SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-80768; File No. SR-MIAX-2017-19]


Self-Regulatory Organizations; Miami International Securities 
Exchange LLC; Notice of Filing of a Proposed Rule Change To Amend MIAX 
Options Rules 515, Execution of Orders and Quotes; 515A, MIAX Price 
Improvement Mechanism (``PRIME'') and PRIME Solicitation Mechanism; and 
518, Complex Orders

May 25, 2017.
    Pursuant to the provisions of Section 19(b)(1) of the Securities 
Exchange Act of 1934 (``Act'') \1\ and Rule 19b-4 thereunder,\2\ notice 
is hereby given that on May 12, 2017, Miami International Securities 
Exchange, LLC (``MIAX Options'' or ``Exchange'') filed with the 
Securities and Exchange Commission (``Commission'') a proposed rule 
change as described in Items I, II, and III below, which Items have 
been prepared by the Exchange. The Commission is

[[Page 25348]]

publishing this notice to solicit comments on the proposed rule change 
from interested persons.
---------------------------------------------------------------------------

    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    The Exchange is filing a proposal to amend Exchange Rules 515, 
Execution of Orders and Quotes; 515A, MIAX Price Improvement Mechanism 
(``PRIME'') and PRIME Solicitation Mechanism; and 518, Complex Orders.
    The text of the proposed rule change is available on the Exchange's 
Web site at http://www.miaxoptions.com/rule-filings, at MIAX's 
principal office, 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 aspects of such 
statements.

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

1. Purpose
    The Exchange proposes to amend Exchange Rules 515, Execution of 
Orders and Quotes; 515A, MIAX Price Improvement Mechanism (``PRIME'') 
and PRIME Solicitation Mechanism; and 518, Complex Orders, to establish 
three new types of complex orders,\3\ and to adopt new provisions that 
relate to the processing of those new complex order types. In 
particular, the Exchange is proposing to modify those rules to permit 
the entry and execution of Complex Customer Cross (``cC2C'') Orders, 
Complex Qualified Contingent Cross (``cQCC'') Orders, and Complex PRIME 
(``cPRIME'') Orders, each as discussed more fully below.
---------------------------------------------------------------------------

    \3\ For a description of the trading of complex orders on the 
Exchange, see Exchange Rule 518. See also, Securities Exchange Act 
Release No. 79072 (October 7, 2016), 81 FR 71131 (October 14, 2016) 
(SR-MIAX-2016-26).
---------------------------------------------------------------------------

Background
    Exchange Rule 515(h) currently permits the entry and execution of 
Customer Cross Orders \4\ and Qualified Contingent Cross (``QCC'') 
Orders \5\ in the Exchange's simple market. A Customer Cross Order is 
comprised of a Priority Customer \6\ Order to buy and a Priority 
Customer Order to sell at the same price and for the same quantity. A 
Customer Cross Order is not valid during the opening rotation process 
described in Rule 503.\7\ A QCC Order is comprised of an originating 
order to buy or sell at least 1,000 contracts, or 10,000 mini-option 
contracts, that is identified as being part of a qualified contingent 
trade,\8\ as that term is defined in Rule 516, Interpretations and 
Policies .01, coupled with a contra-side order or orders totaling an 
equal number of contracts. A QCC Order is not valid during the opening 
rotation process described in Rule 503.\9\
---------------------------------------------------------------------------

    \4\ See Exchange Rule 515(h)(1).
    \5\ See Exchange Rule 515(h)(2).
    \6\ The term ``Priority Customer'' means a person or entity that 
(i) is not a broker or dealer in securities, and (ii) does not place 
more than 390 orders in listed options per day on average during a 
calendar month for its own beneficial account(s). See Exchange Rule 
100.
    \7\ See Exchange Rule 516(i).
    \8\ A ``qualified contingent trade'' is a transaction consisting 
of two or more component orders, executed as agent or principal, 
where: (a) At least one component is an NMS Stock, as defined in 
Rule 600 of Regulation NMS under the Act; (b) all components are 
effected with a product or price contingency that either has been 
agreed to by all the respective counterparties or arranged for by a 
broker-dealer as principal or agent; (c) the execution of one 
component is contingent upon the execution of all other components 
at or near the same time; (d) the specific relationship between the 
component orders (e.g., the spread between the prices of the 
component orders) is determined by the time the contingent order is 
placed; (e) the component orders bear a derivative relationship to 
one another, represent different classes of shares of the same 
issuer, or involve the securities of participants in mergers or with 
intentions to merge that have been announced or cancelled; and (f) 
the transaction is fully hedged (without regard to any prior 
existing position) as a result of other components of the contingent 
trade. See Exchange Rule 516, Interpretations and Policies .01.
    \9\ See Exchange Rule 516(j).
---------------------------------------------------------------------------

    Customer Cross Orders and QCC Orders are processed in a crossing 
mechanism of the Exchange's System \10\ designed specifically for the 
execution of those order types, and Rule 515(h) contains order 
processing and execution requirements that are unique to these order 
types. The Exchange proposes to use that same crossing mechanism for 
the processing and execution of cC2C Orders and cQCC Orders. 
Accordingly, the Exchange is proposing to modify Rule 515(h) so that it 
also permits the execution of cC2C Orders and cQCC Orders, through the 
adoption of Rule 515(h)(3) (relating to cC2C Orders) and Rule 515(h)(4) 
(relating to cQCC Orders). Rules 515(h)(3) and (4) include processing 
and execution requirements for cC2C Orders and cQCC Orders that differ 
from the processing and execution requirements under 515(h)(1) and (2) 
for Customer Cross Orders and QCC Orders, respectively.
---------------------------------------------------------------------------

    \10\ The term ``System'' means the automated trading system used 
by the Exchange for the trading of securities. See Exchange Rule 
100.
---------------------------------------------------------------------------

    Exchange Rule 515A currently permits the entry and execution of 
PRIME Orders \11\ and PRIME Solicitation Orders \12\ in the Exchange's 
simple market. PRIME is a price-improvement mechanism of the Exchange's 
System pursuant to which a Member \13\ (``Initiating Member'') 
electronically submits an order that it represents as agent (an 
``Agency Order'') into a PRIME Auction (``Auction''). The Initiating 
Member, in submitting an Agency Order, must be willing to either (i) 
cross the Agency Order at a single price (a ``single-price 
submission'') against principal or solicited interest, or (ii) 
automatically match (``auto-match''), against principal or solicited 
interest, the price and size of responses to a Request for Response 
(``RFR'') that is broadcast to MIAX Options participants up to an 
optional designated limit price.\14\
---------------------------------------------------------------------------

    \11\ See Exchange Rule 515A(a).
    \12\ See Exchange Rule 515A(b).
    \13\ The term ``Member'' means an individual or organization 
approved to exercise the trading rights associated with a Trading 
Permit. Members are deemed ``members'' under the Act. See Exchange 
Rule 100.
    \14\ See Exchange Rule 515A(a)(2)(i). When the Exchange receives 
a properly designated Agency Order for auction processing, an RFR 
detailing the option, side, size, and initiating price will be sent 
to all subscribers of the Exchange's data feeds. The RFR currently 
lasts for 500 milliseconds. Members may submit responses to the RFR 
(specifying prices and sizes). RFR responses shall be an Auction or 
Cancel (``AOC'') order or an AOC eQuote. Such responses cannot cross 
the disseminated MIAX Best Bid or Offer (``MBBO'') on the opposite 
side of the market from the response.
---------------------------------------------------------------------------

    PRIME Orders are processed in the PRIME mechanism of the Exchange's 
System that is designed specifically for the execution of those order 
types. Accordingly, Rule 515A contains order processing and execution 
requirements that are unique to these order types. The Exchange 
proposes to utilize that same PRIME mechanism for the processing and 
execution of cPRIME Orders. Accordingly, the Exchange is proposing to 
modify Rule 515A so that it also permits the execution of cPRIME 
Orders, through certain modifications to Rule 515A(a) and the adoption 
of Interpretations and Policies .12 (PRIME for Complex Orders). 
Interpretations and Policies .12 includes processing and execution 
requirements for cPRIME Orders that differ from the processing

[[Page 25349]]

and execution requirements under 515A(a) for simple PRIME Orders.
    The Exchange is also proposing to amend Exchange Rule 518, which 
governs the processing and execution of complex orders on the Exchange. 
In particular, Rule 518(b) lists and defines complex order types that 
are available for trading on the Exchange.\15\ Accordingly, the 
Exchange proposes to amend Rule 518(b) to list and define the three new 
complex order types: cC2C, cQCC, and cPRIME.
---------------------------------------------------------------------------

    \15\ Exchange Rule 518(b), Types of Complex Orders, lists the 
various complex orders available for trading on the Exchange. The 
Exchange is proposing to add two new complex order types, cC2C and 
cQCC Orders, to this rule.
---------------------------------------------------------------------------

cC2C Orders
    As discussed above, the Exchange proposes to use the same crossing 
mechanism for the processing and execution of cC2C Orders that is used 
for Customer Cross Orders in the simple market. Accordingly, proposed 
Rule 515(h)(3) shall govern the trading of cC2C Orders, as defined in 
Rule 518(b)(5), on MIAX Options.
    Proposed Rule 518(b)(5) defines a cC2C Order as a type of complex 
order which is comprised of one Priority Customer complex order to buy 
and one Priority Customer complex order to sell (the same strategy) at 
the same price (which must be better than (inside) the icMBBO \16\ or 
the best net price of the complex order on the Strategy Book \17\ for 
the strategy, whichever is more aggressive) and for the same quantity.
---------------------------------------------------------------------------

