Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (the “Act”), and Rule 19b-4 thereunder, notice is hereby given that on October 28,2015, EDGX Exchange, Inc. (the “Exchange” or “EDGX”) 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 and Rule 19b-4(f)(6)(iii) thereunder, 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 the Substance of the Proposed Rule Change

The Exchange filed a proposal to amend Rules 21.2, 21.6, and 21.7 to change the time orders will be accepted on the Exchange's options platform (“EDGX Options”) from 8:00 a.m. to 7:30 a.m.

The text of the proposed rule change is available at the Exchange's Web site at www.batstrading.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

The Exchange is proposing to amend Rules 21.2, 21.6, and 21.7 to change the time orders will be accepted on EDGX Options from 8:00 a.m. to 7:30 a.m. Currently, Exchange rules state that the Exchange will begin accepting orders at 8:00 a.m. Eastern Time. Orders would then be available for execution as of 9:30 a.m. until 4:00 p.m. Eastern Time. The Exchange does not propose to amend how it would handle orders accepted prior to the market open other than to begin accepting orders at 7:30 a.m. Eastern Time rather than 8:00 a.m. Eastern Time.

First, the Exchange proposes to amend Rule 21.2(a) to state that the Exchange will begin accepting orders at 7:30 a.m. Eastern Time, as described in Rule 21.7 and discussed below. Second, the Exchange proposes to amend Rule 21.6(c) to state that orders can be entered into the System starting at 7:30 a.m. Eastern Time. Currently, the Rule 21.6(c) states that orders can be entered into the System from 8:00 a.m. Eastern Time until the market close. While orders will be accepted by the System starting at 7:30 a.m. Eastern Time, they will not be eligible for execution until 9:30 a.m. Eastern Time.

Lastly, as amended, Rule 21.7 would state that the Exchange will accept market and limit orders and quotes for inclusion in the opening process beginning at 7:30 a.m. Eastern Time, rather than 8:00 a.m. as is currently the case and will continue to accept market and limit orders and quotes until such time as the Opening Process is initiated in that option series (the “Order Entry Period”), other than index options. The Exchange will continue to not accept IOC or FOK orders for queuing prior to the completion of the Opening Process. The Exchange will also continue to convert all Intermarket Sweep Orders (“ISOs”) entered for queuing prior to the completion of the Opening Process into non-ISOs.

2. Statutory Basis

The Exchange believes that its proposal to begin accepting orders at 7:30 a.m. 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. In particular, the proposal is consistent with Section 6(b)(5) of the Act because it is designed to promote just and equitable principles of trade and to remove impediments to and perfect the mechanism of a free and open market and a national market system. The Exchange believes that accepting orders at 7:30 a.m. will benefit investors, the national market system, Members, and the Exchange market by increasing competition for order flow and executions, and thereby spurring product enhancements and lowering prices. The Exchange also notes that other options exchanges currently accept orders prior to 8:00 a.m. Eastern Time and the proposal would enable the Exchange to directly compete with these exchanges for order flow.

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. To the contrary, the proposed rule change is a competitive change that is designed to attract additional order flow to the Exchange. The proposed rule change would, therefore, increase competition by enabling the Exchange to accept orders starting at 7:30 a.m. Eastern Time like its competitors. For all the reasons stated above, the Exchange does not believe that the proposed rule changes will impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act, and believes the proposed change will enhance 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. 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 and paragraph (f)(6) of Rule 19b-4 thereunder, the Exchange has designated this rule filing as non-controversial. The Exchange has given the Commission written notice of its intent to file the proposed rule change, along with a brief description and text of the proposed rule change at least five business days prior to the date of filing of the proposed rule change, or such shorter time as designated by the Commission.

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: (1) Necessary or appropriate in the public interest; (2) for the protection of investors; or (3) 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.
