On April 25, 2017, Miami International Securities Exchange LLC (“MIAX Options” or the “Exchange”) 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 amend MIAX Options Rule 515A to modify the exposure periods of the Exchange's Price Improvement Mechanism (“PRIME”) and PRIME Solicitation Mechanism from 500 milliseconds to a time period designated by the Exchange of no less than 100 milliseconds and no more than 1 second. The proposed rule change was published for comment in the Federal Register on May 5, 2017. The Commission received no comment letters on the proposed rule change. This order approves the proposed rule change.
II. Description of the Proposed Rule Change
PRIME is a process by which a Member  may electronically submit for execution an order it represents as agent (“Agency Order”) against principal interest, and/or an Agency Order against solicited interest. When the Exchange receives a properly designated Agency Order for auction processing, a Request for Responses (“RFR”) detailing the option, side, size, and initiating price is sent to all subscribers of the Exchange's data feeds. Currently, the RFR period lasts for 500 milliseconds, unless it is concluded early. The Exchange proposes to revise the RFR response period to permit the Exchange to designate a specific time within a range of no less than 100 milliseconds and no more than 1 second.
III. Discussion and Commission's Findings
After careful review, the Commission finds that the proposed rule change is consistent with the requirements of the Act and the rules and regulations thereunder applicable to a national securities exchange. In particular, the Commission finds that the proposed rule change is consistent with Section 6(b)(5) of the Act, which requires, among other things, that the rules of a national securities exchange be designed to promote just and equitable principles of trade, to foster cooperation and coordination with persons engaged in regulating transactions in securities, to remove impediments to and perfect the mechanism of a free and open market and a national market system and, in general, to protect investors and the public interest, and not be designed to permit unfair discrimination between customers, issuers, brokers, or dealers. The Commission also finds that the proposed rule change is consistent with Section 6(b)(8) of the Act, which requires that the rules of an exchange not impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.
The Commission believes that, given the electronic nature of the PRIME and PRIME Solicitation Mechanism and the ability of Members to respond within the proposed exposure periods, modifying each of the exposure periods from 500 milliseconds to a time designated by the Exchange of no less than 100 milliseconds and no more than 1 second could facilitate the prompt execution of orders, while continuing to provide market participants with an opportunity to compete to trade with the exposed order by submitting responses to the auctions. According to the Exchange, numerous Members have the capability to and do respond within a 100 millisecond exposure period or less.
To substantiate that its members can receive, process, and communicate a response back to the Exchange within 100 milliseconds, the Exchange states that it surveyed all Members that responded to an auction broadcast in the period beginning November 2016 and ending January 2017 (the “review period”). According to the Exchange, each Member it surveyed indicated that they can receive, process, and communicate a response back to the Exchange within 100 milliseconds. In addition, the Exchange states that it reviewed all responses received in PRIME and PRIME Solicitation Auctions from its Members for the review period, and its review indicated that approximately 90% of responses were submitted within 100 milliseconds. Furthermore, with regard to the impact of the proposal on system capacity, the Exchange states that it has analyzed its capacity and represents that it has the necessary systems capacity to handle the potential additional traffic associated with the additional transactions that may occur with the Start Printed Page 28370implementation of the proposed reduction response time duration to no less than 100 milliseconds. The Exchange also represents that its system will be able to sufficiently maintain an audit trail for order and trade information with the reduction in the response timer.
Based on the Exchange's statements, the Commission believes that market participants should continue to have opportunities to compete to trade with the exposed order by submitting responses to the PRIME and PRIME Solicitation Mechanism within an exposure period of no less than 100 milliseconds and no more than 1 second. Accordingly, for the reasons discussed above, the Commission believes that the Exchange's proposal is consistent with the Act.
It is therefore ordered, pursuant to Section 19(b)(2) of the Act, that the proposed rule change (SR-MIAX-2017-16) be, and hereby is, approved.Start Signature
