'' is defined as ``[t]he 
display of a bid (offer) for an NMS stock at a price that is higher 
(lower) than the price of an offer (bid) for such NMS stock 
previously disseminated pursuant to an effective national market 
system plan in violation of Rule 610(d) of Regulation NMS.'' See 
Exchange Rule 11.6(c).
---------------------------------------------------------------------------

    Price Adjust Re-Pricing (Rule 11.6(l)(1)(A)). Under the Price 
Adjust instruction, where a buy (sell) order would be a Locking 
Quotation or Crossing Quotation if displayed by the System on the EDGX 
Book at the time of entry, the order will be displayed and ranked \22\ 
at a price that is one Minimum Price Variation lower (higher) than the 
Locking Price.\23\ The Exchange proposes to modify the operation of the 
Price Adjust instruction such that an order must be a Locking Quotation 
or Crossing Quotation of an external market, not the EDGX Book, in 
order be eligible for the re-pricing. This change will provide 
additional specificity within the Exchange's rules regarding the 
applicability of the Price Adjust instruction as well as align the 
description with BZX's Price Adjust process described under BZX Rule 
11.9(g)(2).\24\ This change is also consistent with display-price 
sliding on BZX and Display-Price Sliding discussed below, under which 
orders are only re-priced where they are a Locking Quotation or 
Crossing Quotation of an external market, and not the BZX order book or 
EDGX Book, as applicable. Other than as described above, these 
provisions will remain unchanged and be set forth under subparagraph 
(i), so that the Exchange may renumber the following provisions of Rule 
11.6(l)(1)(A) as set forth below.
---------------------------------------------------------------------------

    \22\ For purposes of the description of the re-pricing 
instructions under proposed Rule 11.6(l), the terms ``ranked'' and 
``priced'' are synonymous and used interchangeably.
    \23\ The term ``Locking Price'' is defined as ``[t]he price at 
which an order to buy (sell), that if displayed by the System on the 
EDGX Book, either upon entry into the System, or upon return to the 
System after being routed away, would be a Locking Quotation.'' See 
Exchange Rule 11.6(f).
    \24\ The description of the Price Adjust process under BATS Rule 
11.9(g)(2), states that ``[a]n order eligible for display by the 
Exchange that, at the time of entry, would create a violation of 
Rule 610(d) of Regulation NMS by locking or crossing a Protected 
Quotation of an external market will be ranked and displayed by the 
System at one minimum price variation below the current NBO (for 
bids) or to one minimum price variation above the current NBB (for 
offers) . . .'' (emphasis added). Thus, an order will only be re-
priced pursuant to its Price Adjust process where it locks or 
crosses a Protected Quotation of an external market, and not BATS. 
The Exchange notes that this reflects a recent change to BATS Rule 
11.9(g)(2). See Securities Exchange Act Release No. 75324 (June 29, 
2015) (SR-BATS-2015-47) (Notice of Filing and Immediate 
Effectiveness of a Proposed Rule Change to Amend Rule 11.9 of BATS 
Exchange, Inc., to Modify its Price Adjust Functionality).
---------------------------------------------------------------------------

    The Exchange proposes to restructure the provisions of the current 
Rule by

[[Page 43814]]

separating rule text and adopting additional subparagraph references, 
subparagraph (ii) and (iii).
    The Exchange also proposes to add new subparagraph (iv) to Rule 
11.6(l)(1)(A) which would cover where an order with a Price Adjust 
instruction and a Post Only instruction would be a Locking Quotation or 
Crossing Quotation of the Exchange. The proposed amendments to Rule 
11.6(l)(1)(A) are based on BZX Rule 11.9(g)(2)(D). To the extent the 
amended text of Exchange Rule 11.6(l)(1)(A) differs from BZX Rule 
11.9(g)(2)(D), such differences are necessary to conform the rule with 
existing rule text.
    As noted above, an order subject to the Price Adjust instruction 
will only be re-priced where it would be a Locking Quotation of 
Crossing Quotation of an external market, and not the Exchange. In such 
case, any display-eligible order with a Price Adjust instruction and a 
Post Only instruction that would be a Locking Quotation or Crossing 
Quotation of the Exchange upon entry will be executed as set forth in 
Rule 11.6(n)(4) \25\ or cancelled. For example, assume the NBBO is 
$10.00 by $10.01 and an order to sell at $10.01 is resting on the EDGX 
Book. Further assume that no other Trading Center \26\ is displaying an 
order to sell at $10.01. Assume that the Exchange receives an order to 
buy with a Post Only instruction and Price Adjust instruction at 
$10.01. The incoming order to buy will be cancelled unless, pursuant to 
Rule 11.6(n)(4), the value of such execution when removing liquidity 
equals or exceeds the value of such execution if the order instead 
posted to the EDGX Book and subsequently provided liquidity. The 
incoming order to buy will not be posted to the EDGX Book and re-priced 
pursuant to the Price Adjust instruction.
---------------------------------------------------------------------------

    \25\ See supra note 14.
    \26\ The term ``Trading Center'' is defined as ``[o]ther 
securities exchanges, facilities of securities exchanges, automated 
trading systems, electronic communications networks or other broker 
dealers.'' See Exchange Rule 11.6(r).
---------------------------------------------------------------------------

Replacing Hide Not Slide With Display-Price Sliding (Rule 
11.6(l)(1)(B))
    The Exchange proposes to replace the Hide Not Slide re-pricing 
instruction under Rule 11.6(l)(1)(B) with Display-Price Sliding, which 
would operate the same fashion as the Display-Price Sliding process 
currently available on BZX and described under BZX Rule 11.9(g)(1).\27\ 
The main differences between the current operation of orders with a 
Hide Not Slide instruction and the proposed Display-Price Sliding 
instruction are: (i) Orders with a Hide Not Slide instruction are 
ranked at the midpoint of the NBBO with discretion to the Locking Price 
while orders with Display-Price Sliding instruction are ranked at the 
Locking Price; and (ii) orders with the Hide Not Slide and Post Only 
instructions are re-priced if they would be a Locking Quotation of the 
EDGX Book, while orders with the Display-Price Sliding and Post Only 
instructions would be executed in accordance with Rule 11.6(n)(4) \28\ 
or cancelled if they would be a Locking Quotation of the EDGX Book, but 
re-priced if they would be a Locking Quotation of an external market.
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    Under the current Hide Not Slide instruction, an order that would 
be a Locking Quotation or Crossing Quotation if displayed by the System 
on the EDGX Book at the time of entry, will be displayed at a price 
that is one Minimum Price Variation lower (higher) than the Locking 
Price for orders to buy (sell), and ranked at the mid-point of the NBBO 
with discretion to execute at the Locking Price. However, if a contra-
side order that equals the Locking Price is displayed by the System on 
the EDGX Book, the order subject to the Hide Not Slide instruction will 
be ranked at the mid-point of the NBBO but its discretion to execute at 
the Locking Price will be suspended unless and until there is no 
contra-side displayed order on the EDGX Book that equals the Locking 
Price. Where the NBBO changes such that the order, if displayed by the 
System on the EDGX Book at the Locking Price, would not be a Locking 
Quotation or Crossing Quotation, the System will rank and display such 
orders at the Locking Price. The order will not be subject to further 
re-ranking and will be displayed on the EDGX Book at the Locking Price 
until executed or cancelled by the User. The order will receive a new 
time stamp when it is ranked at the Locking Price. Pursuant to Rule 
11.9, all orders that are re-ranked and re-displayed by the System on 
the EDGX Book pursuant to the Hide Not Slide instruction retain their 
priority as compared to each other based upon the time such orders were 
initially received by the System.
    The Exchange proposes to replace the Hide Not Slide instruction 
under Rule 11.6(l)(1)(B) with the Display-Price Sliding instruction, 
which would operate in an identical fashion as the Display-Price 
Sliding process currently available on BZX.\29\ Display-Price Sliding 
would be an order instruction requiring that where an order would be a 
Locking Quotation or Crossing Quotation of an external market if 
displayed by the System on the EDGX Book at the time of entry, such 
order will be ranked at the Locking Price and displayed by the System 
at one Minimum Price Variation lower (higher) than the Locking Price 
for orders to buy (sell). A User may elect for the Display-Price 
Sliding instruction to only apply where their display-eligible order 
would be a Locking Quotation of an external market upon entry (``Lock 
Only''). In such cases, the User's display-eligible order would be 
cancelled if the order would be a Crossing Quotation of an external 
market upon entry.
---------------------------------------------------------------------------

    \29\ See BATS Rule 11.9(g)(1). See also the BATS Display-Price 
Sliding Releases, supra note 27.
---------------------------------------------------------------------------

    For example, assume the Exchange has a posted and displayed bid to 
buy at $10.10 and a posted and displayed offer to sell $10.13. Assume 
the NBBO is $10.10 by $10.12. If the Exchange receives an order with a 
Book Only instruction to buy at $10.12, the Exchange will rank the 
order to buy at $10.12 and display the order at $10.11 because 
displaying the bid at $10.12 would cause it to be a Locking Quotation 
of an external market's Protected Offer to sell for $10.12. If the NBO 
then moved to $10.13, the Exchange would un-slide the bid to buy and 
display it at its ranked price (and limit price) of $10.12.
    As an example of the Lock-Only option for Display-Price Sliding, 
assume the Exchange has a posted and displayed bid to buy at $10.10 and 
a posted and displayed offer to sell at $10.14. Assume the NBBO is 
$10.10 by $10.12. If the Exchange receives an order with a Book Only 
instruction to buy 100 shares at $10.13 and the User has elected the 
Lock-Only option for Display-Price Sliding, the Exchange will cancel 
the order back to the User. To reiterate a basic example of Display-
Price Sliding, if instead the User applied Display-Price Sliding (and 
not the Lock-Only option for Display-Price Sliding), the Exchange would 
rank the order to buy at $10.12 and display the order at $10.11 because 
displaying the bid at $10.13 would cause it to be a Crossing Quotation 
of an external market's Protected Offer to sell for $10.12. If the NBO 
then moved to $10.13, the Exchange would un-slide the bid to buy and 
display it at $10.12.
    As proposed, an order subject to the Display-Price Sliding 
instruction will retain its original limit price irrespective

[[Page 43815]]

of the prices at which such order is ranked and displayed. An order 
subject to the Display-Price Sliding instruction will be displayed at 
the most aggressive price possible and receive a new time stamp should 
the NBBO change such that the order would no longer be a Locking 
Quotation or Crossing Quotation of an external market. As is true under 
the Price Adjust and current Hide Not Slide instructions, all orders 
that are re-ranked and re-displayed pursuant to the Display-Price 
Sliding instruction will retain their priority as compared to other 
orders subject to the Display-Price Sliding instruction based upon the 
time such orders were initially received by the Exchange. Following the 
initial ranking and display of an order subject to the Display-Price 
Sliding instruction, an order will only be re-ranked and re-displayed 
to the extent it achieves a more aggressive price, provided, however, 
that the Exchange will re-rank an order at its displayed price in the 
event such order's displayed price would be a Locking Quotation or 
Crossing Quotation. Such event will not result in a change in priority 
for the order at its displayed price. This will avoid the potential of 
a ranked price that crosses the Protected Quotation displayed by such 
external market, which could, in turn, lead to a trade through of such 
Protected Quotation at such ranked price. The Exchange notes that, as 
described below, when an external market crosses the Exchange's 
Protected Quotation and the Exchange's Protected Quotation is a 
displayed order subject to Display-Price Sliding, the Exchange proposes 
to re-rank such order at the displayed price. Thus, the order displayed 
by the Exchange will still be ranked and permitted to execute at a 
price that is consistent with Rule 611(b)(4) of Regulation NMS.\30\
---------------------------------------------------------------------------

    \30\ 17 CFR 242.611(b)(4). See also the BATS Display-Price 
Sliding Releases, supra note 27.
---------------------------------------------------------------------------

    The ranked and displayed prices of an order subject to the Display-
Price Sliding instruction may be adjusted once or multiple times 
depending upon the instructions of a User and changes to the prevailing 
NBBO. Multiple re-pricing is optional and must be explicitly selected 
by a User before it will be applied. The Exchange's default Display-
Price Sliding instruction will only adjust the ranked and displayed 
prices of an order upon entry and then the displayed price one time 
following a change to the prevailing NBBO, provided however, that if 
such an order's displayed price becomes a Locking Quotation or Crossing 
Quotation then the Exchange will adjust the ranked price of such order 
and it will not be further re-ranked or re-displayed at any other 
price. Orders subject to the optional multiple price sliding process 
will be further re-ranked and re-displayed as permissible based on 
changes to the prevailing NBBO.
    As an example of the multiple re-pricing option for Display-Price 
Sliding, assume the Exchange has a posted and displayed bid to buy at 
$10.10 and a posted and displayed offer to sell at $10.14. Assume the 
NBBO is $10.10 by $10.12. If the Exchange receives an order with a Book 
Only instruction to buy at $10.13, the Exchange would rank the order to 
buy at $10.12 and display the order at $10.11 because displaying the 
bid at $10.13 would cause it to be a Crossing Quotation of an external 
market's Protected Offer to sell for $10.12. If the NBO then moved to 
$10.13, the Exchange would un-slide the bid to buy, rank it at $10.13 
and display it at $10.12. Where the User did not elect the multiple re-
pricing option for Display-Price Sliding, the Exchange would not 
further adjust the ranked or displayed price following this un-slide. 
However, under the multiple re-pricing option, if the NBO then moved to 
$10.14, the Exchange would un-slide the bid to buy and display it at 
its full limit price of $10.13.
    Pursuant to proposed Rule 11.6(l)(1)(B)(iv), any display-eligible 
order with a Post Only instruction that would be a Locking Quotation or 
Crossing Quotation of the Exchange upon entry will be executed as set 
forth in Rule 11.6(n)(4) or cancelled. Consistent with the principle of 
not re-pricing orders to avoid executions, in the event the NBBO 
changes such that an order with a Post Only instruction subject to 
Display-Price Sliding instruction would be ranked at a price at which 
it could remove displayed liquidity from the EDGX Book, the order will 
be executed as set forth in Rule 11.6(n)(4) or cancelled.\31\
---------------------------------------------------------------------------

    \31\ As noted above, the Exchange will execute an order with a 
Post Only instruction in certain circumstances where the value of 
such execution when removing liquidity equals or exceeds the value 
of such execution if the order instead posted to the EDGX Book and 
subsequently provided liquidity, including the applicable fees 
charged or rebates provided. See supra note 14.
---------------------------------------------------------------------------

    Pursuant to proposed Rule 11.6(l)(1)(B)(v), an order with a Post 
Only instruction will be permitted to post and be displayed opposite 
the ranked price of orders subject to Display-Price Sliding 
instruction. In the event an order subject to the Display-Price Sliding 
instruction is ranked on the EDGX Book with a price equal to an 
opposite side order displayed by the Exchange, it will be subject to 
processing as set forth in Rule 11.10(a)(4), which is described in 
greater detail below.
    For example, assume the Exchange has a posted and displayed bid to 
buy at $10.10 and a posted and displayed offer to sell at $10.12. 
Assume the NBBO (including Protected Quotations of other external 
markets) is also $10.10 by $10.12. If the Exchange receives an order 
with a Post Only instruction to buy at $10.12 per share, unless 
executed pursuant to Rule 11.6(n)(4),\32\ the Exchange would cancel the 
order back to the User because absent the order with a Post Only 
instruction, the order to buy at $10.12 would be able to remove the 
order to sell $10.12, and, as explained above, the Exchange would no 
longer offer re-pricing to avoid executions against orders displayed by 
the Exchange.
---------------------------------------------------------------------------

    \32\ Id.
---------------------------------------------------------------------------

    If the Exchange did not have a displayed offer to sell at $10.12 in 
the example above, but instead the best offer on the EDGX Book was 
$10.13, the Exchange would apply Display-Price Sliding to the incoming 
order to buy by ranking such order at $10.12 and displaying the order 
at $10.11. The EDGX Book would now be displayed as $10.11 by $10.13. 
Assume, however, that after price sliding the incoming order to buy 
from $10.12 to a display price of $10.11, the Exchange received an 
order with a Post Only instruction to sell at $10.12, thus joining the 
NBO. The order with a Post Only instruction would be permitted to post 
and be displayed opposite the ranked price of orders subject to 
display-price sliding. Accordingly, the Exchange would allow such 
incoming order with a Post Only instruction to sell at $10.12 to post 
and display on the EDGX Book, as described above, with an opposite side 
order subject to Display-Price Sliding displayed at $10.11. Assume that 
the next Protected Offer displayed by all external markets other than 
the Exchange moved to $10.13. In this situation the Exchange would un-
slide but then cancel the bid at $10.12 because, as proposed, in the 
event the NBBO changes such that an order with a Post Only instruction 
subject to Display-Price Sliding would un-slide and would be ranked at 
a price at which it could remove displayed liquidity from the EDGX Book 
(i.e., when the Exchange is at the NBB or NBO) the Exchange proposes to 
execute \33\ or cancel such order.

Re-Pricing Instructions To Comply With Rule 201 of Regulation SHO
    Current Functionality. Under Rule 11.6(l)(2), an order to sell with 
a Short Sale instruction that, at the time of entry, could not be 
executed or displayed in compliance with Rule 201 of Regulation SHO 
will be re-priced by the System at the Permitted Price.\34\ The default 
short sale re-pricing process will only re-price an order upon entry 
and one additional time to reflect a decline in the NBB. Depending upon 
the instructions of a User, to reflect declines in the NBB the System 
will continue to re-price and re-display a short sale order at the 
Permitted Price down to the order's limit price. In the event the NBB 
changes such that the price of an order with a Non-Displayed 
instruction subject to Rule 201 of Regulation SHO would be a Locking 
Quotation or Crossing Quotation, the order will receive a new time 
stamp, and will be re-priced by the System to the mid-point of the 
NBBO.
---------------------------------------------------------------------------

    \34\ The term ``Permitted Price'' is defined as ``[t]he price at 
which a sell order will be displayed at one Minimum Price Variation 
above the NBB.'' See Exchange Rule 11.6(k).
---------------------------------------------------------------------------

    Current Rule 11.6(l)(2) states that: (i) When a Short Sale Circuit 
Breaker is in effect, the System will execute a sell order with a 
Displayed and Short Sale instruction at the price of the NBB if, at the 
time of initial display of the sell order with a Short Sale 
instruction, the order was at a price above the then current NBB; (ii) 
orders with a Short Exempt instruction will not be subject to re-
pricing under amended Rule 11.6(l)(2); and (iii) the re-pricing 
instructions to comply with Rule 610(d) of Regulation NMS will continue 
to be ignored for an order to sell with a Short Sale instruction when a 
Short Sale Circuit Breaker is in effect and the re-pricing instructions 
to comply with Rule 201 of Regulation SHO under this Rule will apply.
    Proposed Functionality. The Exchange proposes to make the below 
changes to align the operation of the Exchange's short sale re-pricing 
process with that of BZX under BZX Rule 11.9(g)(5). First, the Exchange 
proposed to amend Rule 11.6(l)(2)(A) to only re-price an order upon 
entry, and not one additional time to reflect a decline in the NBB. 
This is consistent with the BZX short sale price sliding process under 
BZX Rule 11.9(g)(5)(A), which only re-prices an order upon entry. 
Second, the Exchange's rules currently state that in the event the NBB 
changes such that the price of an order with a Non-Displayed 
instruction subject to Rule 201 of Regulation SHO would be a Locking 
Quotation or Crossing Quotation, the order will receive a new time 
stamp, and will be re-priced by the System to the mid-point of the 
NBBO. As proposed, such order will be re-priced to the Permitted Price, 
and not the mid-point of the NBBO. This is consistent with BZX Rule 
11.9(g)(5)(A), which also re-prices order subject to Rule 201 of 
Regulation SHO to the Permitted Price in such cases.
    The Exchange also proposes to delete language from Rule 
11.6(l)(2)(A) regarding orders with a Short Sale instruction and Price 
Adjust instruction being re-priced to the Permitted Price. The Exchange 
also proposes to delete language from Rule 11.6(l)(2)(A) regarding 
orders with a Short Sale instruction and a Hide Not Slide instruction 
being re-priced to the mid-point of the NBBO. This language is proposed 
to be deleted because, as discussed above, the Hide Not Slide 
instruction is being replaced by Display-Price Sliding, and because all 
orders with a Display-Price Sliding or Price Adjust instruction will be 
subject to the short sale re-pricing process under the Rule.
    Lastly, the Exchange proposes to amend Rule 11.6(l)(2)(D) to align 
with BZX Rule 11.9(g)(6) and state that where an order is subject to 
either a Display-Price Sliding instruction or a Price Adjust 
instruction and also contains a Short Sale instruction when a Short 
Sale Circuit Breaker is in effect, the re-pricing instructions to 
comply with Rule 201 of Regulation SHO will apply. The Exchange does 
not propose this change to alter the meaning of Rule 11.6(l)(2)(D), but 
rather, to align the language with BZX Rule 11.9(g) in order to provide 
consistent rules across the Exchange and BZX.
Re-Pricing of Orders With a Non-Displayed Instruction and Odd Lot 
Orders (Rule 11.6(l)(3))
    Current Functionality. Under Rule 11.6(l)(3), both an order with a 
Non-Displayed instruction or an order with an Odd Lot size that is 
priced better than the midpoint of the NBBO will be ranked at the 
midpoint of the NBBO with discretion to execute to its limit price. For 
securities priced equal to or greater than $1.00 where the midpoint of 
the NBBO is in an increment smaller than $0.01, an order buy (sell) 
with an Odd Lot size and a Displayed instruction priced better than the 
midpoint of the NBBO will be displayed at the next full penny increment 
below (above) the midpoint of the NBBO. The price of the order is 
automatically re-ranked by the System in response to changes in the 
NBBO until it reaches its limit price. A new time stamp is created for 
the order each time the midpoint of the NBBO changes. All orders with a 
Non-Displayed instruction and orders with an Odd Lot size that are re-
ranked to the midpoint of the NBBO will retain their priority as 
compared to other orders with a Non-Displayed instruction and orders 
with an Odd Lot size, respectively, based upon the time such orders 
were ranked at the midpoint of the NBBO. While a User may affirmatively 
elect that a buy (sell) order with a Non-Displayed instruction Cancel 
Back \35\ when the order's limit price is greater (less) than the NBO 
(NBB), they are unable to do so for an order with an Odd Lot size. In 
such case, the User may cancel the order.
---------------------------------------------------------------------------

    \35\ The term ``Cancel Back'' is defined as ``[a]n instruction 
the User may attach to an order instructing the System to 
immediately cancel the order when, if displayed by the System on the 
EDGX Book at the time of entry, or upon return to the System after 
being routed away, would create a violation of Rule 610(d) of 
Regulation NMS or Rule 201 of Regulation SHO, or the order cannot 
otherwise be executed or posted by the System to the EDGX Book at 
its limit price.'' See Exchange Rule 11.6(b).
---------------------------------------------------------------------------

    Proposed Functionality. The Exchange proposes to amend Rule 
11.6(l)(3) to align with BZX Rule 11.9(g)(4). To the extent the amended 
text of Exchange Rule 11.6(l)(3) differs from BZX Rule 11.9(g)(4), such 
differences are necessary to conform the rule to existing rule text. As 
amended, orders with a Non-Displayed instruction or orders of Odd Lot 
size priced better than the NBBO will no longer be ranked at the mid-
point of the NBBO. Amended Rule 11.6(l)(2) would state that in order to 
avoid potentially trading through Protected Quotations of external 
markets, any order with a Non-Displayed instruction that is subject to 
the Display-Price Sliding or Price Adjust instruction would be ranked 
at the Locking Price on entry. In the event the NBBO changes such that 
an order with a Non-Displayed instruction subject to the Display-Price 
Sliding or Price Adjust instruction would cross a Protected Quotation 
of an external market, the order will receive a new time stamp, and 
will be ranked by the System at the Locking Price. In the event an 
order with a Non-Displayed instruction has been re-priced by the 
System, such order with a Non-Displayed instruction is not re-priced by 
the System unless it again would cross a Protected Quotation of an 
external market. The Rule would no longer make particular reference to 
orders of Odd Lot size, as those orders would be treated like orders of 
Round Lot or Mixed Lot size as currently done on BZX. This 
functionality is equivalent to the handling of displayable orders

[[Page 43817]]

pursuant to the Display-Price Sliding instruction except that such 
orders will not have a displayed price.
Aggressive (Rule 11.6(n)(1))
    Aggressive is an order instruction that directs the System to route 
the order if an away Trading Center crosses the limit price of the 
order resting on the EDGX Book. Based on BZX Rule 11.13(a)(4)(A), the 
Exchange proposes to also amend Rule 11.6(n)(1) to state that any 
routable order with a Non-Displayed instruction that is resting on the 
EDGX Book and is crossed by an away Trading Center will be 
automatically routed to the Trading Center displaying the Crossing 
Quotation. To the extent the amended text of Exchange Rule 11.6(n)(1) 
differs from BZX Rule 11.13(a)(4)(A), such differences are necessary to 
conform the rule with existing rule text.
Super Aggressive (Rule 11.6(n)(2))
    Super Aggressive is an order instruction that directs the System to 
route an order when an away Trading Center locks or crosses the limit 
price of the order resting on the EDGX Book. A User may designate an 
order as Super Aggressive solely to routable orders posted to the EDGX 
Book with remaining size of an Odd Lot. Based on BZX Rule 
11.13(b)(4)(C),\36\ the Exchange proposes to amend Rule 11.6(n)(2) to 
state that when any order with a Super Aggressive instruction is locked 
by an incoming order with a Post Only instruction that does not remove 
liquidity pursuant to Rule 11.6(n)(4),\37\ the order with a Super 
Aggressive instruction would be converted to an executable order and 
will remove liquidity against such incoming order. Rule 11.6(n)(2) 
would further state that notwithstanding the foregoing, if an order 
that does not contain a Super Aggressive instruction maintains higher 
priority than one or more Super Aggressive eligible orders, the Super 
Aggressive eligible order(s) with lower priority will not be converted, 
as described above, and the incoming order with a Post Only instruction 
will be posted or cancelled in accordance with Rule 11.6(n)(4). To the 
extent the amended text of Exchange Rule 11.6(n)(2) differs from BZX 
Rule 11.13(b)(4)(C), such differences are necessary to conform the rule 
with existing rule text.
---------------------------------------------------------------------------

    \36\ See supra note 11.
    \37\ As noted above, the Exchange will execute an order with a 
Post Only instruction in certain circumstances where the value of 
such execution when removing liquidity equals or exceeds the value 
of such execution if the order instead posted to the EDGX Book and 
subsequently provided liquidity, including the applicable fees 
charged or rebates provided. See supra note 14.
---------------------------------------------------------------------------

    The Exchange proposes to apply this logic in order to facilitate 
executions that would otherwise not occur due to the Post Only 
instruction requirement to not remove liquidity. Because a Super 
Aggressive Re-Route eligible order is willing to route to an away 
Trading Center and remove liquidity (i.e., pay a fee at such Trading 
Center) when it becomes either a Locking Quotation or Crossing 
Quotation, the Exchange believes it is reasonable and consistent with 
the instruction to force an execution between an incoming order with a 
Post Only instruction and an order that has been posted to the EDGX 
Book with the Super Aggressive instruction. The Exchange notes that the 
determination of whether an order should execute on entry against 
resting interest, including against resting orders with a Super 
Aggressive instruction, is made prior to determining whether the price 
of such an incoming order should be adjusted pursuant to the Exchange's 
re-pricing instructions under Rule 11.6(l). Like BZX Rule 
11.13(b)(4)(C), the Exchange has limited the proposed language to 
orders with a Post Only instruction that would lock the price of an 
order with a Super Aggressive instruction because orders with a Post 
Only instruction that cross resting orders will always remove liquidity 
because it is in their economic best interest to do so.\38\ Also like 
BZX Rule 11.13(b)(4)(C), the Exchange proposes to make clear that 
although it will execute an order with a Super Aggressive instruction 
against an order with a Post Only instruction that would create a 
Locking Quotation, if an order that does not contain a Super Aggressive 
instruction maintains higher priority than one or more Super Aggressive 
eligible orders, the Super Aggressive eligible order(s) with lower 
priority will not be converted, as described above, and the incoming 
order with a Post Only instruction will be posted or cancelled in 
accordance with Rule 11.6(n)(4). The Exchange believes it is necessary 
to avoid applying the Super Aggressive functionality to routable orders 
that are resting behind orders that are not eligible for routing to 
avoid violating the Exchange's priority rule, Rule 11.9.

