###### Securities and Exchange Commission

          - [Release No. 34-83731; File No. SR-GEMX-2018-26]

                    Pursuant to 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 July 16, 2018, Nasdaq GEMX, LLC (“GEMX” or “Exchange”) filed with the Securities and Exchange Commission (“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 codify the definitions of the protocols that Members can use to enter quotes and orders on the Exchange.

                    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

                    The purpose of the proposed rule change is to codify the definitions of the protocols that Members use to enter quotes and orders on the Exchange, specifically, the Specialized Quote Feed (“SQF”), Ouch to Trade Options (“OTTO”), Financial Information eXchange (“FIX”), and Nasdaq Precise (“Precise”). On April 27, 2017, the Exchange filed a proposed rule change that established the ports that Members use to connect to the Exchange, including ports used for quote and order entry—                    *i.e.,*                     SQF, OTTO and FIX.[3]                                          The Exchange has also filed proposed rule changes that briefly describe the availability of Precise, which is the Exchange's proprietary front-end interface used by Electronic Access Members (“EAMs”) and their Sponsored Customers [4]                                          to send orders to the                           ( print page 37868)                        Exchange and perform other related functions.[5]                                          The protocols used by Members to submit quotes and orders play an important role in the operation of the trading system as critical Exchange functionality used by Members to transact in options is offered through these protocols. The Exchange therefore believes that codifying definitions of these protocols in its rules will increase transparency around its operations.                

                    As it relates to FIX, OTTO, and SQF, the proposed language is substantially similar to the language included in SR-GEMX-2017-07 with changes to more clearly and accurately reflect the certain information included on each protocol, such as by separating out different categories of messages (                    *e.g.,*                     auction orders, auction notifications, and auction responses). Furthermore, the proposed definitions will be harmonized where appropriate with definitions to be included in the rules of the Exchange's affiliated options markets, including by using consistent terms to define the buckets of information transmitted, or the features available, on each protocol.[6]                                          Although the Exchange is changing how it categorizes various features included on FIX, OTTO, and SQF as part of its harmonization effort, the list of features included in the proposed definitions are intended to be exhaustive with respect to the buckets of information provided on each protocol. The Exchange also seeks to memorialize Precise to reflect the specific categories of features that are available on the Precise front-end today (                    *e.g.,*                     order and execution management, market data, and risk management). Overall, the Exchange believes that the proposed changes will allow Members to more easily understand what information is available on which protocol.                

                    As proposed, Supplementary Material .03 to Rule 715 (                    *i.e.,*                     Types of Orders) will provide that the Exchange offers Members the following protocols for entering orders and quotes respectively:                

### A. Financial Information eXchange Ports

                    When the Exchange initially filed to adopt order and quote entry protocols, it described the FIX protocol as follows: “FIX is an interface that allows market participants to connect and send orders and auction orders into the Exchange. Data includes the following: (1) Options Symbol Directory Messages; (2) System Event Messages (                    *e.g.,*                     start of messages, start of system hours, start of quoting, start of opening); (3) Option Trading Action Messages (                    *e.g.,*                     halts, resumes); (4) Execution Messages; (5) Order Messages (order messages, risk protection triggers or purge notifications).”                

The Exchange now proposes to codify the following definition of FIX in its rulebook: “Financial Information eXchange” or “FIX” is an interface that allows Members and their Sponsored Customers to connect, send, and receive messages related to orders and auction orders to the Exchange. Features include the following: (1) Execution messages; (2) order messages; (3) risk protection triggers and cancel notifications; and (4) post trade allocation messages.

### B. Ouch To Trade Options Ports

                    When the Exchange initially filed to adopt order and quote entry protocols, it described the OTTO protocol as follows: “OTTO is an interface that allows market participants to connect and send orders, auction orders and auction responses into the Exchange. Data includes the following: (1) Options Auction Notifications (                    *e.g.,*                     Flash, PIM, Solicitation and Facilitation or other information); (2) Options Symbol Directory Messages; (3) System Event Messages (                    *e.g.,*                     start of messages, start of system hours, start of quoting, start of opening); (5) Option Trading Action Messages (                    *e.g.,*                     halts, resumes); (6) Execution Messages; (7) Order Messages (order messages, risk protection triggers or purge notifications).”                

