###### Securities and Exchange Commission

          - [Release No. 34-83782; File No. SR-CBOE-2018-053]

                    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 31, 2018, Cboe Exchange, Inc. (the “Exchange” or “Cboe Options”) filed with the Securities and Exchange Commission (the “Commission”) the 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 purpose of this filing is to amend the Silexx Fees Schedule to introduce a waiver of Login ID fees for the first month for new users of any of the Silexx platforms and eliminate obsolete language.

                    The text of the proposed rule change is also available on the Exchange's website (                    *http://www.cboe.com/​AboutCBOE/​CBOELegalRegulatoryHome.aspx*), at the Exchange's Office of the Secretary, 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 this filing is to amend the Silexx Fees Schedule to introduce a waiver of Login ID fees for the first month for new users of any of the Silexx platforms and eliminate obsolete language.

                    By way of background, Silexx is an order entry and management trading platform for listed stocks and options that support both simple and complex orders.[3]                                          The platform is a software application that is installed locally on a user's desktop. It provides users with the capability to send option orders to U.S. options exchanges and stock orders to U.S. stock exchanges (and other trading centers), and allows users to input parameters to control the size, timing, and other variables of their trades. Silexx includes access to real-time options and stock market data, as well as access to certain historical data. The platform also provides users with the ability to maintain an electronic audit trail and provide detailed trade reporting. In addition, Silexx offers other functionality such as access to crossing orders tickets, equity order reports, and market data feeds (for specific fees). Use of Silexx is completely optional.                

#### Login IDs

                    Platform Login IDs may be purchased for different versions of the platform, including Basic, Pro, Sell-Side, Pro Plus                           ( print page 39805)                        Risk, and Buy-Side Manager. The Exchange now proposes to provide that Login ID fees are waived for the first month for any new user firm (                    *i.e.,*                     a firm that has never used any Silexx platform before).[4]                                          The proposed fee waivers apply during the calendar month in which Login IDs are first subscribed.[5] 

#### Clean Up Change

The Exchange recently introduced a two-month free-upgrade period for users that are currently on Silexx Basic. The upgrade allowed users of Silexx Basic to use the functionality of Silexx Pro for a period of two months (May 1, 2018 through June 30, 2018) at the current Silexx Basic rate of $200 per month per Login ID. After the two-month period ends, beginning July 1, 2018, the users were to be charged at the Silexx Pro rate of $400 per month until they choose to downgrade. As the free-upgrade period has since ended, the Exchange proposes to delete the obsolete language and eliminate the reference in the Silexx Fees Schedule

These proposed changes to the Silexx Fees Schedule are to take effect on August 1, 2018.

#### 2.  Statutory Basis 

                    The Exchange believes the proposed rule change is consistent with the Securities Exchange Act of 1934 (the “Act”) and the rules and regulations thereunder applicable to the Exchange and, in particular, the requirements of Section 6(b) of the Act.[6]                                          Specifically, the Exchange believes the proposed rule change is consistent with the Section 6(b)(5) [7]                                          requirements that the rules of an exchange be 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 regulating, clearing, settling, processing information with respect to, and facilitating transactions in securities, 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. Additionally, the Exchange believes the proposed rule change is consistent with Section 6(b)(4) of the Act,[8]                                          which requires that Exchange rules provide for the equitable allocation of reasonable dues, fees, and other charges among its Trading Permit Holders and other persons using its facilities.                

Particularly, the Exchange believes the proposed fee waiver provides for the equitable allocation of reasonable fees because the waiver of Platform Login ID fees for the first month will apply to all new users of new firms, regardless of which version of the platform they subscribe to. Additionally, the Exchange believes the proposed fee waiver is reasonable because new user firms will not have to pay those fees and because it serves as an incentive to market participants to start using the Silexx platform as an additional trading tool on their trading desks. The Exchange also notes that use of the platform is discretionary and not compulsory.

Lastly, the Exchange believes eliminating obsolete language maintains clarity in the Silexx Fees Schedule and alleviates potential confusion, thereby removing impediments to and perfecting the mechanism of a free and open market and a national market system, and, in general, protecting investors and the public interest.

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

Cboe Options 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 believes that the proposed rule change will not impose any burden on intramarket competition because the proposed rule change applies to all new user firms of Silexx. The Exchange notes that each version of Silexx is available to all market participants, and users have discretion to determine which version of the platform they register for based on functionality.

The Exchange does not believe that the proposed rule changes will impose any burden on intermarket competition that is not necessary or appropriate in furtherance of the purposes of the Act because the proposed change applies only to Cboe Options. To the extent that the proposed changes make Cboe Options a more attractive marketplace for market participants at other exchanges, such market participants are welcome to become Cboe Options market participants.

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

The Exchange neither solicited nor received comments on the proposed rule change.

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

                    The foregoing rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [9]                                          and paragraph (f) of Rule 19b-4 [10]                                          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 will institute proceedings to determine whether the proposed rule change should be approved or disapproved.