    \16\ The Implied Complex MIAX Best Bid or Offer (``icMBBO'') is 
a calculation that uses the best price from the Simple Order Book 
(defined below) for each component of a complex strategy including 
displayed and non-displayed trading interest. For stock-option 
orders, the icMBBO for a complex strategy will be calculated using 
the best price (whether displayed or non-displayed) on the Simple 
Order Book (defined below) in the individual option component(s), 
and the NBBO in the stock component. See Exchange Rule 518(a)(11).
    \17\ The ``Strategy Book'' is the Exchange's electronic book of 
complex orders and complex quotes. See Exchange Rule 518(a)(17).
---------------------------------------------------------------------------

    Proposed Rule 515(h)(3) describes the execution price requirements 
that are specific for cC2C Orders. Specifically, cC2C Orders are 
automatically executed upon entry provided that the execution is at 
least $0.01 better than (inside) the icMBBO (as defined in Rule 
518(a)(11)) price or the best net price of a complex order (as defined 
in Rule 518(a)(5)) on the Strategy Book (as defined in Rule 
518(a)(17)), whichever is more aggressive (i.e., the higher bid and/or 
lower offer). The purpose of the requirement that the execution be at 
the more aggressive price of either the icMBBO or the best net price of 
the complex order on the Strategy Book is to ensure that each 
participant in the complex order receives a better price than it would 
receive if submitted as a single complex order, and to ensure that 
there is no interference between the simple and complex markets.
    The System will reject a cC2C Order if, at the time of receipt of 
the cC2C Order, (i) the strategy is subject to a cPRIME Auction 
pursuant to Rule 515A proposed Interpretations and Policies .12, or to 
a Complex Auction pursuant to Rule 518(d); or (ii) any component of the 
strategy is subject to a SMAT Event as described in Rule 
518(a)(16).\18\ The purpose of this provision is to maintain an orderly 
market by avoiding the execution of cC2C Orders with components that 
are involved in other System functions (specifically a PRIME Auction, 
Route Timer, or liquidity refresh pause) that could affect the 
execution price of the cC2C Order, and by avoiding concurrent 
processing on the Exchange involving the same security. This 
methodology for the handling of cC2C Orders differs somewhat from the 
methodology for handling Customer Cross Orders, wherein the System will 
not reject a cC2C Order when a component of the strategy is subject to 
the managed interest process \19\ pursuant to Rule 515(c) (as the 
System would reject a Customer Cross Order in the simple market during 
such a condition). A cC2C Order already has a guaranteed execution 
price at the better of $0.01 inside the icMBBO price or at the best net 
price of a complex order on the Strategy Book. Therefore, it is not 
necessary or desirable to reject and thereby preclude the execution of 
a cC2C Order in this circumstance.
---------------------------------------------------------------------------

    \18\ A Simple Market Auction or Timer, or ``SMAT'' Event, is 
defined as any of the following: (i) A PRIME Auction (pursuant to 
Rule 515A); (ii) a Route Timer (pursuant to Rule 529); or (iii) a 
liquidity refresh pause (pursuant to Rule 515(c)(2)). See Exchange 
Rule 518(a)(16).
    \19\ Under the managed interest process, if the limit price of a 
non-routable order locks or crosses the current opposite side NBBO, 
the System will display the order one Minimum Price Variation away 
from the current opposite side NBBO, and book the order at a price 
that will lock the current opposite side NBBO. See Exchange Rule 
515(c)(ii).
---------------------------------------------------------------------------

    Proposed Rule 515(h)(3)(A) states that cC2C Orders will be 
automatically cancelled if they cannot be executed. Proposed Rule 
515(h)(3)(B) provides that cC2C Orders may only be entered in the 
minimum trading increments applicable to complex orders under Rule 
518(c)(1)(i).\20\
---------------------------------------------------------------------------

    \20\ Bids and offers on complex orders and quotes may be 
expressed in $0.01 increments, and the component(s) of a complex 
order may be executed in $0.01 increments, regardless of the minimum 
increments otherwise applicable to individual components of the 
complex order. See Exchange Rule 518(c)(1)(i).
---------------------------------------------------------------------------

    As a regulatory matter, proposed Rule 515(h)(3)(C) states that Rule 
520, Interpretations and Policies .01 \21\ applies to the entry and 
execution of cC2C Orders.
---------------------------------------------------------------------------

    \21\ Rule 520(b) prevents an Electronic Exchange Member from 
executing agency orders to increase its economic gain from trading 
against the order without first giving other trading interest on the 
Exchange an opportunity to either trade with the agency order or to 
trade at the execution price when the Member was already bidding or 
offering on the Book. However, the Exchange recognizes that it may 
be possible for an Electronic Exchange Member to establish a 
relationship with a customer or other person (including affiliates) 
to deny agency orders the opportunity to interact on the Exchange 
and to realize similar economic benefits as it would achieve by 
executing agency orders as principal. It will be a violation of Rule 
520(b) for an Electronic Exchange Member to be a party to any 
arrangement designed to circumvent Rule 520(b) by providing an 
opportunity for a customer or other person (including affiliates) to 
regularly execute against agency orders handled by the Electronic 
Exchange Member immediately upon their entry into the System. See 
Exchange Rule 520, Interpretations and Policies .01.
---------------------------------------------------------------------------

    Proposed Rule 515(h)(3)(D) states that the Exchange will determine, 
on a class-by-class basis, the option classes in which cC2C Orders are 
available for trading on the Exchange, and will announce such classes 
to Members via Regulatory Circular.
    The following example illustrates the execution of a cC2C Order:
Example 1--A cC2C Order Is Executed
MIAX-LMM Mar 50 Call 6.00-6.50 (10x10)
MIAX-LMM Mar 55 Call 3.00-3.30 (10x10)

Strategy: Buy 1 Mar 50 Call, Sell 1 Mar 55 Call

The icMBBO is 2.70 debit bid at 3.50 credit offer
The dcMBBO is 2.70 debit bid at 3.50 credit offer

    The Strategy Book contains a Priority Customer offer to sell the 
Strategy at 3.30 credit, 20 times.
    The Exchange receives a cC2C Order representing Priority Customers 
on both sides for the simultaneous purchase and sale of the strategy at 
a net price of 3.29, 500 times.
    Since the order price is at least $0.01 better than (inside) the 
icMBBO and the best net price of any order for the Strategy on the 
Strategy Book, the cC2C order is automatically executed upon entry.
cQCC Orders
    As discussed above, the Exchange proposes to use the same crossing 
mechanism for the processing and execution of cQCC Orders that is used

[[Page 25350]]

for QCC Orders in the simple market.\22\ Accordingly, proposed Rule 
515(h)(4) shall govern the trading of cQCC Orders, as defined in Rule 
518(b)(6), on MIAX Options.
---------------------------------------------------------------------------

    \22\ See Exchange Rule 515(h)(2).
---------------------------------------------------------------------------

    Proposed Rule 518(b)(6) defines a cQCC Order as a type of complex 
order which is comprised of a complex order to buy or sell where each 
component is at least 1,000 contracts that is identified as being part 
of a qualified contingent trade, as defined in Rule 516, 
Interpretations and Policies .01,\23\ coupled with a contra-side 
complex order or orders (for the same strategy) totaling an equal 
number of contracts.
---------------------------------------------------------------------------

    \23\ See supra note 8.
---------------------------------------------------------------------------

    Proposed Rule 515(h)(4) mirrors the execution price requirements 
for simple QCC Orders by providing that cQCC Orders are automatically 
executed upon entry provided that, with respect to each option leg of 
the cQCC Order, the execution (i) is not at the same price as a 
Priority Customer Order on the Exchange's Book; \24\ and (ii) is at or 
between the NBBO. The purpose of the requirement that each option leg 
be executed at or between the NBBO is to ensure that no option 
component of the cQCC Order trades through the NBBO. The purpose of the 
requirement that each option leg be executed at a price better than any 
Priority Customer on the Book is to ensure that no option component of 
the cQCC Order trades ahead of a Priority Customer Order.
---------------------------------------------------------------------------

    \24\ The term ``Book'' means the electronic book of buy and sell 
orders and quotes maintained by the System. See Exchange Rule 100.
---------------------------------------------------------------------------

    The Options Order Protection and Locked/Crossed Markets Plan (the 
``Plan''), provides an exception to the requirement that Participants 
establish, maintain and enforce written policies and procedures that 
are reasonably designed to prevent Trade-Throughs when the transaction 
that constituted the Trade-Through was effected as a portion of a 
``complex trade,'' as defined in the rules of a Participant.\25\
---------------------------------------------------------------------------

    \25\ See Section 5(b)(viii) of the Plan. See also, Exchange Rule 
1401(b)(7).
---------------------------------------------------------------------------

    The System does not consider the NBBO price for the stock component 
because the Exchange does not execute the stock component; the Exchange 
executes the option components at a net price and ensures that the 
execution price of each option component of the strategy is (i) not at 
the same price as a Priority Customer Order on the Exchange's Simple 
Order Book; \26\ and (ii) at or between the NBBO. The Exchange does 
require that the Member entering a QCC Order provide certain 
information to the Exchange regarding the execution of the stock 
component, such as the underlying price, quantity, price delta, 
execution time and executing venue.\27\ The Exchange will require this 
same information from Members with respect to cQCC Orders.
---------------------------------------------------------------------------

    \26\ The ``Simple Order Book'' is the Exchange's regular 
electronic book of orders and quotes, as defined in Exchange Rule 
518, Complex Orders. See Exchange Rule 518(a)(15). For purposes of 
the instant proposed rule change, the terms ``Book'' (see supra note 
24) and ``Simple Order Book'' have the same meaning and are 
interchangeable.
    \27\ See MIAX Options Regulatory Circular No. 2015-47 (October 
2, 2015), describing Regulatory Requirements when entering a 
Qualified Contingent Cross Order.
---------------------------------------------------------------------------

    This complex pricing requirement aligns with the simple order 
pricing requirement for a Qualified Contingent Trade (``QCT'') to 
consider the NBBO price. In each case, the parties to a contingent 
trade are focused on the spread or ratio between the transaction prices 
for each of the component instruments (i.e., the net price of the 
entire contingent trade), rather than on the absolute price of any 
single component. Pursuant to the requirements of the NMS QCT 
Exemption, the spread or ratio between the relevant instruments must be 
determined at the time the order is placed, and this spread or ratio 
stands regardless of the market prices of the individual orders at 
their time of execution. As the Commission noted in the Original QCT 
Exemption, ``the difficulty of maintaining a hedge, and the risk of 
falling out of hedge, could dissuade participants from engaging in 
contingent trades, or at least raise the cost of such trades.'' Thus, 
the Commission found that, if each stock leg of a qualified contingent 
trade were required to meet the trade-through provisions of Rule 611 of 
Regulation NMS, such trades could become too risky and costly to be 
employed successfully and noted that the elimination or reduction of 
this trading strategy potentially could remove liquidity from the 
market.\28\ This is also true for QCC Orders in options, and thus the 
Exchange believes that its proposal is consistent with the Original QCT 
Exemption.
---------------------------------------------------------------------------

    \28\ See Securities Exchange Act Release No. 54389 (August 31, 
2006), 71 FR 52829 (September 7, 2006) (``Original QCT Exemption'').
---------------------------------------------------------------------------

    The System will reject a cQCC Order if, at the time of receipt of 
the cQCC Order, (i) the strategy is subject to a cPRIME Auction 
pursuant to proposed Rule 515A, Interpretations and Policies .12, or to 
a Complex Auction pursuant to Rule 518(d); or any component of the 
strategy is subject to a SMAT Event as described in Rule 
518(a)(16).\29\ This provision is intended to maintain an orderly 
market by avoiding the execution of cQCC Orders with components that 
are involved in other System functions (specifically a PRIME Auction, 
Route Timer, or liquidity refresh pause) that could affect the 
execution price of the cQCC Order, and by avoiding concurrent 
processing on the Exchange involving the same security. For the same 
reasons as described above with respect to cC2C Orders, the System will 
not reject a cQCC Order when a component of the strategy that is 
subject to the managed interest process pursuant to Rule 515(c) (as the 
System would reject a QCC Order in the simple market during such a 
condition).
---------------------------------------------------------------------------

    \29\ See supra note 18.
---------------------------------------------------------------------------

    Proposed Rule 515(h)(4)(A) states that cQCC Orders will be 
automatically cancelled if they cannot be executed. Proposed Rule 
515(h)(4)(B) provides that cQCC Orders may only be entered in the 
minimum trading increments applicable to complex orders under Rule 
518(c)(1)(i).\30\
---------------------------------------------------------------------------

    \30\ See supra note 20.
---------------------------------------------------------------------------

    Just as with cC2C Orders, proposed Rule 515(h)(4)(C)states that the 
Exchange will determine, on a class-by-class basis, the option classes 
in which cQCC Orders are available for trading on the Exchange, and 
will announce such classes to Members via Regulatory Circular.
    The following example illustrates the execution of a cQCC Order:
Example 2--A cQCC Order Is Executed
MIAX-LMM Mar 50 Call 6.00-6.50 (10x10--no Priority Customer interest)
MIAX-LMM Mar 55 Call 3.00-3.30 (10x10--no Priority Customer interest)
ABBO--Mar 50 Call 6.00-6.30 (10x10)
ABBO--Mar 55 Call 3.00-3.30 (10x10)
NBBO--Mar 50 Call 6.00-6.30 (20x10)
NBBO--Mar 55 Call 3.00-3.30 (20x20)

Strategy: Buy 1 Mar 50 Call, Sell 1 Mar 55 Call

The icMBBO is 2.70 debit bid at 3.50 credit offer
The dcMBBO is 2.70 debit bid at 3.50 credit offer
The ABBO is 2.70 debit bid at 3.30 credit offer

    The Exchange receives a cQCC Order representing Public Customers on 
both sides for the simultaneous purchase and sale of the strategy at a 
net price of 3.30, 1000 times along with information regarding the 
execution of the stock component relating to the crossing of 20,000 
shares of the underlying security (which information related to a 
separate

[[Page 25351]]

order that was sent to the stock execution venue by the Clearing Member 
previously identified to the Exchange as a Designated Give Up for the 
Member that submitted the cQCC Order in accordance with the Rule).
    Since the order can be executed at or between the NBBO for each leg 
of the Strategy, is not at the same price as a Priority Customer Order 
on the Exchange's Simple Order Book, and the order size and underlying 
security requirements have been met, the cQCC Order is automatically 
executed upon entry.
    The Exchange is proposing the same price execution requirements 
that are currently in place on other exchanges.\31\
---------------------------------------------------------------------------

    \31\ See, e.g., Securities Exchange Act Release No. 69948 (July 
9, 2013), 78 FR 42132 (July 15, 2013) (SR-CBOE-2013-41). See also, 
NYSEArca Regulatory Information Bulletin no. RBO-11-04 (May 26, 
2011).
---------------------------------------------------------------------------

Complex PRIME Orders
    As discussed above, the Exchange proposes to use the same PRIME 
mechanism for the processing and execution of cPRIME Orders that is 
used for PRIME Orders in the simple market. The manner in which cPRIME 
Orders will be processed and executed will be the same as the manner in 
which simple PRIME Orders are currently processed and executed, except 
as otherwise provided in proposed Interpretations and Policies .12 to 
Rule 515A. Accordingly, proposed Interpretations and Policies .12, 
PRIME for Complex Orders, states that, unless otherwise provided in 
Interpretations and Policies .12 to Rule 515A or unless the context 
otherwise requires, the provisions of Exchange Rule 515A(a) (which 
governs the processing and execution of simple PRIME orders) shall be 
applicable to the trading of complex orders on PRIME.
    Proposed Rule 518(b)(7) defines a cPRIME Order as a type of complex 
order that is submitted for participation in a cPRIME Auction. Trading 
of cPRIME Orders is governed by Rule 515A, Interpretations and Policies 
.12.
    The Exchange will determine, on a class-by-class basis, the option 
classes in which complex orders are available for trading on PRIME on 
the Exchange, and will announce such classes to Members via Regulatory 
Circular.
    The Exchange is proposing to amend Rule 515A(a)(2)(D) by stating 
clearly in the rule that the System will reject RFR responses submitted 
with a price that is not equal to or better than the initiating price. 
The purpose of this proposal is to avoid the handling of RFR responses 
by the System that could not be executed in an Auction because they are 
inferior to the initiating price, at which the Agency Order has been 
stopped. The Exchange is proposing to delete the last sentence of Rule 
515A(a)(2)(i)(D) which states simply that such RFR responses cannot 
cross the disseminated MBBO on the opposite side of the market from the 
response. Such a response would result in the conclusion of the Auction 
under current Rule 515A(2)(ii)(E), which states that the Auction will 
conclude any time an RFR response matches the NBBO on the opposite side 
of the market from the RFR responses. The Exchange is proposing to 
delete the last sentence of Rule 515A(a)(2)(i)(D), because the NBBO 
cannot be outside, or inferior to, the MBBO, and an RFR response 
therefore could not cross the MBBO without matching or crossing the 
NBBO, which stops the Auction. This provision in Rule 515A(a)(2)(i)(D) 
is unnecessary and should be deleted.
    Proposed Interpretations and Policies .12(a) to Rule 515A includes 
general rules applicable to cPRIME Orders and cPRIME Auctions. Under 
the proposal, Members may use PRIME to execute complex orders at a net 
price. In order to distinguish PRIME Auctions involving simple PRIME 
Orders from cPRIME Auctions involving cPRIME Orders, the Exchange is 
proposing to add new defined terms to Interpretations and Policies 
.12(a). Proposed Interpretations and Policies .12(a) states that 
``cPRIME'' is the process by which a Member may electronically submit a 
``cPRIME Order'' (as defined in proposed Rule 518(b)(7)) it represents 
as agent (a ``cPRIME Agency Order'') against principal or solicited 
interest for execution (a ``cPRIME Auction''). The Exchange is 
proposing to adopt these new terms for clarity and ease of reference.
    Proposed Interpretations and Policies .12(a)(i) to Rule 515A states 
that the initiating price for a cPRIME Agency Order must be better than 
(inside) the icMBBO \32\ for the strategy and any other complex orders 
on the Strategy Book. This ensures that the execution price of the 
cPRIME Agency Order improves the best price on the Exchange at the time 
of receipt, and that there is no interference between the simple and 
complex markets. The System will reject cPRIME Agency Orders submitted 
with an initiating price that is equal to or worse than (outside) the 
icMBBO or any other complex orders on the Strategy Book.
---------------------------------------------------------------------------

