Self-Regulatory Organizations; Bats EDGX Exchange, Inc.; Notice of Designation of Longer Period for Commission Action on Proposed Rule Change To Adopt New Rules That Describe the Trading of Complex Orders on the Exchange

On June 30, 2017, Bats EDGX Exchange, Inc. (the “Exchange” or “EDGX”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) and Rule 19b-4 thereunder, a proposed rule change to adopt new rules that describe the trading of complex orders on the Exchange's equity options platform. The proposed rule change was published for comment in the Federal Register on July 19, 2017. The Commission has received no comment letters regarding the proposal.

Section 19(b)(2) of the Act 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 September 2, 2017.

The Commission is extending the 45-day time period for Commission action on the proposed rule change. 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 and take action on the Exchange's proposed rule change.

Accordingly, pursuant to Section 19(b)(2) of the Act and for the reasons stated above, the Commission designates October 17, 2017, as the date by which the Commission should either approve or disapprove, or institute proceedings to determine whether to disapprove, the proposed rule change (File No. SR-BatsEDGX-2017-29).