                    The Exchange now proposes to codify the following definition of OTTO in its rulebook: “Ouch to Trade Options” or “OTTO” is an interface that allows Members and their Sponsored Customers to connect, send, and receive messages related to orders, auction orders, and auction responses to the Exchange. Features include the following: (1) Options symbol directory messages (                    *e.g.,*                     underlying instruments); (2) system event messages (                    *e.g.,*                     start of trading hours messages and start of opening); (3) trading action messages (                    *e.g.,*                     halts and resumes); (4) execution messages; (5) order messages; (6) risk protection triggers and cancel notifications; (7) auction notifications; (8) auction responses; and (9) post trade allocation messages.                

### C. Specialized Quote Feed Ports

                    When the Exchange initially filed to adopt order and quote entry protocols, it described the SQF protocol as follows: “SQF is an interface that allows market makers to connect and send quotes, sweeps and auction responses into the Exchange. Data includes the following: (1) Options Auction Notifications (                    *e.g.,*                     opening imbalance, Flash, PIM, Solicitation and Facilitation or other information); (2) Options Symbol Directory Messages; (3) System Event Messages (                    *e.g.,*                     start of messages, start of system hours, start of quoting, start of opening); (4) Option Trading Action Messages (                    *e.g.,*                     halts, resumes); (5) Execution Messages; (6) Quote Messages (quote/sweep messages, risk protection triggers or purge notifications).”                

                    The Exchange now proposes to codify the following definition of SQF in its rulebook: “Specialized Quote Feed” or “SQF” is an interface that allows market makers to connect, send, and receive messages related to quotes, Immediate-or-Cancel Orders, and auction responses to the Exchange. Features include the following: (1) Options symbol directory messages (                    *e.g.,*                     underlying instruments); (2) system event messages (                    *e.g.,*                     start of trading hours messages and start of opening); (3) trading action messages (                    *e.g.,*                     halts and resumes); (4) execution messages; (5) quote messages; (6) Immediate-or-Cancel Order messages; (7) risk protection triggers and purge notifications; (8) opening imbalance messages; (9) auction notifications; and (10) auction responses. The SQF Purge Interface only receives and notifies of purge requests from the market maker.[7] 

### D. Nasdaq Precise

                    “Nasdaq Precise” or “Precise” is a front-end interface that allows Electronic Access Members and their Sponsored Customers to send orders to the Exchange and perform other related functions. Features include the following: (1) Order and execution management: Enter, modify, and cancel orders on the Exchange, and manage executions (                    *e.g.,*                     parent/child orders, inactive orders, and post-trade allocations); (2) market data: Access to real-time market data (                    *e.g.,*                     NBBO and                           ( print page 37869)                        Exchange BBO); (3) risk management: set customizable risk parameters (                    *e.g.,*                     kill switch); and (4) book keeping and reporting: comprehensive audit trail of orders and trades (                    *e.g.,*                     order history and done away trade reports).                

                    Precise is a software application that is offered by the Exchange to EAMs and their Sponsored Customers. Use of Precise is completely voluntary. The Exchange makes Precise available to EAMs and their Sponsored Customers as a convenience for entering and managing orders, but the protocol is not an exclusive means for any user to send orders to GEMX. Precise is merely a front-end interface to the Exchange's existing trading system, and is designed as an alternative to the Exchange's other protocols (                    *i.e.,*                     FIX, OTTO, and SQF) for the sending of orders to GEMX. Precise is also an alternative to similar front-end order and execution management systems currently offered by other technology providers as well as other exchanges.[8] 

                    Precise provides users with access to GEMX's regular order book. The protocol offers order and execution features that allow users to send, modify, and cancel their orders, and manage executions. For example, the protocol offers users the capability to stage larger orders and divide them into smaller orders for execution (                    *i.e.,*                     parent/child orders), or stage multiple orders to send for execution at a later time (                    *i.e.,*                     inactive orders). Precise also offers post trade allocation, including the capability for users to directly adjust clearing information on the front-end protocol. Precise users can also access and display real-time market data such as the National Best Bid and Offer (“NBBO”) and the Exchange Best Bid and Offer (“Exchange BBO”).                

