July 11, 2017.
Pursuant to the provisions of Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) 
and Rule 19b-4 thereunder,
notice is hereby given that, on June 28, 2017, Miami International Securities Exchange, LLC (“MIAX Options” or the “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 publishing this notice to solicit comments on the proposed rule change from interested persons.
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 Rule 524, Reporting of Matched Trades to Clearing Corporation.
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 the Statutory Basis for, the Proposed Rule Change
The Exchange proposes to amend Exchange Rule 524, Reporting of Matched Trades to Clearing Corporation, to adopt Interpretations and Policies .01, to state that post-trade adjustments that do not affect the contractual terms of a trade are to be performed by the Exchange Member 
via an Exchange approved electronic interface. The Exchange will notify Members of the approved electronic interface via Regulatory Circular.
The Exchange staffs a Help Desk 
to provide customer service and support to its Members. One of the support functions the Help Desk currently provides is to make certain post-trade adjustments to a Member's matched trades at the Member's request and on its behalf. The Exchange has also developed functionality that it makes available to all Members that enables Members to electronically and independently perform post-trade adjustments that do not affect the contractual terms of the transaction to their side of the matched trade. Start Printed Page 32744Examples of post-trade adjustments that do not affect the contractual terms of a trade include: changing the position indicator (e.g., from Open to Close or Close to Open); adding or removing Clearing Member Trade Agreement (“CMTA”) information; changing the clearing account type (e.g., Customer or Firm); and modifying the optional data field, which may be used by Members for their own internal back-office processing.
Despite the availability of functionality for Members to perform these straightforward post-trade adjustments on their own, the Help Desk still receives a significant number of requests on a daily basis to manually perform these adjustments. Processing these requests is a time consuming exercise for Exchange staff and is an inefficient use of Exchange time and resources given that Members have the ability to perform these adjustments themselves electronically via an Exchange provided interface. Accordingly, the Exchange proposes to mandate that Members perform their own post-trade adjustments which do not affect the contractual terms of a trade as discussed above, using the functionality provided by the Exchange. The Exchange notes that use of the functionality provided by the Exchange does not relieve Members of their obligations to abide by the rules of the Exchange.
The Exchange also represents that it has an adequate surveillance program in place to review post-trade adjustments made by its Members. Additionally, the Exchange has a Regulatory Services Agreement in place with the Financial Industry Regulatory Authority to monitor adjustments done directly at the Options Clearing Corporation (“OCC”) to ensure compliance with applicable Exchange rules and such Securities and Exchange Commission Trading rules related to options trading. Further, the Exchange notes that Members may make post-trade adjustments to trades executed on the Exchange directly at the OCC, as the OCC provides functionality for Members to update certain non-critical trade information with respect to the transaction, provided such changes are not in contravention of any rule of the Exchange on which a confirmed trade was executed.
The Exchange notes that other exchanges offer similar functionality to their members for post-trade adjustments.
However, these Exchanges incentivize their members to perform their own post-trade adjustments by charging a fee when the member elects to have the exchange perform the adjustment on their behalf, as opposed to mandating usage of an interface to perform post-trade adjustments such as the Exchange is proposing.
2. Statutory Basis
MIAX believes that its proposed rule change is consistent with Section 6(b) of the Act 
in general, and furthers the objectives of Section 6(b)(5) of the Act 
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 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.
The Exchange believes that its proposal would promote just and equitable principles of trade and not unfairly discriminate between Members because the functionality to make post-trade adjustments is available to all Members. Further, the Exchange believes that its proposal would promote a fair and orderly market and protect investors and the public interest because its proposal would result in a more efficient use of Exchange resources, which would benefit all market participants.
B. Self-Regulatory Organization's Statement on Burden on Competition
The Exchange does not believe that the proposed rule change will result in any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed rule change is not designed to address any competitive issues but rather to make more efficient use of the Exchange's employee time and resources, which may ultimately benefit Members.
The Exchange does not believe that the proposed rule change will impose any burden on intra-market competition as the Rules apply equally to all Exchange Members.
C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others
Written comments were neither solicited nor received.
III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action
Because the foregoing proposed rule change does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) become operative for 30 days after the date of the filing, or such shorter time as the Commission may designate, it has become effective pursuant to 19(b)(3)(A) of the Act 
and Rule 19b-4(f)(6) 
At any time within 60 days of the filing of the proposed rule change, the Commission summarily may temporarily suspend such rule change if it appears to the Commission that such action is necessary or appropriate in the public interest, for the protection of investors, or otherwise in furtherance of the purposes of the Act. If the Commission takes such action, the Commission shall institute proceedings to determine whether the proposed rule should be approved or disapproved.
IV. Solicitation of Comments
Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act. Comments may be submitted by any of the following methods:
