###### Securities and Exchange Commission

          - [Release No. 34-63970; File No. SR-BYX-2011-004]

                    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 February 18, 2011, BATS Y-Exchange, Inc. (“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                           ( print page 12205)                        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 proposes to adopt new BYX Rule 11.21 to require Members to identify each order accurately as a Principal, Agency, or Riskless Principal Order.

## 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

The Exchange proposes to add new BYX Rule 11.21 for the purpose of increasing transparency and to enhance the surveillance database and audit trail of transaction data used by the Exchange in surveillance of its market. The proposed rule change would require Members to identify the capacity of each order accurately as a Principal, Agency, or Riskless Principal Order. For purposes of surveillance, the Exchange currently identifies the capacity of each order as Principal, Agency, or Riskless Principal; however, several other capacities are accepted upon order entry, including no response, which are thereafter mapped to one of the above-listed order capacities. By limiting the order capacity upon entry to Principal, Agency, or Riskless Principal and requiring Members to accurately submit an order capacity for each order, the Exchange will be able to more precisely identify the type of order received and more effectively surveil for abusive trading.

BYX does not have a rule that makes an explicit statement regarding a Member's obligation to input accurate information into the System. Notwithstanding, BYX believes that disciplinary cases against Members entering inaccurate or incomplete information may be brought appropriately under BYX Rule 3.1, which requires Members to observe high standards of commercial honor and just and equitable principles of trade. Rule 3.1 protects the investing public and the securities industry from dishonest practices that are unfair to investors or hinder the functioning of a free and open market, even though those practices may not be illegal or violate a specific rule or regulation. Because of the regulatory importance of accurate information input in the System, BYX believes a rule that directly addresses Members' obligation to provide accurate information is warranted. The proposed rule makes clear Members' obligation to input accurate information into the System and that failure to do so would be considered a violation of BYX Rules.

                    BYX notes that the Commission has previously approved rules proposed by the Nasdaq Stock Market LLC (“Nasdaq”) requiring participants to ensure that accurate information is entered into Nasdaq's system, including but not limited to the capacity of the participant.[5]                                          Thus, the proposed rule change would bring BYX Rules in line with those of other self-regulatory organizations.                

In order to allow Members sufficient time to review and complete any systems changes necessitated by this filing, the Exchange has proposed an operative date of April 4, 2011.

#### 2. Statutory Basis

                    The rule change proposed in this submission 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.[6]                                          Specifically, for the reasons described above, the proposed change is consistent with Section 6(b)(5) of the Act,[7]                                          because 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 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 to protect investors and the public interest. Specifically, the changes proposed herein will serve to promote the accuracy of information input into the Exchange. Accurate information is necessary for the efficient and fair operation of the Exchange, and will assist the Exchange in surveilling the markets for fraudulent activity.                

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

The Exchange does not believe that the proposed rule change imposes any burden on competition.

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

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

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

                    The foregoing rule change has become effective pursuant to Section 19(b)(3)(A) of the Act [8]                                          and Rule 19b-4(f)(6) [9]                                          thereunder because the proposal does not: (i) Significantly affect the protection of investors or the public interest; (ii) impose any significant burden on competition; and (iii) 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 if consistent with the protection of investors and the public interest.[10] 

                    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.[11] 

## IV. Solicitation of Comments

                    Interested persons are invited to submit written data, views, and arguments concerning the foregoing, including whether the proposed rule change is consistent with the Act.