                    Precise also provides risk management capabilities that allow users to set customizable risk parameters.[9]                                          For example, Precise supports the kill switch risk protection feature, which is an optional tool that enables members to initiate a message(s) to the Exchange's trading system to promptly cancel orders and restrict entry of new orders until re-entry has been enabled.[10]                                          Lastly, Precise provides a comprehensive audit trail of orders and trades through its book keeping and reporting features, including order history reports and done away trade reports.[11] 

#### 2. Statutory Basis

                    The Exchange believes that the proposed rule change is consistent with Section 6(b) of the Securities Exchange Act of 1934 (the “Act”),[12]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act,[13]                                          in particular, in that it is designed to promote just and equitable principles of trade, to remove impediments to and perfect the mechanism for 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 is consistent with the protection of investors and the public interest as it codifies the protocols used to connect to the Exchange's trading system. As discussed above, the Exchange previously filed to establish FIX, OTTO, and SQF in SR-GEMX-2017-07. These protocols will now be codified in the Exchange's rulebook. In addition, the Exchange has briefly described Precise in various proposed rule changes filed with the Commission. In the interest of transparency, the Exchange has included a more fulsome description of the functionalities offered via Precise in this proposed rule change, and is codifying language in its rules that would describe this protocol.

While no functional changes to the protocols are proposed in this filing, the Exchange believes that including a description of the protocols in its rulebook will benefit Members by increasing transparency around the operation of the Exchange. Furthermore, the proposed definitions being included in the rulebook will more clearly and accurately reflect the information included on the protocols, and will be harmonized with language to be included in the rules of its affiliated exchanges to the extent that the protocols operate in the same manner. The protocols described in this filing provide a range of important features to Members, including the ability to submit quotes and orders, and perform other functions necessary to manage trading on the Exchange. The Exchange believes codifying the quote and order entry protocols will increase transparency to the Members that use these protocols to connect to the Exchange.

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

                    In accordance with Section 6(b)(8) of the Act,[14]                                          the Exchange 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. As explained above, the Exchange is codifying the quote and order entry protocols that Members use to connect to the Exchange's trading system. The Exchange does not believe that codifying these protocols in the rulebook will have any competitive impact. FIX, OTTO, and SQF were established in SR-GEMX-2017-07, and are already available to Members, who use these protocols to connect and manage their trading activity on the Exchange. Adding rule language that describes these Exchange offerings will increase transparency around the operation of the Exchange without having any impact on intermarket or intramarket competition. Furthermore, Precise is a voluntary piece of functionality that EAMs and their Sponsored Customers may use as a convenience for entering and managing orders and executions, as an alternative to the Exchange's other protocols (                    *i.e.,*                     FIX, OTTO, and SQF). Precise is also an alternative to similar front-end order and execution management systems currently offered by other technology providers as well as other exchanges (                    *e.g.,*                     PULSe). If market participants believe that other products available in the marketplace are more beneficial than Precise, they will simply use those products instead. For the foregoing reasons, the Exchange does not believe that its proposal to codify Precise will impose any burden on intermarket or intramarket competition that is not necessary or appropriate in furtherance of the purposes of the Act.                

### 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.                          ( print page 37870)    

## 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 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)(iii) of the Act [15]                                          and subparagraph (f)(6) of Rule 19b-4 thereunder.[16] 

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: (i) Necessary or appropriate in the public interest; (ii) for the protection of investors; or (iii) 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.
