April 6, 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 April 3, 2017, MIAX PEARL, LLC (“MIAX PEARL” or “Exchange”) filed with the Securities and Exchange Commission (“Commission”) a proposed rule change”) 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 Rules 504 and 516.
The text of the proposed rule change is available on the Exchange's Web site 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
The Exchange proposes to amend Exchange Rule 516, Order Types, to make changes to paragraph (j) related to Post-Only Order 
handling on the Exchange to simplify order entry and enhance liquidity available at the open. Additionally, the Exchange proposes to amend Exchange Rule 504, Trading Halts, to remove Interpretations and Policies .05.
Currently, by definition, Post-Only Orders on MIAX PEARL do not participate in the Opening Process,
and Post-Only Orders received before the Opening Process, during a trading halt, or after the market close, are rejected.
Additionally, Post-Only Orders that remain on the Book 
after a trading halt under Rule 504 are cancelled.
Post-Only Orders are designed to be liquidity providing orders, as a Post-Only Order by definition is one that will not remove liquidity from the Book.
The Exchange now proposes to amend certain aspects of its handling of Post-Only Orders to allow them to participate in the Opening Process and to also allow Post-Only Orders to be received by the Exchange prior to the commencement of the Opening Process or during a trading halt, and to remain on the Book after a trading halt, where they may participate in the next Opening Process.
The Exchange proposes to amend Exchange Rule 516 (j) to allow Post-Only Orders to participate in the Opening Process by ignoring the Post-Only instruction on the order during this period. This will allow Post-Only Orders to participate in the Opening Process by removing the prior restriction that a Post-Only Order not remove liquidity from the Book. As proposed, during the Opening Process, Post-Only Orders will be accepted and provide additional liquidity as orders are matched for execution based on price-time priority.
The Exchange believes that removing the prohibition against Post-Only Orders participating in the Opening Process will serve as a catalyst for Members 
to submit orders during the opening and improve the liquidity available during the Exchange's Opening Process which may also improve prices at the opening.
The Exchange has two classes of Members, Market Makers 
and Electronic Exchange Members.
Market Makers are the primary users of Post-Only Orders on the Exchange as discussed in more detail below. Currently, in order to provide liquidity during the Opening Process, Market Makers must use regular orders, as orders marked Post-Only will be rejected. After the Opening Process has concluded, Market Makers switch over to marking orders as Post-Only Orders. Market Makers use Post-Only Orders to provide two-sided quotes to meet their quoting obligations as described in more detail below. The Exchange believes that its proposal to accept Post-Only Orders before the Opening Process will simplify the operation of the Exchange and reduce complexity for Members that submit orders during the Opening Process and that switch to submitting Post-Only Orders during regular trading. Permitting Post-Only Orders to participate in the Opening will simplify the operational complexity for Market Makers that wish to provide liquidity during the Opening Process and thereby improve prices at the open.
Market Makers have a heightened obligation on the Exchange to maintain a two-sided market, pursuant to Rule 605(d)(1), in those option series in which the Market Maker has registered to trade.
Exchange Rule 605, Market Maker Quotations, details various requirements associated with a Market Start Printed Page 17701Maker's quotes, such as “Size Associated with Quotes”, “Firm Quotes”, and “Continuous Quotes”.
A quote on the Exchange is defined as, “. . . a bid or offer entered by a Market Maker as a firm order that updates the Market Maker's previous bid or offer, if any . . . .” 
The Exchange's definition of a quote further provides that, “[w]hen the term order is used in these Rules and a bid or offer is entered by the Market Maker in the option series to which such Market Maker is registered, such order shall, as applicable, constitute a quote or quotation for purposes of these Rules.” 
Market Makers self-assign the series for which they choose to act as a Market Maker and may register daily for these series.
A Market Maker could easily have an obligation to provide continuous quotes for a large number of series. Eliminating the need for Market Makers to switch from sending regular orders during the Opening Process to Post-Only Orders after the Opening Process is complete will allow Market Makers to more efficiently provide liquidity during the Opening Process and seamlessly transition to regular trading.
Additionally, the Exchange proposes to amend Rule 516(j) to state that Post-Only Orders are valid during the Opening Process and that Post-Only Orders received before the Opening Process or during a trading halt may participate in the next Opening Process. The Exchange notes that Post-Only Orders received after the market close will continue to be rejected.
At the completion of the Opening Process, the Exchange re-introduces orders that did not execute or that were priced through the Opening Price.
The Exchange now proposes to also re-introduce Post-Only Orders that participated in the Opening Process but were not executed. The Post-Only instruction on such re-introduced Post-Only Orders will be recognized and the orders will be treated in the same manner as Post-Only Orders received during a regular trading session, wherein such orders may not remove liquidity, in accordance with the existing rule.
Finally, Exchange Rule 504.05 currently provides that Post-Only Orders that are on the Book will be cancelled when trading in an option on a security has been halted pursuant to Rule 504. The Exchange now proposes to eliminate this paragraph in its entirety. As discussed above, the Exchange is proposing to amend its handling of Post-Only Orders and will include them in the Opening Process, therefore it is not necessary to remove Post-Only Orders from the Book when an option has been halted pursuant to Rule 504, as they may participate in the next Opening Process.
2. Statutory Basis
MIAX PEARL 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 the proposed rule change will simplify its market structure, minimize unnecessary complexity, and encourage liquidity during the Opening Process. The Exchange believes this change will make the transition from the opening to regular trading more efficient and thus promote just and equitable principles of trade and serve to protect investors and the public interest.
Additionally, the proposed rule change is consistent with the current rules of another options exchange.
B. Self-Regulatory Organization's Statement on Burden on Competition
The Exchange does not believe that the proposed rule change will impose any burden on competition that is not necessary or appropriate in furtherance of the purposes of the Act.
The Exchange does not believe that the proposed rule changes will impose any burden on intra-market competition as the Rules apply equally to all Exchange Members.
The Exchange does not believe that the proposed rule change will impose any burden on inter-market competition as the proposal is designed to simplify the complexity of order entry at the open, and could result in more competitive order flow to the Exchange at the open.
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.