    \32\ See supra note 16.
---------------------------------------------------------------------------

    Proposed Interpretations and Policies .12(a)(ii) to Rule 515A 
states that Members may enter RFR responses on the opposite side of the 
market from the cPRIME Agency Order at net prices, and bids and offers 
for complex orders may participate in the execution of an order as 
provided in MIAX Options Rule 515A. The purpose of this provision is to 
clarify that cPRIME Auctions, including the RFR and RFR responses, 
will, with certain exceptions described herein, be handled and executed 
in the same manner as simple PRIME Auctions.
    Proposed Interpretations and Policies .12(a)(iii) to Rule 515A 
states that, except as provided in proposed Interpretations and 
Policies .12(c) (described below), with respect to bids and offers for 
the individual legs of a complex order entered into cPRIME, the order 
allocation rules contained in Rule 514 will apply. This ensures that 
simple orders on the Exchange's Simple Order Book are allocated under 
the simple order allocation rules when they are executed against the 
legs of a complex order.
    Proposed Interpretations and Policies .12(a)(iv) to Rule 515A 
states that, if an improved net price for the complex order being 
executed can be achieved from bids and offers for the individual legs 
of the complex order in the simple market, and the complex order is 
otherwise eligible for Legging pursuant to Rule 518(c)(2)(iii),\33\ the 
Strategy being matched will receive an execution at the better net 
price. The purpose of this provision is to ensure that the Exchange 
will provide the best net price available on the Exchange, whether by 
way of matching strategies or by way of Legging with the Simple Order 
Book, as long as the complex order is eligible for Legging.
---------------------------------------------------------------------------

    \33\ Complex orders up to a maximum number of legs (determined 
by the Exchange on a class-by-class basis as either two or three 
legs and communicated to Members via Regulatory Circular) may be 
automatically executed against bids and offers on the Simple Order 
Book for the individual legs of the complex order (``Legging''), 
provided the complex order can be executed in full or in a 
permissible ratio by such bids and offers, and provided that the 
execution price of each component is not executed at a price that is 
outside of the NBBO. Legging is not available for cAOC orders, 
complex Standard quotes, complex eQuotes, or stock-option orders. 
Notwithstanding the foregoing, complex orders with two option legs 
where both legs are buying or both legs are selling and both legs 
are calls or both legs are puts may only trade against other complex 
orders on the Strategy Book and will not be permitted to leg into 
the Simple Order Book. Complex orders with three option legs where 
all legs are buying or all legs are selling may only trade against 
other complex orders on the Strategy Book, regardless of whether the 
option leg is a call or a put. The System will not generate derived 
orders for these complex orders. See Exchange Rule 518(c)(2)(iii).
---------------------------------------------------------------------------

    Proposed Interpretations and Policies .12(a)(v) to Rule 515A states 
that all references to the NBBO in Rule 515A

[[Page 25352]]

are inapplicable.\34\ Any of the references to the NBBO in Rule 515A 
apply to simple orders and do not apply to complex orders; proposed 
Interpretations and Policies .12 replaces references to the NBBO with 
references to the icMBBO that apply to complex orders.
---------------------------------------------------------------------------

    \34\ Complex orders and quotes are executed without 
consideration of any prices for the complex strategy that might be 
available on other exchanges trading the same options contracts. See 
Exchange Rule 518(c)(2)(ii).
---------------------------------------------------------------------------

    The following example illustrates the execution of a cPRIME Order 
with the single price submission election (no auto-match):
Example 3--A cPRIME Order Is Executed (Without Auto-Match)
MIAX-LMM Mar 50 Call 6.00-6.50 (10x10)
MIAX-LMM Mar 55 Call 3.00-3.30 (10x10)

Strategy: Buy 1 Mar 50 Call, Sell 1 Mar 55 Call

The icMBBO is 2.70 debit bid at 3.50 credit offer
The dcMBBO is 2.70 debit bid at 3.50 credit offer

    The Strategy Book contains a Priority Customer offer to sell the 
Strategy at 3.30 credit, 20 times.
    The Exchange receives a cPRIME Order with the cPRIME Agency Order 
representing the purchase of the Strategy at a net debit of 3.29, 500 
times. Auto-match is not enabled.
    Since the order price is at least $0.01 better than (inside) the 
icMBBO and the best net price of any order for the Strategy on the 
Book, a cPRIME Auction can begin.
    An RFR is broadcast to all subscribers showing price, the quantity 
of matched complex orders at that price, and the side of the cPRIME 
Agency Order, is sent and a 500 millisecond RFR period is started.
    The following responses are received:

 @50 milliseconds BD1 response, cAOC Order @3.25 credit sell of 
100 arrives
 @150 milliseconds MM1 response, cAOC eQuote @3.27 credit sell 
of 100 arrives
 @200 milliseconds MM3 response, cAOC eQuote @3.29 credit sell 
of 200 arrives
 @300 milliseconds MM4 response, cAOC eQuote @3.29 credit sell 
of 200 arrives

    The cPRIME Auction process will continue until the Response Time 
Interval ends. When the 500 millisecond Response Time Interval ends, 
the cPRIME Auction process will trade the cPRIME Agency Order with the 
best priced responses. The cPRIME Agency order will be filled as 
follows:

 The cPRIME Agency Order buys 100 from BD1 @3.25
 The cPRIME Agency Order buys 100 from MM1 @3.27
 At the final price, the cPRIME Agency Order buys:

--50 from MM3 @3.29;
--50 from MM4 @3.29; and
--200 (40%) from the cPRIME Contra Order @3.29.

    The following example illustrates the execution of a cPRIME Order 
with the auto-match election:
Example 4--A cPRIME Order Is Executed (With Auto-Match)
MIAX-LMM Mar 50 Call 6.00-6.50 (10x10)
MIAX-LMM Mar 55 Call 3.00-3.30 (10x10)
Strategy: Buy 1 Mar 50 Call, Sell 1 Mar 55 Call

The icMBBO is 2.70 debit bid at 3.50 credit offer
The dcMBBO is 2.70 debit bid at 3.50 credit offer

    The Strategy Book contains a Priority Customer offer to sell the 
Strategy at 3.30 credit, 20 times.
    The Exchange receives a cPRIME Order with the cPRIME Agency Order 
representing the purchase of the Strategy at a net debit of 3.29, 500 
times. Auto-match has been enabled with an auto-match limit price of 
3.25.
    Since the order price is at least $0.01 better than (inside) the 
icMBBO and the best net price of any order for the Strategy on the 
Book, a cPRIME Auction can begin.
    An RFR is broadcast to all subscribers showing price, the quantity 
of matched complex orders at that price, and the side of the cPRIME 
Agency Order, is sent and a 500 millisecond RFR period is started.
    The following responses are received:

 @50 milliseconds BD1 response, cAOC Order @3.25 credit sell of 
100 arrives
 @150 milliseconds MM1 response, cAOC eQuote @3.27 credit sell 
of 300 arrives

    The cPRIME Auction process will continue until the Response Time 
Interval ends. When the 500 millisecond Response Time Interval ends, 
the cPRIME Auction process will trade the Agency Order with the best 
priced responses. The Agency Order will be filled as follows:

 At the interim price, the cPRIME Agency Order buys:

--100 from BD1 @3.25; and
--100 (auto-match RFR Response) from the cPRIME Contra Order @3.25.

