###### Securities and Exchange Commission

          - [Release No. 34-83835; File No. SR-PEARL-2018-15]

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 August 1, 2018, MIAX PEARL, LLC (“MIAX PEARL” 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 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 514, Priority on the Exchange.

The text of the proposed rule change is available on the Exchange's website at *http://www.miaxoptions.com/​rule-filings/​pearl* at MIAX PEARL'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 Rule 514, Priority on the Exchange. Specifically, the Exchange proposes to amend subsection (c), Self-Trade Protection, to broaden the protection afforded under the current rule by giving Members [3]            the option to have this protection apply at the market participant identifier (“MPID”) [4]            level (*i.e.,* currently existing functionality), or at the firm level. The Exchange believes that this enhancement will provide helpful flexibility for market making firms that wish to prevent trading against all orders entered by their firm under any MPID, instead of just those entered under the same MPID.

Currently, the rule prevents orders entered by a Market Maker [5]            via the MEO Interface [6]            or the FIX Interface [7]            using the same MPID from executing against orders entered on the opposite side of the market by the same Market Maker using the same MPID via the MEO Interface or the FIX Interface.[8]            In such a case, the System [9]            will cancel the oldest of the orders back to the entering party prior to execution.

Members of the Exchange may either be Market Makers or Electronic Exchange Members.[10]            Each Market Maker and Electronic Exchange Member is assigned an MPID by the Exchange for identification purposes. A Member may have multiple Market Maker MPIDs on the Exchange, therefore the possibility exists that a Member may cross its own Market Maker's orders.[11] 

The Exchange now proposes to allow members to choose to have this protection applied at either the MPID level, as currently implemented, or at the member firm level. If members choose to have this protection applied at the member firm level, the System will prohibit orders entered from different MPIDs within the Member's firm from trading against one another. The Exchange believes that the proposed enhancement will provide Members with more tailored self-trade functionality that will allow Members to manage their trading as appropriate based on the Member's business needs. While the Exchange believes that some firms will want to restrict trading interest from the same MPID, (as currently implemented), the Exchange believes that other firms will find it helpful to apply self-trade protection across all MPIDs of the same firm.

The Exchange note that similar functionality also exists on the Nasdaq Stock Market (“NASDAQ”) which prevents self-trades by MPID, or alternatively, if selected by the member, self-trade protection for all MPIDs of the firm.[12]            Cboe BZX Exchange (“CboeBZX”) also has a similar rule in place which provides members the ability to apply Match Trade Prevention (“MTP”) modifiers (CboeBZX's version       ( print page 41127)    of self-trade protection) based on MPID, Exchange Member, trading group, or Exchange Sponsored Participant identifiers.[13] 

The Exchange will announce the implementation date of this functionality via a Regulatory Circular prior to the functionality being available on the Exchange.

#### 2.  Statutory Basis 

MIAX PEARL believes that its proposed rule changes are consistent with Section 6(b) of the Act [14]            in general, and furthers the objectives of Section 6(b)(5) of the Act [15]            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 the proposed changes promote just and equitable principles of trade, remove impediments to and perfect the mechanism of a free and open market and a national market system by providing Market Makers with additional flexibility to configure self-trade protections offered by the Exchange. Currently, all Market Makers are provided functionality that prevents orders entered by a Market Maker via the MEO Interface or the FIX Interface using the same MPID from executing against orders entered on the opposite side of the market by the same Market Maker using the same MPID via the MEO Interface or the FIX Interface. While this functionality is helpful, some members would prefer not to trade with orders entered under different MPIDs of the same firm. Therefore, the Exchange is proposing to provide Exchange Members flexibility with respect to how self-trade protections are implemented. Members may continue to use the current functionality, while members who prefer to prevent self-trades across different MPIDs within the same firm will now be provided with functionality that allows them to do so.

Similar functionality exists on the Nasdaq Stock Market and CboeBZX [16]            and the Exchange believes that the flexibility to apply self-trade protection at either the MPID or firm level would be useful to Members of MIAX PEARL. The Exchange also believes that the proposed rule change is designed to promote just and equitable principles of trade and will remove impediments to and perfect the mechanisms of a free and open market as it will enhance self-trade protections provided to MIAX PEARL Market Makers similar to those protections provided on other markets.

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

MIAX PEARL does not believe that the proposed rule change will impose any burden on intermarket or intramarket competition that is not necessary or appropriate in furtherance of the purposes of the Act. The proposed rule change is designed to enhance the Exchange's current self-trade protection, and will benefit members that wish to protect their orders from trading with orders from other Market Makers within the same firm, rather than the more limited MPID standard currently in use. The new functionality, which is similar to functionality already provided on CboeBZX, is also completely voluntary, and members that wish to use the current functionality may continue to do so. The Exchange does not believe that providing more flexibility to members will have any significant impact on competition. Conversely, the Exchange believes that the proposed rule change will foster competition as Market Makers may send more orders to the Exchange knowing that there is no chance that they will trade with their own orders on the other side of the market. This could result in more order flow and more liquidity on the Exchange.

The Exchange does not believe that the proposed rule change will impose any burden on intra-market competition as self-trade protection is available to all Market Makers on the Exchange. Further, the Exchange does not believe that the proposed rule change will impose any burden on inter-market competition, and rather could potentially promote inter-market competition and result in more competitive order flow to the Exchange by more widely preventing Market Makers from trading with their own orders.

### 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 [17]            and Rule 19b-4(f)(6) [18]            thereunder.

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:
