###### Securities and Exchange Commission

          - [Release No. 34-83368; File No. SR-MRX-2018-17]

      ( print page 26715)    
                    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 May 22, 2018, Nasdaq MRX, LLC (“MRX” 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 amend and reorganize Chapters II, IV, V, and VI of the MRX Schedule of Fees.

                    The text of the proposed rule change is available on the Exchange's website at                     *http://nasdaqmrx.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 Exchange proposes to amend Chapters II, IV, V, and VI of the MRX Schedule of Fees to: (i) Eliminate the Table of Contents; (ii) remove the INET Port Fees from Chapter II, Part B; (iii) adopt a new Chapter IV, entitled “Ports and Other Services” and amend and reorganize the current port fees; (iv) adopt a new Chapter V, entitled “Market Data” and list all the market data feeds; and (v) renumber Chapter IV, entitled “Connectivity Fees.” Each change will be described in more detail below. The Exchange believes that the proposed amendments to the Schedule of Fees will provide more clarity as to the current fees. The Exchange notes that no fee changes are being introduced in this rule change. The Exchange is simply reorganizing its rules to conform to other Nasdaq affiliate markets by aligning the location and description of its rules on each market.

#### Table of Contents

                    The Exchange proposes to eliminate the Table of Contents in the MRX Schedule of Fees. The Table of Contents are unnecessary. The website where the MRX rules are listed [3]                                          contains hyperlinks and a skeleton of the available rules within the site and enables market participants to view all rules in that section.                

#### INET Port Fees

The Exchange currently lists all INET Port Fees within Chapter II, Part C. The Exchange proposes to delete this rule text and relocate it to proposed new Chapter IV and entitle that chapter as “Ports and Other Services.” The Exchange believes that this title more accurately describes the types of fees contained in this chapter. The Exchange proposes to restructure the port fees. First, the Exchange proposes to add language at the beginning of this new chapter to state, “The below charges are assessed by MRX for connectivity to MRX.” The Exchange believes that this sentence makes clear that the fees apply to MRX. The Exchange proposes to define a port as “a logical connection or session that enables a market participant to send inbound messages and/or receive outbound messages from the Exchange using various communication protocols.” The Exchange believes this definition will assist members in distinguishing ports from other offerings.

                    The Exchange proposes to restructure the port fees into 4 categories. The Exchange proposes to list order and quote protocols first, order and execution offerings next, followed by data ports and other ports as the last section. The Exchange proposes to list data offerings that are offered at no cost. The Exchange believes that aligning its offerings, where relevant, with other affiliated markets [4]                                          will provide more transparency as to the offerings for market participants.                

The Exchange proposes to add a new section (i) and include the following introductory sentence, “The following order and quote protocols are available on MRX.” The Exchange proposes to list the order entry protocol port fees for FIX, SQF, SQF Purge Port and OTTO in this section. The fees are not being amended, the existing fees are being relocated into new section (i).

                    The Exchange proposes to add a new section (ii) and include the following introductory sentence, “The following order and execution information is available to Members.” The Exchange intends to list other port or interface information into this section that are available to MRX Members. The Exchange is relocating the CTI and FIX DROP port fees. No changes are being made to those fees. The Exchange also proposes to list TradeInfo MRX Interface into this section. The Exchange has recently filed to establish this Interface within the MRX rules.[5]                                          The Exchange proposes to note this interface is available on MRX at no cost.                

The Exchange proposes to add a new section (iii) and include the following language, “The following data port fees apply in connection with data subscriptions pursuant to MRX Rules at Chapter V. These ports are available to non-MRX Members and MRX Members.” Today, MRX does not assess a fee for these ports outlined in new section (iii). Similar to other Nasdaq Affiliated Markets the Exchange proposes to list all of the ports that Members and Non-Members obtain today at no cost. The Exchange believes that listing these ports in addition to the data subscriptions will bring more transparency to the Schedule of Fees.

The Exchange proposes to add a new section (iv) entitled “Other ports” and relocate the Disaster Recovery Ports into this section. The Exchange also proposes to make clear that a Disaster Recovery Port is available for any port listed in proposed sections (i)-(iii).

#### Market Data

                    The Exchange proposes to adopt a new Chapter V and entitle this section Market Data. Today, MRX does not assess fees for Market Data. The                           ( print page 26716)                        Exchange proposes to list its Market Data within Chapter V and note that there is no cost. The Exchange's Market Data fees are listed in Rule 718. The Exchange has listed these feeds within Chapter V to bring more transparency to the Schedule of Fees. Finally, the Exchange proposes to renumber Chapter IV, Connectivity Fees as new Chapter VI to account for the two new chapters proposed for the Rulebook.                

#### 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”),[6]                                          in general, and furthers the objectives of Section 6(b)(5) of the Act,[7]                                          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, by providing greater transparency as to the ports offered on MRX.                

The Exchange's proposal to remove the Table of Contents, relocate the INET Fees, retitle and restructure those fees and adopt a new Market Data section at Chapter V are administrative. These changes are consistent with the protection of investor and the public interest because the amendments are intended to bring greater clarity to the Rulebook. The Exchange's proposal to reorganize the port fees into sections and include pricing for ports that are offered at no cost is also consistent with the protection of investor and the public interest because it will bring greater transparency to the Exchange's current offerings. The Exchange's proposal to display the various market data within newly proposed Chapter V will also bring greater transparency to the Exchange's current offerings.

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

                    In accordance with Section 6(b)(8) of the Act,[8]                                          the Exchange does not believe that the proposed rule change will impose any burden on intermarket or intra-market competition that is not necessary or appropriate in furtherance of the purposes of the Act. The Exchange's proposal does not impose an undue burden on competition, rather the Exchange is seeking to provide greater transparency within its rules with respect to the various ports and market data offered on MRX.                

### 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 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 [9]                                          and subparagraph (f)(6) of Rule 19b-4 thereunder.[10] 

                    A proposed rule change filed under Rule 19b-4(f)(6) [11]                                          normally does not become operative prior to 30 days after the date of the filing. However, Rule 19b-4(f)(6)(iii) [12]                                          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 the proposed rule change may become effective and operative immediately upon filing. The Exchange states that it believes the waiver will further the protection of investors and the public interest because it will provide greater transparency as to various ports available to market participants. The Exchange further states that the proposed rule change will bring greater clarity to the Schedule of Fees. The Commission believes that waiver of the 30-day operative delay is consistent with the protection of investors and the public interest. Therefore, the Commission hereby waives the 30-day operative delay and designates the proposed rule change as operative upon filing.[13] 

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.