Example--Super Aggressive Re-Route and Orders With a Post Only 
Instruction
    Assume that the Exchange receives an order to buy 300 shares of a 
security at $10.10 per share designated with a Super Aggressive 
instruction. Assume further that the NBBO is $10.09 by $10.10 when the 
order is received, and the Exchange's lowest offer is priced at $10.11. 
The Exchange will route the order away from the Exchange as a bid to 
buy 300 shares at $10.10. Assume that the order obtains one 100 share 
execution through the routing process and then returns to the Exchange. 
The Exchange will post the order as a bid to buy 200 shares at $10.10. 
If the Exchange subsequently receives an order with a Post Only 
instruction to sell priced at $10.09 per share, such order will execute 
against the posted order to buy with an execution price of $10.10. The 
posted buy order will be treated as the liquidity provider and the 
incoming order with a Post Only instruction to sell will be treated as 
the liquidity remover, based on Exchange Rule 11.6(n)(4) that executes 
orders with a Post Only instruction upon entry if such execution is in 
their economic interest.
    However, assuming the same facts as above, if the incoming order 
with a Post Only instruction to sell is priced at $10.10 and thus does 
not remove liquidity pursuant to the economic best interest 
functionality, the posted order with a Super Aggressive instruction 
will execute against such order at $10.10. In this scenario, the posted 
order to buy will be treated as the liquidity remover and the incoming 
order with a Post Only instruction to sell will be treated as the 
liquidity provider.
    Finally, assume that the NBBO is $10.10 by $10.11 and that the 
Exchange has a displayed bid to buy 100 shares of a security at $10.10 
and a displayed offer to sell 100 shares of a security at $10.11. 
Assume that the displayed bid has not been designated with the Super 
Aggressive instruction. Assume next that the Exchange receives a second 
displayable bid to buy 100 shares of the same security at $10.10 that 
has been designated as routable and subject to the Super Aggressive 
instruction. Because there is no liquidity to which the Exchange can 
route the order, the second order will post to the EDGX Book as a bid 
to buy at $10.10 behind the original displayed bid to buy at $10.10. If 
the Exchange then received an order with a Post Only instruction to 
sell 100 shares at $10.10 then no execution would occur because the 
incoming order with a Post Only instruction cannot remove liquidity at 
$10.10 based on the economic best interest analysis, the first order 
with priority to buy at $10.10 was not designated with the Super 
Aggressive instruction and the second booked order to buy at $10.10 is 
not permitted to bypass the first order as this would

[[Page 43818]]

result in a violation of the Exchange's priority rule, Rule 11.9.
Post Only (Rule 11.6(n)(4))
    As discussed above, the Exchange proposes to replace the Hide Not 
Slide re-pricing instruction with Display-Price Sliding. Therefore, the 
Exchange also proposes to amend the definition of Post Only under Rule 
11.6(n)(4) to replace a reference to the Hide Not Slide instruction 
with Display-Price Sliding. In sum, Post Only is an instruction that 
may be attached to an order that is to be ranked and executed on the 
Exchange pursuant to Rule 11.9 and Rule 11.10(a)(4) or cancelled, as 
appropriate, without routing away to another trading center except that 
the order will not remove liquidity from the EDGX Book, except as 
described below. As amended, an order with a Post Only instruction and 
a Display-Price Sliding, rather than Hide Not Slide, or Price Adjust 
instruction will remove contra-side liquidity from the EDGX Book if the 
order is an order to buy or sell a security priced below $1.00 or if 
the value of such execution when removing liquidity equals or exceeds 
the value of such execution if the order instead posted to the EDGX 
Book and subsequently provided liquidity, including the applicable fees 
charged or rebates provided.
Time-In-Force (``TIF'') (Rule 11.6(q))
    The Exchange proposes to amend its TIF instructions to align with 
BZX Rule 11.9(b). To the extent the amended text of Exchange Rule 
11.6(q) differs from BZX Rule 11.9(b), such differences are necessary 
to conform the rule with existing Exchange rule text.
    First, the Exchange proposes to align the definition of Immediate-
or-Cancel (``IOC'') under Rule 11.6(q)(1) with BZX Rule 11.9(b)(1) to 
make clear that an order with an IOC instruction that does not include 
a Book Only instruction and that cannot be executed in accordance with 
Rule 11.10(a)(4) on the System when reaching the Exchange will be 
eligible for routing away pursuant to Rule 11.11.\39\ Under current 
rules, the TIF of IOC indicates that an order is to be executed in 
whole or in part as soon as such order is received and the portion not 
executed is to be cancelled. Based on BZX Rule 11.9(b)(1), the Exchange 
proposes to expand upon the description of IOC to specify that an order 
with such TIF may be routed away from the Exchange but that in no event 
will an order with such TIF be posted to the EDGX Book. Also like BZX, 
the Exchange notes that an order with an IOC instruction routed away 
from the Exchange are in turn routed with an IOC instruction.
---------------------------------------------------------------------------

    \39\ See supra note 11.
---------------------------------------------------------------------------

    Second, the Exchange proposes to amend the definition of the Fill-
or-Kill (``FOK'') under Rule 11.6(q)(3) to align with BZX Rule 
11.9(b)(6) to make clear that an order with a TIF instruction of FOK is 
not eligible for routing away pursuant to Rule 11.11.\40\ Although 
orders with a TIF of FOK are generally treated the same as order with a 
TIF of IOC, the Exchange does not permit routing of orders with an 
order with a TIF of FOK because the Exchange is unable to ensure the 
instruction of FOK (i.e., execution of an order in its entirety) 
through the routing process.

Rule 11.8, Order Types
    The Exchange proposes to amend the description of Limit Orders 
under Rule 11.8(b) to align its operation with existing BZX Rules and 
functionality as well as to reflect the relevant proposed changes 
discussed above. In addition, the Exchange proposes to amend Rule 
11.8(d) to replace the MidPoint Match (``MPM'') order type with Market 
Peg order type, which would operate in the same fashion as identical 
order types available on EDGA and BZX. Each of these changes are 
described in more detail below.
    Limit Orders (Rule 11.8(b)). The Exchange proposes to amend Rules 
11.8(b) to: (i) update the description of the inclusion of a 
Discretionary Range instruction on a Limit Order; (ii) replace 
references to Hide Not Slide with Display-Price Sliding under 
subparagraph (10); and (iii) amend subparagraph (12) to update the 
description of the re-pricing of orders with a Non-Displayed 
instruction, both of which are intended to reflect proposed changes to 
this functionality discussed above.
    First, the Exchange proposes to re-locate within Rule 11.8(b) and 
re-word the statement regarding the inclusion of a Discretionary Range 
on a Limit Order. Current Rule 11.8(b)(8) currently states that a 
``User may include a Discretionary Range instruction.'' This ability to 
include a Discretionary Range instruction on a Limit Order is currently 
grouped with other functionality that can be elected for Limit Orders 
that also include a Post Only or Book Only instruction as well as 
specified time-in-force instructions for orders that can be entered 
into the System and post to the EDGX Book. However, the System does not 
allow the combination of a Discretionary Range and a Post Only 
instruction. Accordingly, the Exchange proposes to re-locate the 
reference to the Discretionary Range instruction within Rule 11.8(b) so 
that it is no longer grouped with other orders that can be combined 
with a Post Only instruction. The Exchange also proposes to state in 
Rule 11.8(b) that: (i) a Limit Order with a Discretionary Range 
instruction may also include a Book Only instruction; and (ii) a Limit 
Order with a Discretionary Range instruction and a Post Only 
instruction will be rejected. Further, the Exchange proposes to refer 
to the ability of a Limit Order to include a Discretionary Range 
instruction, rather than a ``User'' that may include a Discretionary 
Range instruction.
    Second, the Exchange proposes to amend Rule 11.8(b)(10) regarding 
the application of the re-pricing instructions to comply with Rule 610 
of Regulation NMS to Limit Orders. In particular, to align with BZX 
Rule 11.9(g) and EDGA Rule 11.8(b)(10), the Exchange proposes to amend 
the default re-pricing option from Price Adjust to Display-Price 
Sliding, which is the default re-pricing option on BZX and EDGA. As 
amended, a Limit Order that, if displayed at its limit price at the 
time of entry into the System, would become a Locking Quotation or 
Crossing Quotation will be automatically defaulted by the System to the 
Display-Price Sliding instruction, unless the User affirmatively elects 
to have the order immediately Cancel Back or affirmatively elects the 
Price Adjust instruction, rather than the Hide Not Slide instruction, 
as the Hide Not Slide instruction would no longer be available. This 
proposed rule change is designed to update Rule 11.8(b)(10) to reflect 
the proposed replacement of Hide Not Slide with Display-Price Sliding 
under Rule 11.6(l)(1)(B) discussed above. Moreover, the change to 
default orders to the Display-Price Sliding instruction, rather than 
Price Adjust, will enable the Exchange to provide consistent default 
behavior across EDGX, EDGA and BZX.
    Third, the Exchange proposes to amend Rule 11.8(b)(12) regarding 
the re-pricing of orders with a Non-Displayed instruction and orders of 
Odd Lot Size. These changes are intended to reflect the proposed 
amendments to Rule 11.6(l)(3) discussed above. The proposal would 
remove all references to orders of Odd Lot size within Rule 
11.8(b)(12), as orders of Odd Lot size would be treated like orders of 
Round Lot or Mixed Lot size, as currently done on BZX. The proposal 
would also amend Rule 11.8(b)(12) to state that a Limit Order with a 
Non-Displayed instruction which crosses a Protected Quotation of an 
external market, rather than being priced better than the midpoint of 
the

[[Page 43819]]

NBBO, will be re-priced in accordance with the Re-Pricing of orders 
with a Non-Displayed instruction process under Rule 11.6(l)(3). Lastly, 
the Exchange proposes to state that under Rule 11.6(l)(3), a User may 
affirmatively elect that a buy (sell) order with a Non-Displayed 
instruction Cancel Back when the order's limit price would cross a 
Protected Quotation of an external market, rather than when the order's 
limit price is greater (less) than the NBO (NBB). These proposed 
changes are designed to update Rule 11.8(b)(12) to reflect the proposed 
amendment to the re-pricing of orders with a Non-Displayed instruction 
under Rule 11.6(l)(3) discussed above.
    Replacing MPM Orders With MidPoint Peg Order Type (Rule 11.8(d)).
    The Exchange proposes amend Rule 11.8(d) to replace MPM Orders with 
MidPoint Peg Orders to further align the Exchange's System with BZX 
functionality. The operation of the proposed MidPoint Peg Order will be 
identical to the operation of Midpoint Peg Orders on BZX \41\ and 
EDGA.\42\ In sum, an MPM Order is a non-displayed Market Order or Limit 
Order with an instruction to execute only at the midpoint of the NBBO. 
An MPM Order that is entered with a limit price will have its ability 
to execute at the mid-point of the NBBO bound by such limit price. An 
MPM Order will not be eligible for execution when an NBBO is not 
available. In such case, an MPM Order would rest on the EDGX Book and 
would not be eligible for execution in the System until an NBBO is 
available. The MPM Order will receive a new time stamp when an NBBO 
becomes available and a new midpoint of the NBBO is established. In 
such case, pursuant to Rule 11.9, all MPM Orders that are ranked at the 
midpoint of the NBBO will retain their priority as compared to each 
other based upon the time such orders were initially received by the 
System.
---------------------------------------------------------------------------

    \41\ See BZX Rule 11.9(c)(9).
    \42\ See EDGA Rule 11.8(d).
---------------------------------------------------------------------------

    The Exchange proposes to amend Rule 11.8(d) by replacing MPM Orders 
with MidPoint Peg Orders, the operation of which will be identical to 
the operation of Midpoint Peg Orders on BZX \43\ and EDGA.\44\ In 
addition, the proposed rule text for Rule 11.8(d) would be identical to 
EDGA Rule 11.8(d). The main differences between the operation of MPM 
Orders and MidPoint Peg Orders are as follows: (i) Midpoint Peg Order 
will be able to execute at prices equal to or better than the midpoint 
of the NBBO, and not just at the midpoint of the NBBO as is currently 
the case with MPM Orders; and (ii) unlike MPM Orders, MidPoint Peg 
Orders may be coupled with a Post Only instruction. The Exchange 
believes replacing MPM Orders with MidPoint Peg Orders would increase 
liquidity at the midpoint of the NBBO on EDGX, thereby increasing the 
potential for price improvement and improving execution quality on the 
Exchange.
---------------------------------------------------------------------------

    \43\ See BZX Rule 11.9(c)(9).
    \44\ See EDGA Rule 11.8(d).
---------------------------------------------------------------------------

    Exchange Rule 11.8(d) would define a MidPoint Peg Order as a non-
displayed Market Order or Limit Order with an instruction to execute at 
the midpoint of the NBBO, or, alternatively, pegged to the less 
aggressive of the midpoint of the NBBO or one minimum price variation 
inside the same side of the NBBO as the order. A MidPoint Peg Order 
will be ranked at the midpoint of the NBBO where its limit price is 
equal to or more aggressive than the midpoint of the NBBO. Like an MPM 
Order, a MidPoint Peg Order will not be eligible for execution when an 
NBBO is not available. In such case, a MidPoint Peg Order would rest on 
the EDGX Book and would not be eligible for execution in the System 
until an NBBO is available. The MidPoint Peg Order will receive a new 
time stamp when an NBBO becomes available and a new midpoint of the 
NBBO is established. In such case, pursuant to Rule 11.9, all MidPoint 
Peg Orders that are ranked at the midpoint of the NBBO will retain 
their priority as compared to each other based upon the time such 
orders were initially received by the System. A MidPoint Peg Order will 
be ranked at its limit price where its limit price is less aggressive 
than the midpoint of the NBBO. A MidPoint Peg Limit Order may contain 
the following TIF instructions: Day, FOK, IOC, RHO, GTX, or GTD. Any 
unexecuted portion of a MidPoint Peg Limit Order with a TIF instruction 
of Day, GTX, or GTD that is resting on the EDGX Book will receive a new 
time stamp each time it is re-priced in response to changes in the 
midpoint of the NBBO.
    As proposed, a MidPoint Peg Order may include a limit price that 
would specify the highest or lowest prices at which the MidPoint Peg 
Order to buy or sell would be eligible to be executed. Specifically, a 
MidPoint Peg Order with a limit price that is more aggressive than the 
midpoint of the NBBO will execute at the midpoint of the NBBO or better 
subject to its limit price.\45\ For example, assume the NBBO is $10.10 
by $10.18, resulting in a midpoint of $10.14, and there are no orders 
resting on the EDGX Book. An order with a Non-Displayed instruction to 
sell is entered with a limit price of $10.12 and is posted non-
displayed on the EDGX Book. A MidPoint Peg Order to buy with a limit 
price of $10.15 is then entered and executes against the order to sell 
at $10.12, a price better than the midpoint of the NBBO because the 
MidPoint Peg Order is able to receive price improvement subject to its 
limit price. A MidPoint Peg Order will be ranked at the midpoint of the 
NBBO where its limit price is equal to or more aggressive than the 
midpoint of the NBBO.
---------------------------------------------------------------------------

    \45\ A MidPoint Peg Order will execute at prices better than the 
midpoint of the NBBO where it is able to receive price improvement 
subject to its limit price either upon entry or re-pricing.
---------------------------------------------------------------------------

    A MidPoint Peg Order may execute at its limit price or better where 
its limit price is less aggressive than the midpoint of the NBBO. For 
example, assume the NBBO is $10.01 by $10.02, resulting in a midpoint 
of $10.015, and there are no orders resting on the EDGX Book. A 
MidPoint Peg Order to buy is entered with a limit price of $10.01 and 
posted non-displayed on the EDGX Book at $10.01, its limit price, 
because its limit price precludes it from being posted at $10.015, the 
midpoint of the NBBO. An order to sell at $10.01 is then entered and 
executes against the MidPoint Peg Order to buy at $10.01. A MidPoint 
Peg Order will be ranked at its limit price where its limit price is 
less aggressive than the midpoint of the NBBO.
    Like an MPM Order, Proposed Rule 11.8(d) would also state that a 
MidPoint Peg Order may only be entered as an Odd Lot, Round Lot or a 
Mixed Lot. A User may include a Minimum Execution Quantity instruction 
on a MidPoint Peg Order. However, a Minimum Execution Quantity 
instruction will be ignored by the System during Opening Process.\46\ 
MidPoint Peg Orders are not eligible for routing pursuant to Rule 
11.11, unless routed utilizing the RMPT routing strategy as defined in 
proposed renumbered Rule 11.11(g)(13). Unlike MPM Orders, MidPoint Peg 
Orders may be coupled with a Post Only instruction,\47\ in addition to 
a Book Only instruction.
---------------------------------------------------------------------------

    \46\ See Exchange Rule 11.7.
    \47\ The Exchange notes that the execution of an incoming 
MidPoint Peg order with a Post Only instruction will be subject to 
the economic best interest analysis set forth under Rule 11.6(n)(4).
---------------------------------------------------------------------------

    Unless otherwise instructed by the User, a MidPoint Peg Order is 
not eligible for execution when a Locking Quotation exists. All 
Midpoint Peg Orders are not eligible for execution when a Crossing 
Quotation exists. In such cases, a MidPoint Peg Order would

[[Page 43820]]

rest on the EDGX Book and would not be eligible for execution in the 
System until a Locking Quotation or Crossing Quotation no longer 
exists. This behavior is consistent with operation of Mid-Point Peg on 
BZX under BZX Rule 11.9(c)(9).
    MidPoint Peg orders are defaulted by the System to a Non-Displayed 
instruction. MidPoint Peg orders are not eligible to include a 
Displayed instruction. MidPoint Peg Orders may only be executed during 
the Pre-Opening Session, Regular Trading Hours, and the Post-Closing 
Session. Like MPM Orders, MidPoint Peg Orders will not trade with any 
other orders at a price above the Upper Price Band or below the Lower 
Price Band.
Rule 11.9, Priority of Orders
    With respect to the Exchange's priority and execution algorithm, 
the Exchange is proposing various minor and structural to changes based 
on BZX Rule 11.12 that are intended to emphasize the processes by which 
orders are accepted, priced, ranked, displayed and executed, as well as 
a new provision related to the ability of orders to rest at the Locking 
Price and the Exchange's handling of orders in such a circumstance. In 
addition to the changes proposed with respect to Rule 11.9, discussed 
immediately below, these changes also relate to Rules 11.10 and 11.11.
    The Exchange proposes modifications to Rule 11.9, Priority of 
Orders, to make clear that the ranking of orders described in such rule 
is in turn dependent on Exchange rules related to the execution of 
orders, primarily Rule 11.10. The Exchange believes that this has 
always been the case under Exchange rules but there was not previously 
a description of the cross-reference to Rule 11.10 within such rules. 
Accordingly, the Exchange proposes to add reference to the execution 
process in addition to the numeric cross-reference to Rule 11.10.\48\ 
The Exchange also proposes to change certain references within Rule 
11.9 to refer to ranking rather than executing equally priced trading 
interest, as the Rule as a whole is intended to describe the manner in 
which resting orders are ranked and maintained, specifically in price 
and time priority, while awaiting execution against incoming orders. 
The Exchange does not believe that the proposed modifications 
substantively modify the operation of the rules but the Exchange 
believes that it is important to make clear that the ranking of orders 
is a separate process from the execution of orders. The Exchange also 
proposes changes to Rule 11.9(a)(4) and (a)(5) to specify that orders 
retain and lose ``time'' priority under certain circumstances as 
opposed to priority generally because retaining or losing price 
priority does not require the same descriptions, as price priority will 
always be retained unless the price of an order changes. Each change 
proposed above was recently approved with respect to analogous rules of 
BZX and BYX, specifically amendments to Rule 11.12.\49\
---------------------------------------------------------------------------

    \48\ The Exchange notes that it recently filed an immediately 
effective proposal containing marking errors with respect to the 
rule text proposed for sub-paragraphs (a)(2), (a)(2)(A) and 
(a)(2)(B). See Securities Exchange Act Release No. 74023 (January 9, 
2015), 80 FR 2163 (January 15, 2015) (SR-EDGX-2015-03). Accordingly, 
the Exchange has correctly marked the change in connection with this 
proposal.
    \49\ See supra note 11.
---------------------------------------------------------------------------

    As described below, the Exchange also proposes to amend Rule 11.9 
to align with BZX functionality and BZX Rule 11.12 regarding how orders 
with certain instructions are to be ranked by the System: (i) At the 
midpoint of the NBBO under subparagraph (a)(2)(B); and (ii) where buy 
(sell) orders utilize instructions that cause them to be ranked by the 
System upon clearance of a Locking Quotation under subparagraph 
(a)(2)(C).\50\ The Exchange does not propose to amend the ranking of 
orders at a price other than the midpoint of the NBBO under Rule 
11.9(a)(2)(A).
---------------------------------------------------------------------------

    \50\ For purposes of priority under proposed Rule 11.9(a)(2)(A), 
(B) and (C), the Exchange notes that orders of Odd Lot, Round Lot, 
or Mixed Lot size are treated equally.
---------------------------------------------------------------------------

    At the Midpoint of the NBBO. Rule 11.9(a)(2)(B) currently states 
that the System will execute trading interest priced at the midpoint of 
the NBBO within the System in time priority in the following order: (i) 
Limit Orders to which the Hide Not Slide instruction has been applied; 
(ii) MPM Orders; (iii) Limit Orders with a Non-Displayed instruction; 
(iv) Orders with a Pegged instruction; (v) Reserve Quantity of Limit 
Orders; and (vi) Limit Orders executed within their Discretionary 
Range. As amended, the System will rank equally priced trading interest 
in such circumstances in the following order: (i) Limit Orders to which 
the Display-Price Sliding instruction has been applied; (ii) Limit 
Orders with a Non-Displayed instruction; (iii) Orders with a Pegged 
instruction; (iv) MidPoint Peg Orders; (v) Reserve Quantity of Limit 
Orders; and (vi) Limit Orders executed within their Discretionary 
Range.
    Thus, orders will be substantially ranked in same order except 
that, as amended, the rule would be updated to reflect replacing of: 
(i) Hide Not Slide with Display-Price Sliding; and (ii) MPM Order with 
MidPoint Peg orders, which will be placed behind orders with a Pegged 
instruction. The proposed ranking of orders is identical to that set 
forth under BZX Rule 11.12(a)(2), which covers the ranking of orders 
generally, including at the midpoint of the NBBO. The Exchange notes 
that, pursuant to proposed Rule 11.10(a)(4)(D) governing the price at 
which non-displayed locking interest is executable and discussed in 
detail below, the Exchange will execute the incoming order to sell 
(buy) at one-half minimum price variation less (more) than the price of 
the order displayed on the EDGX Book. In such case, an order with a 
Display-Price Sliding instruction resting on the EDGX Book could 
execute against a contra-side order at the midpoint of NBBO and such 
order would be ranked ahead of all other orders ranked at the midpoint 
of the NBBO. The Exchange believes it is reasonable and appropriate to 
grant first priority to Limit Orders subject to the Display-Price 
Sliding instruction because they are displayed on the EDGX Book one 
Minimum Price Variation away from the Locking Price, while other orders 
at the mid-point of the NBBO remain non-displayed.\51\ In equity 
markets generally, displayed orders are traditionally given first 
priority over non-displayed orders due to their contribution to the 
price discovery process.
---------------------------------------------------------------------------

    \51\ Under the proposed amendment to Rule 11.6(l)(1)(B), buy 
(sell) orders subject to the Display-Price Sliding instruction will 
be displayed at a price that is one Minimum Price Variation lower 
(higher) than the Locking Price, will be ranked at the Locking 
Price.
---------------------------------------------------------------------------

    In addition, the Exchange believes it is reasonable and appropriate 
to grant MidPoint Peg Orders priority behind Limit Orders with a Non-
Displayed instruction and orders with a Pegged instruction because 
these order types can provide liquidity on the EDGX Book that is priced 
more aggressively than the NBBO. The Exchange notes that both Limit 
Orders with a Non-Displayed instruction and orders with a Pegged 
instruction are posted to the EDGX Book at a specified price (i.e., a 
limit price or pegged price) that may be more aggressive than the NBBO, 
including bids at the same price as the NBO or offers at the same price 
as the NBB (i.e., fully crossing the spread). Meanwhile, a MidPoint Peg 
Order is posted to the EDGX Book at a non-displayed price, and while 
providing price improving liquidity at the midpoint of the NBBO,

[[Page 43821]]

may not be posted to the EDGX Book at a price level that is more 
aggressive than the NBBO. Thus, MidPoint Peg Orders are guaranteed to 
execute at prices equal to or less aggressive than the midpoint of the 
NBBO. In contrast, Limit Orders with a Non-Displayed instruction and 
orders with a Pegged instruction do not have this same guarantee. 
Therefore, the Exchange believes it is reasonable and appropriate to 
grant MidPoint Peg Orders priority behind Limit Orders with a Non-
Displayed instruction and orders with a Pegged instruction.
    Orders Re-Ranked upon Clearance of a Locking Quotation. The 
Exchange does not propose to make any changes to the ranking of orders 
that are re-ranked upon clearance of a Locking Quotation other than to 
replace a reference to Hide Not Slide with Display-Price Sliding to 
reflect the Exchange proposal to amend Rule 11.6(l)(1)(B) by replacing 
the Hide Not Slide re-pricing instruction with the Display-Price 
Sliding instruction, as described above. The Exchange believes that 
granting second priority to Limit Orders subject to the Display-Price 
Sliding instruction, as is currently provided for orders with a Hide 
Not Slide instruction, is appropriate because prior to the Locking 
Quotation or Crossing Quotation existing, these orders were eligible to 
be executed, Non-Displayed, at the Locking Price. In addition, like 
Hide Not Slide, Limit Orders subject to the Display-Price Sliding 
instruction are more aggressively priced when a Locking Quotation or 
Crossing Quotation does not exist than orders subject to the Price 
Adjust instruction.
Rule 11.10, Order Execution
    The Exchange proposes to adopt paragraph (C) of Rule 11.10(a)(4), 
which would be identical to BZX Rule 11.13(a)(4)(C).\52\ Proposed 
paragraph (C) would provide further clarity regarding the situations 
where orders are not executable, which although covered in other rules 
proposed above and in current rules,\53\ would focus on the incoming 
order on the same side of an order displayed on the EDGX Book rather 
than the resting order that is rendered not executable at a specified 
price because it is opposite such order displayed on the EDGX Book. 
Proposed paragraph (C) would state that, subject to proposed paragraph 
(D), described below, if an incoming order is on the same side of the 
market as an order displayed on the EDGX Book and upon entry would 
execute against contra-side interest at the same price as such 
displayed order, such incoming order will be cancelled or posted to the 
EDGX Book and ranked in accordance with Rule 11.9. The Exchange notes 
that pursuant to the Exchange's current rules, the Exchange suspends 
the discretion of an order subject to the Hide Not Slide instruction 
for so long as a contra-side order that equals the Locking Price is 
displayed by the System on the EDGX Book. The Exchange suspends this 
discretion to avoid an apparent priority issue. In particular, in such 
a situation the Exchange believes a User representing an order that is 
displayed on the Exchange might believe that an incoming order was 
received by the Exchange and then bypassed such displayed order, 
removing some other non-displayed liquidity on the same side of the 
market as such displayed order. Although the Exchange has proposed to 
eliminate the Hide Not Slide instruction and replace it with the 
Display-Price Sliding instruction, as described above, the Exchange 
will continue to suspend the ability of any order to execute at the 
price of a contra-side order with a Displayed instruction, as described 
above.
---------------------------------------------------------------------------

    \52\ See supra note 11.
    \53\ The Exchange notes that consistent with the proposed 
changes to Rules 11.6 and 11.8 described above, based on User 
instructions certain orders are permitted to post and rest on the 
EDGX Book at prices that lock contra-side liquidity, provided, 
however, that the System will never display a Locking Quotation. 
Similar behavior is also in place with respect to the Hide Not Slide 
instruction under current rules, which the Exchange is proposing to 
replace with the Display Price Sliding instruction.
---------------------------------------------------------------------------

    The Exchange also proposes to adopt Rule 11.10(a)(4)(D), which 
would be identical to BZX Rule 11.13(a)(4)(D).\54\ Proposed Rule 
11.10(a)(4)(D) would govern the price at which an order is executable 
when it is not displayed on the Exchange and there is a contra-side 
displayed order at such price. Specifically, for bids or offers equal 
to or greater than $1.00 per share, in the event that an incoming order 
is a Market Order or is a Limit Order priced more aggressively than an 
order displayed on the Exchange, the Exchange will execute the incoming 
order at, in the case of an incoming sell order, one-half minimum price 
variation less than the price of the displayed order, and, in the case 
of an incoming buy order, at one-half minimum price variation more than 
the price of the displayed order. As is true under existing 
functionality, this order handling is inapplicable for bids or offers 
under $1.00 per share.
---------------------------------------------------------------------------

    \54\ See supra note 11.
---------------------------------------------------------------------------

    To demonstrate the operation of this provision, again assume the 
NBBO is $10.10 by $10.11. Assume the Exchange has a posted and 
displayed bid to buy 100 shares of a security priced at $10.10 per 
share and a resting non-displayed bid to buy 100 shares of a security 
priced at $10.11 per share.
     Assume that the next order received by the Exchange is an 
order with a Post Only instruction to sell 100 shares of the security 
priced at $10.11 per share. The order with a Post Only instruction 
would not remove any liquidity upon entry pursuant to the Exchange's 
economic best interest functionality, would post to the EDGX Book and 
would be displayed at $10.11. The display of this order would, in turn, 
make the resting non-displayed bid not executable at $10.11.
     If an incoming offer to sell 100 shares at $10.10 is 
entered into the EDGX Book, the resting non-displayed bid originally 
priced at $10.11 will be executed at $10.105 per share, thus providing 
a half-penny of price improvement as compared to the order's limit 
price of $10.11. The execution at $10.105 per share also provides the 
incoming offer with a half-penny of price improvement as compared to 
its limit price of $10.10. The result would be the same for an incoming 
market order to sell or any other incoming limit order offer priced at 
$10.10 or below, which would execute against the non-displayed bid at a 
price of $10.105 per share. As above, an offer at the full price of the 
resting and displayed $10.11 offer would not execute against the 
resting non-displayed bid, but would instead either cancel or post to 
the EDGX Book behind the original $10.11 offer in priority.
    The Exchange notes that, in addition to the changes described 
above, it is proposing to add descriptive titles to paragraphs (A) and 
(B) of Rule 11.10(a)(4), which describe the process by which executable 
orders are matched within the System. Specifically, so long as it is 
otherwise executable, an incoming order to buy will be automatically 
executed to the extent that it is priced at an amount that equals or 
exceeds any order to sell in the EDGX Book and an incoming order to 
sell will be automatically executed to the extent that it is priced at 
an amount that equals or is less than any other order to buy in the 
EDGX Book. These rules further state that an order to buy shall be 
executed at the price(s) of the lowest order(s) to sell having priority 
in the EDGX Book and an order to sell shall be executed at the price(s) 
of the highest order(s) to buy having priority in the EDGX Book. The 
Exchange emphasizes these current rules only insofar as to highlight 
the interconnected nature of the priority rule. The Exchange also 
proposes to move language contained

[[Page 43822]]

within Rule 11.10(a)(2) to paragraph (a) of the rule such that the 
language is more generally applicable to the rules governing execution 
contained in Rule 11.10(a)(1) through (5). Specifically, the Exchange 
proposes to relocate language stating that any order falling within the 
parameters of the paragraph shall be referred to as ``executable'' and 
that an order will be cancelled back to the User, if based on market 
conditions, User instructions, applicable Exchange Rules and/or the Act 
and the rules and regulations thereunder, such order is not executable, 
cannot be routed to another Trading Center pursuant to Rule 11.11 or 
cannot be posted to the EDGX Book. Each change proposed above was 
recently approved with respect to analogous rules of BZX, specifically 
amendments to Rule 11.13.\55\
---------------------------------------------------------------------------

    \55\ See supra note 11.
---------------------------------------------------------------------------

Rule 11.11, Routing to Away Trading Centers
    The Exchange also proposes to modify paragraph (h) of Rule 11.11 to 
clarify the Exchange's rule regarding the priority of routed orders. 
Paragraph (h) currently sets forth the proposition that a routed order 
does not retain priority on the Exchange while it is being routed to 
other markets. The Exchange believes that its proposed clarification to 
paragraph (h) is appropriate because it more clearly states that a 
routed order is not ranked and maintained in the EDGX Book pursuant to 
Rule 11.9(a), and therefore is not available to execute against 
incoming orders pursuant to Rule 11.10. The change proposed above was 
recently approved with respect to the analogous rule of BZX, 
specifically Rule 11.13, as amended.\56\
---------------------------------------------------------------------------

    \56\ Id.
---------------------------------------------------------------------------

Implementation Date
    The Exchange intends to implement the proposed rule change 
immediately.\57\
---------------------------------------------------------------------------

    \57\ Implementation of the proposed rule change immediately is 
contingent upon the Commission granting a waiver of the 30-day 
operative delay. 17 CFR 240.19b-4(f)(6)(iii).
---------------------------------------------------------------------------

2. Statutory Basis
    The Exchange believes that the proposed rule changes are consistent 
with Section 6(b) of the Act \58\ and further the objectives of Section 
6(b)(5) of the Act \59\ because they are designed to promote just and 
equitable principles of trade, to remove impediments to and perfect the 
mechanism of a free and open market and a national market system, to 
foster cooperation and coordination with persons engaged in 
facilitating transactions in securities, and, in general, to protect 
investors and the public interest. The proposed rule change also is 
designed to support the principles of Section 11A(a)(1) \60\ of the Act 
in that it seeks to assure fair competition among brokers and dealers 
and among exchange markets.

---------------------------------------------------------------------------

    The proposed rule changes are generally intended to better align 
certain Exchange rules and system functionality with that currently 
offered by BZX in order to provide a consistent functionality across 
the Exchange and BZX. Consistent functionality between the Exchange and 
BZX will reduce complexity and streamline duplicative functionality, 
thereby resulting in simpler technology implementation, changes and 
maintenance by Users of the Exchange that are also participants on BZX. 
The proposed rule changes do not propose to implement new or unique 
functionality that has not been previously filed with the Commission or 
is not available on BZX. The Exchange notes that the proposed rule text 
is based on applicable BZX or EDGA rules; the proposed language of the 
Exchange's Rules differs only to extent necessary to conform to 
existing Exchange rule text or to account for details or descriptions 
included in the Exchange's Rules but not in the applicable BZX rule. 
The Exchange believes it is consistent with the Act to maintain its 
current structure and such detail, rather than removing such details 
simply to conform to the structure or format of BZX rules, again 
because the Exchange believes this will increase the understanding of 
the Exchange's operations for all Members of the Exchange. Where 
possible, the Exchange has mirrored BZX rules, because consistent rules 
will simplify the regulatory requirements and increase the 
understanding of the Exchange's operations for Members of the Exchange 
that are also participants on BZX. As such, the proposed rule change 
would foster cooperation and coordination with persons engaged in 
facilitating transactions in securities and would remove impediments to 
and perfect the mechanism of a free and open market and a national 
market system.
    In addition to the specific rules discussed below, the Exchange 
also believes that the proposed amendments to clarify and re-structure 
the Exchange's priority, execution and routing rules will contribute to 
the protection of investors and the public interest by making the 
Exchange's rules easier to understand.
    Definitions (Rule 11.6). The modifications related to Discretionary 
Range, Pegged instructions, Re-Pricing, Aggressive, Super Aggressive, 
Post Only, as well as TIFs of IOC and FOK, are each designed to better 
align certain Exchange rules and system functionality with that 
currently offered by BZX in order to provide a consistent functionality 
across the Exchange and BZX. Specifically, the Exchange believes that 
the proposed rule changes will provide additional clarity and 
specificity regarding the functionality of the System and provide Users 
with consistent rules across the Exchange and BZX, and thus would 
promote just and equitable principles of trade and remove impediments 
to a free and open market.
    In particular, the Exchange believes it is consistent with the Act 
to execute orders with a Discretionary Range instruction and orders 
with a Super Aggressive instruction against marketable liquidity (i.e., 
order with a Post Only instruction) when an execution would not 
otherwise occur is consistent with both: (i) the Act, by facilitating 
executions, removing impediments and perfecting the mechanism of a free 
and open market and national market system; and (ii) a User's 
instructions, which have evidenced a willingness by the User to pay 
applicable execution fees and/or execute at more aggressive prices than 
they are currently ranked in favor of an execution.
    The Exchange also believes that the proposed changes to Rule 
11.6(l) are consistent with Section 6(b)(5) of the Act,\61\ as well as 
Rule 610 of Regulation NMS \62\ and Rule 201 of Regulation SHO.\63\ 
Rule 610(d) requires exchanges to establish, maintain, and enforce 
rules that require members reasonably to avoid ``[d]isplaying 
quotations that lock or cross any protected quotation in an NMS 
stock.'' \64\ Such rules must be ``reasonably designed to assure the 
reconciliation of locked or crossed quotations in an NMS stock,'' and 
must ``prohibit . . . members from engaging in a pattern or practice of 
displaying quotations that lock or cross any quotation in an NMS 
stock.'' \65\ This change will provide additional specificity within 
the Exchange's rules regarding the availability of the Price Adjust 
instruction as well as align the description with BZX's Price Adjust 
process described under BZX Rule

[[Page 43823]]

11.9(g)(2) and display price sliding process described under BZX Rule 
11.9(g)(1).

---------------------------------------------------------------------------

    In addition, Rule 201 of Regulation SHO \66\ requires trading 
centers to establish, maintain, and enforce written policies and 
procedures reasonably designed to prevent the execution or display of a 
short sale order at a price at or below the current NBB under certain 
circumstances. The proposed amendments to the Re-Pricing Instructions 
to Comply with Rule 201 of Regulation SHO are similar to approved BZX 
rules and will provide Users with a consistent handling of their orders 
in such circumstances across the Exchange and BZX.
---------------------------------------------------------------------------

    \66\ 17 CFR 242.201.
---------------------------------------------------------------------------

    The Exchange believes that the proposed replacement of the Hide Not 
Slide instruction with the Display-Price Sliding instruction is 
consistent with Section 6(b)(5) of the Act,\67\ as well as Rule 610 of 
Regulation NMS.\68\ The proposed Display-Price Sliding instruction 
would operate in an identical fashion to the Display-Price Sliding 
process currently available on BZX and described under BZX Rule 
11.9(g)(1).\69\ As mentioned above, Rule 610(d) of Regulation NMS 
requires exchanges to establish, maintain, and enforce rules that 
require members reasonably to avoid ``[d]isplaying quotations that lock 
or cross any protected quotation in an NMS stock.'' \70\ Such rules 
must be ``reasonably designed to assure the reconciliation of locked or 
crossed quotations in an NMS stock,'' and must ``prohibit . . . members 
from engaging in a pattern or practice of displaying quotations that 
lock or cross any quotation in an NMS stock.'' \71\ Thus, the Display-
Price Sliding instruction proposed to be offered by the Exchange will 
assists Users by displaying orders at permissible prices, thereby 
promoting just and equitable principles of trade, removing impediments 
to, and perfects the mechanism of, a free and open market and a 
national market system.