 At the final price, the cPRIME Agency Order buys:

--150 from MM1 @3.27; and
--150 (auto-match 50% of the remaining Agency Order size) from the 
cPRIME Contra Order @3.27

    The following example illustrates the execution of a cPRIME Order 
that legs into the simple market:
Example 5--A cPRIME Order Is Executed (by Legging Into the Simple 
Market)
MIAX-LMM Mar 50 Call 6.00-6.50 (10x10)
MIAX-LMM Mar 55 Call 3.00-3.30 (10x10)

Strategy: Buy 1 Mar 50 Call, Sell 1 Mar 55 Call

The icMBBO is 2.70 debit bid at 3.50 credit offer
The dcMBBO is 2.70 debit bid at 3.50 credit offer

    The Strategy Book contains a Priority Customer offer to sell the 
Strategy at 3.30 credit, 20 times.
    The Exchange receives a cPRIME Order with the cPRIME Agency Order 
representing the purchase of the Strategy at a net debit of 3.29, 500 
times. Auto-match is not enabled.
    Since the order price is at least $0.01 better than (inside) the 
icMBBO and the best net price of any order for the Strategy on the 
Book, a cPRIME Auction can begin.
    An RFR is broadcast to all subscribers showing price, the quantity 
of matched complex orders at that price, and the side of the cPRIME 
Agency Order, is sent and a 500 millisecond RFR period is started.
    The following responses are received:

 @150 milliseconds MM2 response, cAOC Order @3.28 credit sell 
of 100 arrives
 @200 milliseconds MM1 response, cAOC Order @3.27 credit sell 
of 300 arrives
 @300 milliseconds the MIAX LMM improves its offer to sell 10 
Mar 50 Calls to a price of 6.25

    The offer to sell 10 Mar 50 Calls @6.25 changes the icMBBO credit 
offer to 3.25, crossing the Auction Start Price and causing the cPRIME 
Auction process to be terminated immediately.
    The cPRIME Auction process will trade the Agency Order with the 
best priced liquidity opposite the Agency Order according to the 
allocation process contained in Rule 515A. The Agency Order will be 
filled as follows:

 The cPRIME Agency Order buys:

--10 from legging into the Simple market icMBBO @3.25 (buy 10 Mar 50 
Calls at 6.25, and sell 10 Mar 55 Calls at 3.00); and

[[Page 25353]]

--300 from MM1 @3.27; and
--100 from MM2 @3.28; and
--90 from the cPRIME Contra Order @3.29

    There are certain circumstances that are unique to cPRIME Orders 
(such as when a component of the cPRIME Order is in a certain state), 
where the System will reject the cPRIME Order. Accordingly, proposed 
Interpretations and Policies .12(b) describes each of these specific 
circumstances. Specifically, the System will reject a cPRIME Agency 
Order if, at the time of receipt of the cPRIME Agency Order: (i) The 
strategy is subject to a cPRIME Auction or to a Complex Auction 
pursuant to Rule 518(d); (ii) any component of the strategy is subject 
to a SMAT Event as described in Rule 518(a)(16); or (iii) any component 
of the strategy is subject to the managed interest process described in 
Rule 515(c)(1)(ii). The purpose of this provision is to maintain an 
orderly market by avoiding simultaneous multiple cPRIME Auctions and 
multiple concurrent PRIME, cPRIME and Complex Auctions, and to avoid 
executions during a Route Timer \35\ or liquidity refresh pause \36\ 
that could affect the price of the components and of the strategy.
---------------------------------------------------------------------------

    \35\ For those initiating Public Customer orders that are 
routable, but do not meet the additional criteria for Immediate 
Routing, the System will implement a Route Timer not to exceed one 
second (the duration of the Timer will be announced to Members 
through a Regulatory Circular), in order to allow Market Makers and 
other participants an opportunity to interact with the initiating 
order. See Exchange Rule 529(b)(2)(i).
    \36\ The System will pause the market for a time period not to 
exceed one second to allow additional orders or quotes refreshing 
the liquidity at the MBBO to be received (``liquidity refresh 
pause'') when at the time of receipt or reevaluation of the 
initiating order by the System: (A) Either the initiating order is a 
limit order whose limit price crosses the NBBO or the initiating 
order is a market order, and the limit order or market order could 
only be partially executed; (B) a Market Maker quote was all or part 
of the MBBO when the MBBO is alone at the NBBO; and (C) and the 
Market Maker quote was exhausted. See Exchange Rule 515(c)(2).
---------------------------------------------------------------------------

    The Exchange believes that, if the System were to accept and 
process cPRIME Agency Orders during the various circumstances described 
in proposed Interpretations and Policies .12(b) to Rule 515A, market 
participants could be faced with a number of simultaneous PRIME, cPRIME 
and/or Complex Auctions involving the same strategy or component, which 
in turn could have an impact the orderly functioning of the markets.
    Proposed Interpretations and Policies .12(c) to Rule 515A describes 
various other situations that are unique to, or otherwise apply 
specifically to, cPRIME Orders. The purpose of this provision is to 
``carve out'' rules for cPRIME Orders for which the rules for simple 
PRIME Orders do not apply and to otherwise make clear in the Exchange's 
rules the manner in which cPRIME Orders will be processed and executed 
under the proposal. Accordingly, proposed Interpretations and Policies 
.12(c) states that, notwithstanding the provisions of this Rule 515A 
with respect to PRIME, the following shall apply to cPRIME Orders only.
    Proposed Interpretations and Policies .12(c)(i) to Rule 515A states 
that the RFR period for cPRIME Auctions shall be independent from the 
RFR for PRIME Auctions and shall last for a period of time set forth in 
Rule 515A(a)(2)(i)(C). The current RFR period for PRIME Auctions is 500 
milliseconds.\37\
---------------------------------------------------------------------------

    \37\ The Exchange notes that, on April 13, 2017, it filed with 
the Commission a proposed rule change (SR-MIAX-2017-16) that would 
amend the duration of the RFR period contained in Rule 
515A(a)(2)(i)(c) so that the duration can be a period of time within 
a range of no less than 100 milliseconds and no more than 1 second, 
as determined by the Exchange and announced via Regulatory Circular. 
If approved, such provision would allow a separate and potentially 
different time period for simple PRIME Auctions and cPRIME Auctions, 
provided that each time period is within the permissible range. The 
Exchange notes that MIAX's proposed rule change to amend the 
duration of a PRIME Auction was published in the Federal Register on 
May 5, 2017 and is subject to a public comment period expiring on 
May 26, 2017. See Securities Exchange Act Release No. 80570 (May 1, 
2017), 82 FR 21288 (May 5, 2017) (SR-MIAX-2017-16) Notice of Filing 
of a Proposed Rule Change to Amend MIAX Options Rule 515A, MIAX 
Price Improvement Mechanism (``PRIME'') and PRIME Solicitation 
Mechanism.
---------------------------------------------------------------------------

    The Exchange is proposing to adopt Interpretations and Policies 
.12(c)(ii) to Rule 515A which states that participants that submit 
simple orders that are executed as individual legs of complex orders at 
the execution price point will be allocated contracts only after all 
complex interest at such price point have received allocations. cPRIME 
Orders are matched first against other complex orders and have priority 
over simple orders that are on the Book and ``legged,'' at the 
execution price, regardless of the origin code of the simple order. The 
Exchange believes that this is appropriate because the initiating price 
of the cPRIME Agency Order is always superior to the net price of 
simple orders resting on the Simple Order Book. The Agency Order is 
submitted at an improved price with an accompanying contra side order 
(principal or solicited interest) that is intended to trade with all 
components of the Agency Order at a net price at the time of 
submission. Simple orders resting on the Book do not necessarily intend 
to trade with the legs of the Agency Order, and thus the Exchange 
believes that it is equitable and not unfairly discriminatory to afford 
priority to complex interest over simple interest.
    Additionally, under the proposal, when new interest is received in 
the simple market that causes the icMBBO on the opposite side of the 
market from the cPRIME Agency Order to be equal to or better than the 
initiating price, the cPRIME Auction ends before the expiration of the 
RFR period. In this situation, the receipt of such an order simply ends 
the cPRIME Auction and the execution and allocation process is 
accelerated, prior to the end of the RFR period.
    Regardless of when the cPRIME Auction ends, contracts are first 
allocated by matching complex strategies; thereafter, contracts that 
are executed by way of Legging \38\ complex strategy components against 
the Book are allocated among the complex strategies, and then finally 
among the simple orders on the Book that are matched with components of 
the Legged strategy. Thus, the allocation process is not changed, and 
simple orders resting on the book that may be executed by way of 
Legging are still subject to complex order priority interest and are 
allocated contracts only after all complex interest has been filled at 
that price. The Exchange believes that it is consistent, equitable and 
not unfairly discriminatory to afford priority to complex interest over 
simple interest even when Complex Auction ends early.\39\
---------------------------------------------------------------------------

    \38\ See Exchange Rule 518(c)(2)(iii).
    \39\ The Exchange notes that other exchanges afford priority to 
complex interest over simple interest. See, e.g., NASDAQ PHLX, LLC 
(``PHLX'') Rule 1098(e)(vi)(A)(2); see also, PHLX Rule 
1098(e)(viii)(C)(3).
---------------------------------------------------------------------------

    The Exchange believes that its proposal to afford priority to 
complex orders in cPRIME over simple orders is appropriate because it 
rewards participants that assume greater market risk and actively 
improves the execution price by submitting complex RFR responses in a 
cPRIME Auction. A simple order on the Book is not responding to an RFR 
for price improvement, and thus the Exchange believes that it is 
equitable and not unfairly discriminatory to afford priority to complex 
orders in a cPRIME Auction over simple orders on the MIAX Options Book. 
The Exchange believes that affording priority to complex interest over 
simple interest on the Simple Order Book is consistent with Section 
6(b) of the Act \40\ in general, and furthers the objectives of Section 
6(b)(5)

[[Page 25354]]

of the Act \41\ in particular, in that it promotes just and equitable 
principles of trade by affording priority to participants submitting 
cPRIME Orders and RFR responses that are intended to improve the then-
existing price on the Exchange. The Exchange believes that affording 
this priority encourages participants to submit more price-improving 
complex orders, and that they should be rewarded with priority over 
simple orders that are resting on the Simple Order Book that were not 
submitted or intended to be price improving orders.

