                    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”),[1]                                          and Rule 19b-4 thereunder,[2]                                          notice is hereby given that on July 5, 2018, Nasdaq GEMX, LLC (“GEMX” or “Exchange”) filed with the Securities and Exchange Commission (“SEC” or “Commission”) the proposed rule change as described in Items I and II 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 proposes to amend GEMX Rule 723, entitled “Price Improvement Mechanism for Crossing Transactions.”

                    The text of the proposed rule change is available on the Exchange's website at                     *http://nasdaqgemx.cchwallstreet.com/​,*                     at the principal office of the Exchange, 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

                    GEMX proposes to amend Rule 723, entitled “Price Improvement Mechanism for Crossing Transactions.” Specifically, the Exchange proposes to amend Rule 723(c)(2) to expand the types of Improvement Orders [3]                                          that may be entered into the Price Improvement Mechanism or “PIM.” The Exchange also proposes to amend Rule 723(d)(1)-(3) to more specifically clarify terms such as “orders” and “responses” in that section.                

#### Background

                    The Exchange adopted PIM as part of its application to be registered as a national securities exchange under its previous name of Topaz Exchange, LLC.[4]                                          In approving PIM, the Commission noted that it was largely based on a similar functionality offered by the International Securities Exchange, LLC (now Nasdaq ISE, LLC) (“ISE”).[5]                                          ISE received approval to establish its PIM in 2004 that would allow an ISE Electronic Access Member (“EAM”) to enter matched trades (“Crossing Transactions”).[6]                                          As noted in the Adopting Filing, a Crossing Transaction would be comprised of an order that the EAM represents as agent (“Agency Order”) and an order that is executable against the Agency Order for the full size of the Agency Order (the “Counter-Side Order”).[7]                                          In the Adopting Filing, ISE specified in Rule 723(c)(2) that Improvement Orders may be for the account of a Public Customer or for the Member's own account.[8]                                          The Adopting Filing noted that ISE would broadcast Crossing Orders to all Members.[9]                                          Further, it was noted in the Adopting Filing that during a three second auction, all ISE Members could enter “Improvement Orders,” in penny increments, to improve the price of the Agency Order.[10]                                          The Adopting Filing stated that Improvement Orders may be for the account of a Public Customer or for the Member's own account.[11]                                          Finally, the Adopting Filing noted that during the exposure period, the aggregate size of the best prices, including the Counter-Side Order, Improvement Orders, and any change to either, would continually be updated and broadcast to all Members.[12] 

#### Rule 723(c)(2)

With respect to the current limitation of Improvement Orders for the account of a Public Customer or for the Member's own account, ISE noted in its Adopting Filing that “all ISE Members would be permitted to participate in a PIM . . . unrelated orders could compete in standard increments to trade with the Agency Order in the PIM. Such unrelated orders could include agency orders on behalf of Public Customers, market makers on other exchanges, and non-ISE member broker-dealers, as well as non-Improvement orders submitted by ISE members.”

                    At this time, the Exchange proposes to permit any GEMX Member to enter an Improvement Order marked as a response to a PIM auction similar to Nasdaq PHLX LLC (“Phlx”) [13]                                          and Nasdaq BX, Inc. (“BX”) [14]                                          rules. The Exchange no longer desires to limit Members who may enter Improvement Orders into PIM to simply those orders for the account of a Public Customer or for the Member's own account. The Exchange desires to expand the types of orders that may be entered as Improvement Orders similar to Phlx and BX. The Exchange is therefore removing this limitation in Rule 723(c)(2) so that the proposed rule text would read: “Improvement Orders may be entered by all Members in one-cent increments at the same price as the Crossing Transaction or at an improved price for the Agency Order, and for any size up to the size of the Agency Order.”                

#### Rule 723(d)(1)-(3)

                    The Exchange proposes to amend GEMX Rule 723(d)(1)-(3), which                           ( print page 34624)                        explains the manner in which a PIM Order shall be allocated to conform this text to the change which is proposed in Rule 723(c)(2). Rule 723(d)(1) currently provides, “At a given price, Priority Customer interest is executed in full before Professional Orders [15]                                          and any other interest of Members (                    *i.e.,*                     proprietary interest from Electronic Access Members and Exchange market makers).” The Exchange proposes to expand upon the term interest by adopting the defined terms “Priority Customer Interest” for Priority Customer Orders and Improvement Orders from Priority Customers, and “Professional Interest” for Professional Orders, Improvement Orders from non-Priority Customers, and Market Maker quotes. The Exchange believes that adding these defined terms would clarify what is meant by interest. As proposed, Professional Interest identifies all orders (including Improvement Orders) that are not for the account of a Priority Customer as well as Market Maker quotes, thereby incorporating the current reference to “Professional Orders” within its terms and eliminating the necessity to include the current rule text which provides, “any other interest of Members (                    *i.e.,*                     proprietary interest from Electronic Access Members and Exchange market makers).”                

The Exchange proposes to amend Rule 723(d)(2) which currently provides, “After Priority Customer interest at a given price, Professional Orders and Members' interest will participate in the execution of the Agency Order based upon the percentage of the total number of contracts available at the price that is represented by the size of the Members' interest.” The Exchange proposes to replace the reference to “Priority Customer interest” with the defined term “Priority Customer Interest” proposed to be added in Rule 723(d)(1), as described above. The Exchange also proposes to change “Professional Orders” to “Professional Interest” which will be defined in Rule 723(d)(1) to include Professional Orders as well as Improvement Orders from non-Priority Customers and Market Maker quotes. Since Professional Interest is defined in this manner, the Exchange also proposes to remove the language referring to “Members' interest” from the sentence because Professional Interest would include all orders from non-Priority Customers and Market Maker quotes.

                    The Exchange proposes to amend Rule 723(d)(3) to again remove the rule text relating to “Members' interest” and instead utilize the defined “Professional Interest” term consistent with proposed changes to Rule 723(d)(1) and (2). The Exchange also proposes to make similar changes to add the term “Professional Interest” to the sentence in Rule 723(d)(3) that currently reads: “Thereafter, all other orders, Responses, and quotes at the price point will participate in the execution of the Agency Order based upon the percentage of the total number of contracts available at the price that is represented by the size of the order, Response or quote.” In particular, the language related to “other orders, Responses, and quotes” in this sentence will be replaced with “Professional Interest” since this term includes all orders from non-Priority Customers and Market Maker quotes, as described above. The Exchange notes that the references in this sentence to “Responses,” currently an undefined term, should instead refer to the defined term “Improvement Orders,” and the proposed changes should therefore clarify how Rule 723(d)(3) will apply. Finally, the Exchange proposes to replace the word “Priority Customer Orders” with “Priority Customer Interest” as defined in proposed Rule 723(d)(1) to clarify that those orders as well as responses (                    *i.e.,*                     Improvement Orders from Priority Customers) are applicable. The proposed amendments add more specificity to the exact order/quotes and responses which apply in this section.                

The amendments to Rule 723(d)(1)-(3) conform to the proposed amendment to Rule 723(c)(2) and other proposed amendments as described above which do not change the manner in which PIM operates today, rather the other word changes seek to bring specificity to the manner in which order, quotes and responses are treated.

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with Section 6(b) of the Act,[16]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act,[17]                                          in particular, in that it is designed to promote just and equitable principles of trade, 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.                

The Exchange's proposal to amend Rule 723(c)(2) seeks to broaden the types of orders that may be submitted as Improvement Orders into PIM. As ISE previously noted, in its Adopting Filing, all Members are able to participate in a PIM today as an unrelated order that rests on the Order Book. Unrelated orders that rest on the Order Book can participate in PIM and trade with the Agency Order in the PIM. The Exchange proposes to allow all Members to submit Improvement Orders directly into PIM to provide an even greater number of GEMX Members to more directly participate in PIM and provide price improvement. The Exchange's proposal is consistent with the Act because allowing a greater number of Members to directly respond with an Improvement Order in a PIM will increase the likelihood of price improvement in that auction thereby removing impediments to and perfecting the mechanism of a free and open market and a national market system. This approach will enable greater participation in PIM auctions.

The Exchange's proposal to amend Rule 723(d) conforms the text with changes made with respect to the proposal to amend Rule 723(c)(2) for consistency. The proposed changes to remove the more generic “Members' interest” and instead substitute very specific terms to define interest and add quotes provide more specificity as to the manner in which interest entered into PIM will be allocated. The Exchange's proposed amendments to Rule 723(d)(1)-(3) are consistent with the Act because the amendments seek to conform the rule text to the proposed Rule 723(c)(2) amendment and describe in greater detail how interest will be allocated by defining terms and eligible interest and this transparency benefits investors and the public interest.

### 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 not necessary or appropriate in furtherance of the purposes of the Act. The Exchange's proposal to amend Rule 723(c)(2) to broaden the types of orders that may be submitted as Improvement Orders into PIM does not unduly burden competition because all Members will be permitted to submit Improvement Orders directly into PIM to provide an even greater number of GEMX Members to more directly participate in PIM. The amendments to Rule 723(d) will conform the rule text and bring clarity to the allocation method for PIM.                          ( print page 34625)    

### C. Self-Regulatory Organization's Statement on Comments on the Proposed Rule Change Received From Members, Participants, or Others

No written comments were either solicited or received.

## III. Date of Effectiveness of the Proposed Rule Change and Timing for Commission Action

                    Because the 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 from the date on which it was filed, or such shorter time as the Commission may designate, it has become effective pursuant to Section 19(b)(3)(A) of the Act [18]                                          and Rule 19b-4(f)(6) thereunder.[19] 

                    A proposed rule change filed pursuant to Rule 19b-4(f)(6) under the Act [20]                                          normally does not become operative for 30 days after the date of its filing. However, Rule 19b-4(f)(6)(iii) [21]                                          permits the Commission to designate a shorter time if such action is consistent with the protection of investors and the public interest. The Exchange has asked the Commission to waive the 30-day operative delay so that it may allow all Members to submit Improvement Orders directly into PIM to provide an even greater number of GEMX Members an opportunity to more directly participate in PIM and provide price improvement. The Exchange states that it will issue an Options Trader Alert to notify Members of the date within which this functionality will be implemented. The Commission believes the waiver of the operative delay is consistent with the protection of investors and the public interest. Accordingly, the Commission hereby waives the operative delay and designates the proposed rule change operative upon filing.[22] 

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.