---------------------------------------------------------------------------

    The Exchange believes that the proposed changes to its re-pricing 
of orders with a Non-Displayed instruction or of Odd Lot size is 
consistent with Section 6(b)(5) of the Act.\72\ The proposed changes to 
Rule 11.6(l)(3) are based on BZX Rule 11.9(g)(4) and will provide Users 
with consistent handing of their orders in such circumstances across 
the Exchange and BZX. The Exchange also believes it is reasonable to 
remove references to orders of Odd Lot size from the Exchange's Rules 
regarding re-pricing, as those orders would no longer be re-priced like 
orders with a Non-Displayed instruction and will be treated like orders 
of Round Lot or Mixed Lot size, as currently done on BZX. Therefore, 
the Exchange believes the proposed changes to the re-pricing of order 
with a Non-Displayed instruction will continue to promote just and 
equitable principles of trade, removes impediments to, and perfects the 
mechanism of, a free and open market and a national market system.
---------------------------------------------------------------------------

    \72\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    Order Types (Rule 11.8). The Exchange believes that the proposed 
changes to its order types under Rule 11.8 are consistent with Section 
6(b)(5) of the Act,\73\ because they are intended to align their 
operation with the operation of identical order types on BZX, thereby 
fostering cooperation and coordination with persons engaged in 
facilitating transactions in securities and removing impediments to and 
perfecting the mechanism of a free and open market and a national 
market system.
---------------------------------------------------------------------------

    \73\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The Exchange believes its proposed amendments to the description of 
Limit Orders under Rule 11.8(b) is reasonable because it aligns their 
operation with existing BZX rules and functionality as well as to 
reflect the relevant proposed changes discussed above. The Exchange 
also believes it is reasonable to default orders to the Display-Price 
Sliding instruction, rather than Price Adjust, as it would enable the 
Exchange to provide consistent default behavior across EDGX, EDGA and 
BZX. On EDGA and BZX, orders also default to the respective display-
price sliding processes, which operate in an identical manner as the 
proposed Display-Price Sliding instruction. Therefore, the proposed 
rule change promotes just and equitable principles of trade because it 
will avoid investor confusion by providing the identical default 
behavior across the Exchange, EDGA and BZX.
    In addition, the Exchange believes its proposal to amend Rule 
11.8(d) to replace the MPM order type with Market Peg order type is 
consistent with the Act because the MidPoint Peg Order would operate in 
the same fashion as identical order types available on EDGA and BZX, 
thereby further aligning functionality across the BGM Affiliated 
Exchanges. The Exchange believes replacing MPM Orders with MidPoint Peg 
Orders would increase liquidity at the midpoint of the NBBO on EDGX, 
thereby improving both the potential for price improvement and 
execution quality on the Exchange. For the reasons set forth above, the 
Exchange believes the proposal to replace MPM Order with MidPoint Peg 
Orders would promote just and equitable principles of trade, remove 
impediments to, and perfect the mechanism of, a free and open market 
and a national market system.
    Priority (Rule 11.9). The Exchange believes its proposed amendments 
to Rule 11.9 regarding the priority of orders promotes just and 
equitable principles of trade, remove impediments to, and perfect the 
mechanism of, a free and open market and a national market system by 
providing Members, Users, and the investing public with greater 
transparency regarding how the System operates. The Exchange proposes 
to amend Rule 11.9 to align with BZX functionality and BZX Rules 11.12 
regarding how orders with certain instructions are to be ranked by the 
System: (i) At the midpoint of the NBBO; and (ii) where orders utilize 
instructions that cause them to be ranked by the System upon clearance 
of a Locking Quotation providing valuable, clear information to 
Members, Users, and the investing public on how their orders would be 
executed. As amended, orders will be substantially ranked in same order 
at the midpoint of the NBBO as under current rules except that the rule 
would be updated to reflect replacing of: (i) Hide Not Slide with 
Display-Price Sliding; and (ii) MPM Order with MidPoint Peg Orders, 
which will be placed behind orders with a Pegged instruction. The 
Exchange believes it is reasonable and appropriate to grant first 
priority to Limit Orders subject to the Display-Price Sliding 
instruction because they are displayed on the EDGX Book one Minimum 
Price Variation away from the Locking Price, while other orders at the 
mid-point of the NBBO remain non-displayed.\74\ In equity markets 
generally, displayed orders are traditionally given first priority over 
non-displayed orders due to their contribution to the price discovery 
process.
---------------------------------------------------------------------------

    \74\ Under the proposed amendment to Rule 11.6(l)(1)(B), buy 
(sell) orders subject to the Display-Price Sliding instruction will 
be displayed at a price that is one Minimum Price Variation lower 
(higher) than the Locking Price, will be ranked at the Locking 
Price.
---------------------------------------------------------------------------

    The Exchange notes that it does not propose to make any changes to 
the ranking of orders that are re-ranked upon clearance of a Locking 
Quotation other than to replace a reference to Hide Not Slide with 
Display-Price Sliding. This change is necessary to reflect the

[[Page 43824]]

Exchange's proposal to replace the Hide Not Slide re-pricing 
instruction with the Display-Price Sliding instruction under Rule 
11.6(l)(1)(B), as described above. The Exchange believes that granting 
second priority to Limit Orders subject to the Display-Price Sliding 
instruction, like as is currently provided for orders with a Hide Not 
Slide instruction, is appropriate because prior to the Locking 
Quotation or Crossing Quotation existing, these orders were eligible to 
be executed, Non-Displayed, at the Locking Price. In addition, like 
Hide Not Slide, Limit Orders subject to the Display-Price Sliding 
instruction are more aggressively priced when a Locking Quotation or 
Crossing Quotation does not exist than orders subject to the Price 
Adjust instruction. These changes are made to align Exchange Rule 11.9 
with the functionality set forth in BATS Rule 11.12, as described 
above. The Exchange believes that the proposed rule changes regarding 
order priority will continue to provide greater transparency and 
further clarity on how the various order types will be assigned 
priority under various scenarios, thereby assisting Members, Users and 
the investing public in understanding the manner in which the System 
may execute their orders.
    Order Execution (Rule 11.10). Proposed Rule 11.10(a)(4)(C), which 
would be identical to BZX Rule 11.13(a)(4)(C),\75\ is consistent with 
Rules 11.6 and 11.8, as proposed to be amended, and reflects the fact 
that the Exchange will suspend the ability of an order to execute at 
the Locking Price when there is a contra-side order with a Displayed 
instruction in order to avoid an apparent priority issue. In turn, the 
Exchange believes that adopting Rule 11.10(a)(4)(C) promotes just and 
equitable principles of trade, fosters cooperation and coordination 
with persons engaged in facilitating transactions in securities, and 
removes impediments to, and perfects the mechanism of, a free and open 
market and a national market system, both with respect to the 
functionality that prevents executions in such a circumstance and with 
respect to the addition of the rule text, because it makes clear to 
Users the operation of the Exchange in conjunction with the proposed 
changes to the System. The Exchange also believes its proposal to adopt 
Rule 11.10(a)(4)(D), which would be identical to BZX Rule 
11.13(a)(4)(D),\76\ promotes just and equitable principles of trade, 
fosters cooperation and coordination with persons engaged in 
facilitating transactions in securities, and removes impediments to, 
and perfects the mechanism of, a free and open market and a national 
market system. The proposed change is based on BZX Rule 11.13(a)(4)(D) 
and sets forth how marketable orders that would otherwise not be 
executed under specific scenarios will be executed, thereby improving 
execution quality for participants sending orders to the Exchange. 
Further, the proposed change will help to provide price improvement to 
market participants, again, in scenarios that at times, such 
participants would potentially not receive executions on the Exchange. 
Thus, the Exchange believes that its proposed order handling process in 
the scenario described in this filing will benefit market participants 
and their customers by allowing them greater flexibility in their 
efforts to fill orders and minimize trading costs. The proposed rule 
change will also provide consistent handling for orders in such 
scenarios across the Exchange and BZX, thereby avoiding investor 
confusion and promoting just and equitable principles of trade.

(B) Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
result in any burden on competition that is not necessary or 
appropriate in furtherance of the purposes of the Act. The Exchange 
notes that the proposal will provide consistent functionality between 
the Exchange and BZX, thereby reducing complexity and streamlining 
duplicative functionality, resulting in simpler technology 
implementation, changes and maintenance by Users of the Exchange that 
are also participants on BZX. Thus, the Exchange believes this proposed 
rule change is necessary to permit fair competition among national 
securities exchanges. In addition, the Exchange believes the proposed 
rule change will benefit Exchange participants in that it is designed 
to achieve a consistent technology offering by the BGM Affiliated 
Exchanges.

(C) Self-Regulatory Organization's Statement on Comments on the 
Proposed Rule Change Received From Members, Participants or Others

    The Exchange has neither solicited nor received written comments on 
the proposed rule change.

III. Date of Effectiveness of the Proposed Rule Change and Timing for 
Commission Action

    Because the proposed rule change does not (i) significantly affect 
the protection of investors or the public interest; (ii) impose any 
significant burden on competition; and (iii) become operative for 30 
days from the date on which it was filed, or such shorter time as the 
Commission may designate, the proposed rule change has become effective 
pursuant to Section 19(b)(3)(A) of the Act and Rule 19b-4(f)(6) 
thereunder.\77\
---------------------------------------------------------------------------

    \77\ In addition, Rule 19b-4(f)(6)(iii) requires the Exchange to 
give the Commission written notice of the Exchange's intent to file 
the proposed rule change, along with a brief description and text of 
the proposed rule change, at least five business days prior to the 
date of filing of the proposed rule change, or such shorter time as 
designated by the Commission. The Exchange has satisfied this 
requirement.
---------------------------------------------------------------------------

    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the 
Act normally does not become operative for 30 days after the date of 
its filing. However, Rule 19b-4(f)(6)(iii) permits the Commission to 
designate a shorter time if such action is consistent with the 
protection of investors and the public interest. The Exchange has asked 
the Commission to waive the 30-day operative delay so that the proposal 
may become operative immediately upon filing. Waiver of the 30-day 
operative delay would permit the Exchange to harmonize its rules across 
BZX and the Exchange in a timely manner, thereby simplifying the rules 
available to Members of the Exchange that are also participants on BZX. 
The Exchange has alerted Members of the technology changes as well as 
its anticipated time line so that Members may make the requisite system 
changes. In addition, the Exchange has conducted several testing 
opportunities for Members to ensure both the Member's and the 
Exchange's systems will operate in accordance with the proposed rule 
change. Based on the foregoing, the Commission believes the waiver of 
the operative delay is consistent with the protection of investors and 
the public interest.\78\ The Commission hereby grants the waiver and 
designates the proposal operative upon filing.
---------------------------------------------------------------------------

    \78\ For purposes only of waiving the 30-day operative delay, 
the Commission has also considered the proposed rule's impact on 
efficiency, competition, and capital formation. See 15 U.S.C. 
78c(f).
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule 
change, the Commission summarily may temporarily suspend such rule 
change if it appears to the Commission that such action is necessary or 
appropriate in the public interest, for the protection of investors, or 
otherwise in furtherance of the purposes of the Act. If the Commission 
takes such action, the Commission shall institute proceedings

[[Page 43825]]

to determine whether the proposed rule should be approved or 
disapproved.