    The following example illustrates the execution and allocation of a 
cPRIME Order (with simple interest allocated after all complex interest 
has been allocated):
Example 6--A cPRIME Order Is Executed (Simple Interest Allocated After 
Complex Interest)
MIAX-LMM Mar 50 Call 6.00-6.50 (10x10)
MIAX-LMM Mar 55 Call 3.00-3.30 (10x10)

Strategy: Buy 1 Mar 50 Call, Sell 1 Mar 55 Call

The icMBBO is 2.70 debit bid at 3.50 credit offer
The dcMBBO is 2.70 debit bid at 3.50 credit offer

    The Strategy Book contains a Priority Customer offer to sell the 
Strategy at 3.30 credit, 20 times.
    The Exchange receives a cPRIME Order with the cPRIME Agency Order 
representing the purchase of the Strategy at a net debit of 3.29, 500 
times. Auto-match is not enabled.
    Since the order price is at least $0.01 better than (inside) the 
icMBBO and the best net price of any order for the Strategy on the 
Book, a cPRIME Auction can begin.
    An RFR is broadcast to all subscribers showing price, the quantity 
of matched complex orders at that price, and the side of the cPRIME 
Agency Order, is sent and a 500 millisecond RFR period is started.
    The following responses are received:

 @250 milliseconds MM2 response, cAOC Order @3.25 credit sell 
of 500 arrives
 @300 milliseconds the MIAX LMM improves its offer to sell 10 
Mar 50 Calls to a price of 6.25

    The offer to sell 10 Mar 50 Calls @6.25 changes the icMBBO credit 
offer to 3.25, crossing the Auction Start Price and causing the cPRIME 
Auction process to be terminated immediately.
    The cPRIME Auction process will trade the Agency Order with the 
best priced liquidity opposite the Agency Order according to the 
allocation process contained in Rule 515A. The Agency Order will be 
filled as follows:

 The cPRIME Agency Order buys:

--500 from MM2 @3.25
--Simple Interest receives no allocation

    Proposed Interpretations and Policies .12(c)(iii) to Rule 515A 
states that the size and bid/ask differential provisions contained in 
Exchange Rule 515A(a)(1)(iii) \42\ shall not apply to cPRIME Orders. 
Rule 515A(a)(1) is intended to apply to simple PRIME Auctions, and not 
to apply to complex orders.\43\ Under Rule 515A(a)(1)(iii), with 
respect to Agency Orders that have a size of less than 50 contracts, if 
at the time of receipt of the Agency Order, the NBBO has a bid/ask 
differential of $0.01, the System will reject the Agency Order. This 
rule would not apply to complex orders, including cPRIME Orders, 
because the NBBO is not a consideration in determining the execution 
price of a complex order.\44\
---------------------------------------------------------------------------

    \42\ With respect to Agency Orders that have a size of less than 
50 contracts, if at the time of receipt of the Agency Order, the 
NBBO has a bid/ask differential of $0.01, the System will reject the 
Agency Order. See Exchange Rule 515A(a)(1)(iii).
    \43\ In late 2016, the Exchange filed to adopt new Rule 
515A(a)(1)(iii), upon the expiration of a Pilot, to establish on a 
permanent basis that, with respect to Agency Orders that have a size 
of less than 50 contracts, if at the time of receipt of the Agency 
Order, the NBBO has a bid/ask differential of $0.01, the System will 
reject the Agency Order. Agency Orders with a size of under 50 
contracts will be accepted and processed by the System when the NBBO 
bid/ask differential is greater than $0.01, and all Agency Orders 
with a size of 50 contracts or greater will be accepted and 
processed by the System, regardless of the NBBO bid/ask 
differential. The Pilot and Rule 515A(a)(1)(iii) do not apply to 
Complex Orders. See Securities Exchange Act Release No. 79837 
(January 18, 2017), 82 FR 8472 (January 25, 2017) (SR-MIAX-2016-46).
    \44\ See proposed Exchange Rule 515A, Interpretations and 
Policies .12(a)(v).
---------------------------------------------------------------------------

    Proposed Interpretations and Policies .12(c)(iv) to Rule 515A 
states that the conclusion of auction provisions contained in Rule 
515A(a)(2)(ii) shall not apply to cPRIME Auctions. Rather, the Exchange 
is proposing to adopt a separate set of provisions relating to the 
conclusion of auctions that apply only to cPRIME Auctions, in proposed 
Interpretations and Policies .12(d), discussed below.
    Proposed Rule 515A, Interpretations and Policies .12(c)(v), states 
that the order allocation provisions contained in Rule 515A(a)(2)(iii) 
shall apply to cPRIME Auctions, provided that (A) all references to 
contracts shall be deemed to be references to complex strategies; \45\ 
and (B) the last priority allocation option described in Rule 
515A(a)(2)(iii)(L) is not available for Initiating Members that submit 
cPRIME Agency Orders. With respect to cPRIME Auctions, the System 
allocates complex strategies, not contracts. Additionally, the last 
priority allocation option described in Rule 515A(a)(iii)(L) \46\ is 
not available for Initiating Members that submit cPRIME Agency Orders. 
The Exchange believes that there is not significant Member demand for 
the use of the last priority allocation option in cPRIME Auctions, 
which obviates the need for its inclusion in the allocation model for 
cPRIME Auctions.
---------------------------------------------------------------------------

    \45\ The term ``complex strategy'' means a particular 
combination of components and their ratios to one another. New 
complex strategies can be created as the result of the receipt of a 
complex order or by the Exchange for a complex strategy that is not 
currently in the System. The Exchange may limit the number of new 
complex strategies that may be in the System at a particular time 
and will communicate this limitation to Members via Regulatory 
Circular. See Exchange Rule 518(a)(6).
    \46\ If the Initiating Member elected to have last priority in 
allocation when submitting an Agency Order to initiate an Auction 
against a single-price submission, the Initiating Member will be 
allocated only the amount of contracts remaining, if any, after the 
Agency Order is allocated to all other responses at the single price 
specified by the Initiating Member. See Exchange Rule 
515A(a)(iii)(L).
---------------------------------------------------------------------------

    Finally, proposed Interpretations and Policies .12(c)(vi), which 
states that provisions contained in Interpretations and Policies .06 
and .07 of Rule 515A shall not apply to cPRIME Auctions. 
Interpretations and Policies .06 and .07 relate to the managed interest 
process and route timers on the same and opposite sides of the Agency 
Order in PRIME Auctions. Proposed Interpretations and Policies .12(b) 
specifically states that cPRIME Agency Orders will be rejected if 
received during these conditions. Therefore, Interpretations and 
Policies .06 and .07 will not apply to cPRIME Auctions.
Conclusion of the cPRIME Auction
    Proposed Interpretations and Policies .12(d) to Rule 515A describes 
the circumstances under which a cPRIME Auction is concluded. Proposed 
Interpretations and Policies .12(d)(i) to Rule 515A states that the 
cPRIME Auction shall conclude at the sooner to occur of the following 
events (described below) with the cPRIME Agency Order executing 
pursuant to proposed Rule 515A(2)(iii).
    First, a cPRIME Auction will conclude at the end of the RFR period. 
This completes the cPRIME Auction.
    A cPRIME Auction will conclude when an AOC eQuote \47\ or cAOC

[[Page 25355]]

Order \48\ (the permitted RFR responses \49\) on the opposite side of 
the market from the cPRIME Agency Order locks or crosses: (A) The 
icMBBO, or (B) the best net price of a complex order in the same 
strategy on the Strategy Book, whichever is more aggressive.
---------------------------------------------------------------------------

    \47\ A ``Complex Auction or Cancel eQuote'' or ``cAOC eQuote,'' 
is an eQuote submitted by a Market Maker that is used to provide 
liquidity during a specific Complex Auction with a time in force 
that corresponds with the duration of the Complex Auction. See 
Exchange Rule 518, Interpretations and Policies .02(c)(1).
    \48\ A Complex Auction-or-Cancel or ``cAOC'' order is a complex 
limit order used to provide liquidity during a specific Complex 
Auction with a time in force that corresponds with that event. See 
Exchange Rule 518(b)(3).
    \49\ Members may submit responses to the RFR (specifying prices 
and sizes). RFR responses shall be an Auction or Cancel (``AOC'') 
order or an AOC eQuote. See Exchange Rule 515A(a)(2)(i)(D). This 
applies by reference to cPRIME Auctions (and cAOC eQuotes and cAOC 
orders). See proposed Interpretations and Policies .12(a).
---------------------------------------------------------------------------

