###### Securities and Exchange Commission

          - [Release No. 34-81368; File No. SR-BatsBYX-2017-18]

                    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 August 8, 2017, Bats BYX Exchange, Inc. (the “Exchange” or “BYX”) 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 Exchange has designated this proposal as a “non-controversial” proposed rule change pursuant to Section 19(b)(3)(A) of the Act [3]                                          and Rule 19b-4(f)(6)(iii) thereunder,[4]                                          which renders it effective upon filing with the Commission. 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 filed a proposal to extend the pilot period for the Exchange's Retail Price Improvement (“RPI”) Program (the “Program”), which was set to expire on July 31, 2017, for 12 months, to expire on July 31, 2018.

                    The text of the proposed rule change is available at the Exchange's Web site at                     *www.bats.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 parts of such statements.

### A. Self-Regulatory Organization's Statement of the Purpose of, and Statutory Basis for, the Proposed Rule Change

#### 1. Purpose

                    In November 2012, the Commission approved the RPI Program on a pilot basis.[5]                                          The Program is designed to attract retail order flow to the Exchange, and allows such order flow to receive potential price improvement. The Program is currently limited to trades occurring at prices equal to or greater than $1.00 per share. Under the Program, all Exchange Users [6]                                          are permitted to provide potential price improvement for Retail Orders [7]                                          in the form of non-displayed interest that is better than the national best bid that is a Protected Quotation (“Protected NBB”) or the national best offer that is a Protected Quotation (“Protected NBO”, and together with the Protected NBB, the “Protected NBBO”).[8] 

                    The Program was approved by the Commission on a pilot basis running one-year from the date of implementation.[9]                                          The Commission approved the Program on November 27, 2012.[10]                                          The Exchange implemented the Program on January 11, 2013, and has extended the pilot period four times.[11]                                          The pilot period for the Program expired on July 31, 2017. The lapse of the pilot was inadvertent and this filing seeks to reinstate the pilot under the same terms as the original pilot.                

#### Proposal To Extend the Operation of the Program

                    The Exchange established the RPI Program in an attempt to attract retail order flow to the Exchange by potentially providing price improvement to such order flow. The Exchange believes that the Program promotes competition for retail order flow by allowing Exchange members to submit Retail Price Improvement Orders (“RPI Orders”) [12]                                          to interact with Retail Orders. Such competition has the ability                           ( print page 38961)                        to promote efficiency by facilitating the price discovery process and generating additional investor interest in trading securities, thereby promoting capital formation. The Exchange believes that extending the pilot is appropriate because it will allow the Exchange and the Commission additional time to gather and analyze data regarding the Program that the Exchange has committed to provide.[13]                                          As such, the Exchange believes that it is appropriate to extend the current operation of the Program.[14]                                          Through this filing, the Exchange seeks to extend the current pilot period of the Program until July 31, 2018.                

#### 2. Statutory Basis

                    The Exchange believes that its proposal is consistent with the requirements of the Act and the rules and regulations thereunder that are applicable to a national securities exchange, and, in particular, with the requirements of Section 6(b) of the Act.[15]                                          In particular, the Exchange believes the proposed change furthers the objectives of Section 6(b)(5) of the Act,[16]                                          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, and to remove impediments to and perfect the mechanism of a free and open market and a national market system. The Exchange believes that extending the pilot period for the RPI Program is consistent with these principles because the Program is reasonably designed to attract retail order flow to the exchange environment, while helping to ensure that retail investors benefit from the better price that liquidity providers are willing to give their orders. Additionally, as previously stated, the competition promoted by the Program may facilitate the price discovery process and potentially generate additional investor interest in trading securities. The extension of the pilot period will allow the Commission and the Exchange to continue to monitor the Program for its potential effects on public price discovery, and on the broader market structure.                

### 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 proposed rule change extends an established pilot program for 12 months, thus allowing the RPI Program to enhance competition for retail order flow and contribute to the public price discovery process.

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

The Exchange has not solicited, and does not intend to solicit, comments on this proposed rule change. The Exchange has not received any written comments from Members or other interested parties.

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

                    Because the foregoing proposed rule change does not: (A) Significantly affect the protection of investors or the public interest; (B) impose any significant burden on competition; and (C) by its terms, 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 [17]                                          and paragraph (f)(6) of Rule 19b-4 thereunder,[18]                                          the Exchange has designated this rule filing as non-controversial.                

                    The Exchange has requested the Commission waive the standard five-day pre-filing and 30-day operative delay requirements as specified in Rule 19b-4(f)(6)(iii) [19]                                          so that BatsBYX's RPI Program can continue to operate with limited interruption. The Commission waives the 5-day pre-filing requirement. In addition, the Commission believes that waiving the 30-day operative delay is consistent with the protection of investors and the public interest because it will allow the Exchange to reinstate the RPI Program on a pilot basis immediately. For these reasons, the Commission designates the proposal to be effective and operative upon filing with the Commission.[20]

The terms Protected NBB and Protected NBO are defined in BYX Rule 1.5(s). The Protected NBB is the best-priced protected bid and the Protected NBO is the best-priced protected offer. Generally, the Protected NBB and Protected NBO and the national best bid (“NBB”) and national best offer (“NBO”, together with the NBB, the “NBBO”) will be the same. However, a market center is not required to route to the NBB or NBO if that market center is subject to an exception under Regulation NMS Rule 611(b)(1) or if such NBB or NBO is otherwise not available for an automatic execution. In such case, the Protected NBB or Protected NBO would be the best-priced protected bid or offer to which a market center must route interest pursuant to Regulation NMS Rule 611.
