On February 21, 2019, Cboe EDGX Exchange, Inc. (the “Exchange”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) ^[1] and Rule 19b-4 thereunder,^[2] a proposed rule change to adopt Rule 21.21, the Solicitation Auction Mechanism, a solicited order mechanism for larger-sized orders. The proposed rule change was published for comment in the Federal Register on March 12, 2019.^[3] On April 23, 2019, the Exchange filed Amendment No. 1 to the proposed rule change.^[4] The Commission has received no comments on the proposal.

Section 19(b)(2) of the Act ^[5] provides that within 45 days of the publication of notice of the filing of a proposed rule change, or within such longer period up to 90 days as the Commission may designate if it finds such longer period to be appropriate and publishes its reasons for so finding or as to which the self-regulatory organization consents, the Commission shall either approve the proposed rule change, disapprove the proposed rule change, or institute proceedings to determine whether the proposed rule change should be disapproved. The 45th day for this filing is April 26, 2019.

The Commission is extending the 45-day time period for Commission action on the proposed rule change, as modified by Amendment No. 1. The Commission finds that it is appropriate to designate a longer period within which to take action on the proposed rule change so that it has sufficient time to consider the proposed rule change, as modified by Amendment No. 1.

Accordingly, pursuant to Section 19(b)(2) of the Act,^[6] the Commission designates June 10, 2019, as the date by which the Commission shall either approve or disapprove, or institute proceedings to determine whether to disapprove, the proposed rule change, as modified by Amendment No. 1 (File No. SR-CboeEDGX-2019-009).