    Pursuant to proposed Interpretations and Policies .12(d)(iii) to 
Rule 515A, a cPRIME Auction will conclude when unrelated interest on 
the same side of the market as the cPRIME Agency Order locks or crosses 
the best price on the opposite side of the market.
    Proposed Interpretations and Policies .12(d)(iv) to Rule 515A 
states that a cPRIME Auction will conclude when unrelated interest on 
the opposite side of the market from the cPRIME Agency Order (A) locks 
or crosses (1) the icMBBO, or (2) the best net price of a complex order 
in the same strategy on the Strategy Book, whichever is more aggressive 
(e.g., a higher bid or lower offer); or (B) improves the price of any 
RFR response.
    Under proposed Interpretations and Policies .12(d)(v) to Rule 515A, 
a cPRIME Auction will conclude when a simple order or quote in a 
component of the strategy on the same side of the market as the cPRIME 
Agency Order locks or crosses the NBBO for such component. Proposed 
Interpretations and Policies .12(d)(vi) states that a cPRIME Auction 
will conclude when a simple order or quote in a component of the 
strategy on the opposite side of the market from the cPRIME Agency 
Order (A) locks or crosses the NBBO for such component, or (B) causes 
the icMBBO to be equal to or better than the initiating price. These 
provisions ensure that a cPRIME Agency Order will always receive the 
best price on the Exchange, while at the same time preserving the 
sanctity of the simple market.
Allocation of Contracts at the Conclusion of the cPRIME Auction
    Except as provided in proposed Interpretations and Policies .12(c) 
to Rule 515A, at the conclusion of the Auction, the cPRIME Order will 
be allocated in the same manner as simple PRIME Orders in the simple 
PRIME Auction at the best price(s) as set forth in Rule 515A. Proposed 
Interpretations and Policies .12(c)(v) states that the order allocation 
provisions contained in Rule 515A(a)(2)(iii) shall apply to cPRIME 
Auctions, provided that, as described above: All references to 
contracts shall be deemed to be references to complex strategies as 
defined in Rule 518(a)(6); and the last priority allocation option 
described in Rule 515A(a)(2)(iii)(L) is not available for Initiating 
Members that submit cPRIME Agency Orders.
    Exchange Rule 515A(a)(2)(iii) currently provides that at the 
conclusion of the PRIME Auction, the Agency Order will be allocated at 
the best price(s), subject to the following: (A) Such best prices 
include non-Auction quotes and orders; (B) Priority Customer \50\ 
orders resting on the Book before, or that are received during, the 
Response Time Interval and Priority Customer RFR responses shall, 
collectively have first priority to trade against the Agency Order. The 
allocation of an Agency Order against the Priority Customer orders 
resting in the Book, Priority Customer orders received during the 
Response Time Interval, and Priority Customer RFR responses shall be in 
the sequence in which they are received by the System; (C) Market Maker 
priority quotes and RFR responses from Market Makers \51\ with priority 
quotes will collectively have second priority. The allocation of Agency 
Orders against these contra sided quotes and RFR responses shall be on 
a size pro rata basis as defined in Rule 514(c)(2); (D) Professional 
Interest orders resting in the Book, Professional Interest orders 
placed in the Book during the Response Time Interval, Professional 
Interest quotes, and Professional Interest RFR responses will 
collectively have third priority. The allocation of Agency Orders 
against these contra sided orders and RFR Responses shall be on a size 
pro rata basis as defined in Rule 514(c)(2); (E) No participation 
entitlement shall apply to orders executed pursuant to this Rule; (F) 
If an unrelated market or marketable limit order on the opposite side 
of the market as the Agency Order was received during the Auction and 
ended the Auction, such unrelated order shall trade against the Agency 
Order at the midpoint of the best RFR response (or in the absence of a 
RFR response, the initiating price) and the NBBO on the other side of 
the market from the RFR responses (rounded towards the disseminated 
quote when necessary). (G) If an unrelated non-marketable limit order 
on the opposite side of the market as the Agency Order was received 
during the Auction and ended the Auction, such unrelated order shall 
trade against the Agency Order at the midpoint of the best RFR response 
and the unrelated order's limit price (rounded towards the unrelated 
order's limit price when necessary).
---------------------------------------------------------------------------

    \50\ See supra note 6.
    \51\ The term ``Market Makers'' refers to ``Lead Market 
Makers,'' ``Primary Lead Market Makers,'' and ``Registered Market 
Makers,'' collectively. The term ``Lead Market Maker'' means a 
Member registered with the Exchange for the purpose of making 
markets in securities traded on the Exchange and that is vested with 
the rights and responsibilities specified in Chapter VI of the 
Exchange's Rules with respect to Lead Market Makers. When a Lead 
Market Maker is appointed to act in the capacity of a Primary Lead 
Market Maker, the additional rights and responsibilities of a 
Primary Lead Market Maker specified in Chapter VI of the Exchange's 
Rules will apply. The term ``Primary Lead Market Maker'' means a 
Lead Market Maker appointed by the Exchange to act as the Primary 
Lead Market Maker for the purpose of making markets in securities 
traded on the Exchange. The Primary Lead Market Maker is vested with 
the rights and responsibilities specified in Chapter VI of the 
Exchange's Rules with respect to Primary Lead Market Makers. The 
term ``Registered Market Maker'' means a Member registered with the 
Exchange for the purpose of making markets in securities traded on 
the Exchange, who is not a Lead Market Maker and is vested with the 
rights and responsibilities specified in Chapter VI of the 
Exchange's Rules with respect to Registered Market Makers. See 
Exchange Rule 100.
---------------------------------------------------------------------------

    Rules 515A(a)(2)(iii)(H) and (I) describe the allocation of 
contracts executed when the Initiating Member selects the single-price 
submission or the auto-match option, respectively, when submitting 
their Agency Order and there are either two or more participants at the 
execution price or when there is only one other participant on parity 
with the Initiating Member at either the single price execution price 
or at the final auto-match price point.
    Exchange Rules 515A(a)(2)(iii)(H) and (I) currently state that, 
upon conclusion of an Auction, an Initiating Member will retain certain 
priority and trade allocation privileges for a single-price submission 
and for an auto-match submission. Under current Rule 
515A(a)(2)(iii)(H), if the best price equals the Initiating Member's 
single-price submission, the Initiating Member's single-price 
submission shall be allocated the greater of one contract or a certain 
percentage of the order, which percentage will be determined by the 
Exchange and may not be larger than 40% of the Agency Order. However, 
if only one Member's response matches the Initiating Member's single 
price submission, then the Initiating Member may be allocated up to 50% 
of the Agency Order.
    Similarly, current Exchange Rule 515A(a)(2)(iii)(I) provides that 
if the Initiating Member selected the auto-match option of the Auction, 
the Initiating Member shall be allocated its

[[Page 25356]]

full size of RFR responses at each price point until the final auto-
match price point is reached. At the final auto-match price point, the 
Initiating Member shall be allocated the greater of one contract \52\ 
or a certain percentage of the remainder of the Agency Order, which 
percentage will be determined by the Exchange and may not be larger 
than 40%. However, if only one Member's response matches the Initiating 
Member's submission at the final auto-match price point, then the 
Initiating Member may be allocated up to 50% of the remainder of the 
Agency Order at the final auto-match price point.
---------------------------------------------------------------------------

    \52\ Under the proposal, with respect to order allocation, all 
references to contracts shall be deemed to be references to complex 
strategies. See Proposed Rule 515A, Interpretations and Policies 
.12(c)(v)(A).
---------------------------------------------------------------------------

    At the conclusion of the Auction, the Agency Order is allocated at 
the best price(s) pursuant to the matching algorithm in effect for the 
class.\53\ The System first must determine the number of participants 
that are entitled to receive contracts to be allocated, and whether any 
participant(s) such as Priority Customers are entitled to receive 
contracts first. Thereafter, contracts are allocated among participants 
at the execution price.
---------------------------------------------------------------------------

    \53\ See Exchange Rule 515A(a)(2)(iii).
---------------------------------------------------------------------------

    Finally, the Exchange is proposing to amend Rule 518(c) to clarify 
that the processing and execution of these three new complex order 
types is governed by Exchange Rule 515 (for cC2C Orders and cQCC 
Orders) and Exchange Rule 515A (for cPRIME Orders), as specified in the 
definition of each new complex order type under 518(b).
    As a technical numbering matter, the Exchange is proposing to mark 
Interpretations and Policies .10 and .11 to Rule 515A ``Reserved'' 
because these two numbers are being used in a separate proposed rule 
change which has not been published as of the filing date of the 
instant proposed rule change.
    The Exchange will announce the implementation date of the proposed 
rule change by Regulatory Circular to be published no later than 60 
days following the operative date of the proposed rule. The 
implementation date will be no later than 60 days following the 
issuance of the Regulatory Circular.
2. Statutory Basis
    MIAX believes that its proposed rule change is consistent with 
Section 6(b) of the Act \54\ in general, and furthers the objectives of 
Section 6(b)(5) of the Act \55\ in particular, in that it is designed 
to prevent fraudulent and manipulative acts and practices, to promote 
just and equitable principles of trade, to foster cooperation and 
coordination with persons engaged in regulating, clearing, settling, 
processing information with respect to, and facilitating transactions 
in securities, to remove impediments to and perfect the mechanisms of a 
free and open market and a national market system and, in general, to 
protect investors and the public interest.
---------------------------------------------------------------------------

    \54\ 15 U.S.C. 78f(b).
    \55\ 15 U.S.C. 78f(b)(5).
---------------------------------------------------------------------------

    The proposal to amend Exchange Rules 515, 515A, and 518 to 
establish three new complex order types, and to adopt new provisions 
that relate to the processing of those new complex order types is 
consistent with Section 6(b)(5) of the Act because this proposal 
promotes just and equitable principles of trade and protects investors 
and the public interest by providing increased opportunities for the 
execution of complex orders. The Exchange believes that the new cC2C, 
cQCC, and cPRIME order types will benefit MIAX Options participants and 
the marketplace as a whole by providing more ways in which complex 
orders are able to interact with one another, and in some instances 
through Legging with the simple market. The Exchange believes the 
proposed rule change removes impediments to and perfects the mechanism 
of a free and open market and a national market system and will result 
in more efficient trading and enhance the likelihood that complex 
orders execute at the best prices by providing additional order types 
resulting in potentially greater liquidity available for trading on the 
Exchange.
    The proposed rule change will make existing functionality available 
to additional order types. Making PRIME available for complex orders 
removes impediments to and perfects the mechanisms of a free and open 
market and a national market system because Members will be given 
additional ways in which they can seek liquidity for complex orders 
with the potential for price improvement on the Exchange.
    The proposed rule change will protect investors and the public 
interest by assuring that the existing priority and allocation rules 
applicable to the processing and execution of Customer Cross Orders, 
QCC Orders, and PRIME Orders remains consistent with the processing and 
execution of these new order types, unless as otherwise specifically 
set forth in the rules.
    The Exchange believes that the requirement that the execution of 
cC2C be at least $0.01 better than (inside) either the icMBBO price or 
the best net price of a complex order on the Strategy Book, whichever 
is more aggressive, protects investors and the public interest by 
ensuring that each side of the cC2C Order receives a better price than 
it would receive if submitted as a single complex order. MIAX Options 
participants will thus receive the best prices available for both sides 
of a cC2COrder.
    The Exchange further believes that the proposed methodology for the 
execution of cQCC Orders without consideration of the NBBO of the stock 
component is consistent with the Plan. As stated above, the Plan 
provides an exception to the requirement that Participants establish, 
maintain and enforce written policies and procedures that are 
reasonably designed to prevent Trade-Throughs when the transaction that 
constituted the Trade-Through was effected as a portion of a ``complex 
trade,'' as defined in the rules of a Participant.\56\ Therefore, the 
System considers the NBBO for each option leg of the cQCC Order, and 
not the NBBO for the stock component, in calculating the pricing 
requirement for cQCC Orders.
---------------------------------------------------------------------------

    \56\ See supra note 25.
---------------------------------------------------------------------------

    The System does not consider the NBBO price for the stock component 
because the Exchange does not execute the stock component; the Exchange 
executes the option components at a net price and ensures that the 
execution price of each option component of the strategy is (i) not at 
the same price as a Priority Customer Order on the Exchange's Book; and 
(ii) at or between the NBBO. The Exchange does require that the Member 
entering the cQCC Order provide certain information to the Exchange 
regarding the execution of the stock component, such as the underlying 
price, quantity, price delta, execution time and executing venue.\57\
---------------------------------------------------------------------------

    \57\ See supra note 27.
---------------------------------------------------------------------------

    This complex pricing requirement aligns with the simple order 
pricing requirement for a Qualified Contingent Trade (``QCT'') to 
consider the NBBO price. In each case, the parties to a contingent 
trade are focused on the spread or ratio between the transaction prices 
for each of the component instruments (i.e., the net price of the 
entire contingent trade), rather than on the absolute price of any 
single component. Pursuant to the requirements of the NMS QCT 
Exemption, the spread or ratio between the relevant instruments must be 
determined at the time the order is placed, and this spread or ratio 
stands regardless of the market prices of the individual orders at 
their time of execution. As the Commission noted in the Original QCT 
Exemption, ``the

[[Page 25357]]

difficulty of maintaining a hedge, and the risk of falling out of 
hedge, could dissuade participants from engaging in contingent trades, 
or at least raise the cost of such trades.'' Thus, the Commission found 
that, if each stock leg of a qualified contingent trade were required 
to meet the trade-through provisions of Rule 611 of Regulation NMS, 
such trades could become too risky and costly to be employed 
successfully and noted that the elimination or reduction of this 
trading strategy potentially could remove liquidity from the 
market.\58\ This is also true for QCC Orders in options, and thus the 
Exchange believes that its proposal is consistent with the Original QCT 
Exemption.\59\
---------------------------------------------------------------------------

    \58\ See supra note 28.
    \59\ Id.
---------------------------------------------------------------------------

    The Exchange believes that the proposal to reject a cC2C or cQCC 
Order at the time of receipt of the Order when any component of the 
strategy is subject to a PRIME Auction, Complex Auction, or a SMAT 
Event removes impediments to and perfects the mechanisms of a free and 
open market and a national market system by avoiding concurrent order 
processing in the same security on the Exchange.
    The Exchange believes that the rejection of cC2C Orders and cQCC 
Orders when the strategy is subject to a cPRIME or Complex Auction 
removes impediments to and perfects the mechanisms of a free and open 
market by ensuring orderly markets involving multiple complex orders 
with common components.
    Similarly, the proposed rejection of cPRIME Agency Orders when the 
strategy is subject to a cPRIME Auction or a Complex Auction, or any 
component of the strategy is subject to a SMAT Event or the managed 
interest process, protects investors and the public interest by 
ensuring that the strategy and its components are handled by the System 
in an orderly fashion without multiple simultaneous cPRIME Auctions, 
SMAT Events or the managed interest processes.
    The Exchange also believes that the pricing requirements under 
which the initiating price for a cPRIME Agency Order must be better 
than (inside) the icMBBO for the strategy and any other complex orders 
on the Strategy Book perfects the mechanisms of a free and open market 
and a national market system and, in general, protects investors and 
the public interest, by ensuring that the initiating price results in 
executions in cPRIME Auctions at an improved price or prices.
    The proposal to establish rules setting forth the various 
circumstances under which the system will conclude cPRIME Auction is 
designed to facilitate transactions, to remove impediments to and 
perfect the mechanism of a free and open market by freeing up interest 
in the cPRIME Auction when unrelated orders or other conditions cause 
the initiating price of the cPRIME Order to no longer be at the best 
price available to market participants.
    The Exchange believes that its proposal to afford priority to 
complex orders in cPRIME over simple orders is appropriate because it 
rewards participants that assume greater market risk and actively 
improve the execution price by submitting complex RFR responses in a 
cPRIME Auction. A simple order on the Book is not responding to an RFR 
for price improvement, and thus the Exchange believes that it is 
equitable and not unfairly discriminatory to afford priority to complex 
orders in a cPRIME Auction over simple orders on the Simple Order Book. 
The Exchange believes that affording priority to complex interest over 
simple interest on the Simple Order Book promotes just and equitable 
principles of trade by affording priority to participants submitting 
cPRIME Orders and RFR responses that are intended to improve the 
execution price on the Exchange. The Exchange believes that affording 
this priority encourages participants to submit more price-improving 
complex orders, and that they should be rewarded with priority over 
simple orders that are resting on the Simple Order Book that were not 
submitted or intended to be price improving orders.
    Additionally, when the cPRIME Auction ends prior to the expiration 
of the RFR period due to the receipt of new interest that causes the 
icMBBO to be equal to or better than the initiating price, the Exchange 
believes that it is equitable and not unfairly discriminatory to 
continue to afford priority at each price point to complex interest 
over simple interest resting on the Simple Order Book that is executed 
against the individual legs of a complex order. In this situation, the 
new interest is arriving after complex orders at the same price; the 
receipt of such an order simply ends the cPRIME Auction and the 
execution and allocation process is accelerated, prior to the end of 
the RFR period. The allocation process is not changed, and simple 
orders resting on the book that may be executed by way of Legging are 
still subject to complex order priority interest at each price point 
and are allocated contracts only after all complex interest at that 
price has been filled. The Exchange believes that it is consistent and 
equitable and not unfairly discriminatory to afford priority at each 
price point to complex interest over simple interest even when the 
cPRIME Auction ends early.
    The Exchange also believes that the proposed rule change removes 
impediments to and perfects the mechanisms of a free and open market 
and a national market system by attracting more order flow and by 
increasing the frequency with which Initiating Members initiate 
Auctions in complex orders through PRIME, using complex orders. 
Moreover, the proposed rule change is consistent with the rules of 
other exchanges.\60\

723, Supplementary Materials .09; Chicago Board Options Exchange,

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

B. Self-Regulatory Organization's Statement on Burden on Competition

    The Exchange does not believe that the proposed rule change will 
impose any burden on competition that is not necessary or appropriate 
in furtherance of the purposes of the Act.
    On the contrary, the proposed rule change is intended to promote 
competition by adding new order types that enable MIAX Options 
participants to execute complex orders on the Exchange. The Exchange 
believes that this enhances inter-market competition by enabling MIAX 
Options to compete for this type of order flow with other exchanges 
that have similar rules and functionalities in place.
    The Exchange further believes that adding complex orders to the 
PRIME mechanism enhances intra-market competition by adding another 
manner in which competing MIAX Options participants may submit 
competitive bids and offers into the System. This should result in 
enhanced liquidity and more competition on the Exchange.
    For all the reasons stated, the Exchange does not believe that the 
proposed rule change will impose any burden on competition not 
necessary or appropriate in furtherance of the purposes of the Act, and 
believes the proposed change will in fact enhance competition.
