(a) Definition. The Nasdaq Kill Switch is an optional tool offered at no charge that enables Participants to establish pre-determined levels of risk exposure, to receive notifications as the value of executed orders, and if applicable, unexecuted orders approaches the risk levels, and to have order entry ports disabled and unexecuted orders administratively cancelled when the value of executed orders, and if applicable, unexecuted orders exceeds the risk levels set forth below. For purposes of this Rule, the term "Participant" has the meaning set forth in Equity 1, Section 1(a)(5).

(1) Gross Executed Risk Exposure. This refers to a pre-established maximum daily dollar amount for buy and sell orders across all symbols, where both buy and sell orders are counted as positive values. For purposes of calculating Gross Executed Risk Exposure, only executed orders are included.

(2) Gross Notional Risk Exposure. This refers to a pre-established maximum daily dollar amount for buy and sell orders across all symbols, where both buy and sell orders are counted as positive values. For purposes of calculating Gross Notional Risk Exposure, unexecuted orders on the Exchange book and executed orders are included.

(b) Establishing and Adjusting Levels. Participants or a Participant’s clearing member, as designated pursuant to paragraph (d), may set risk levels for each MPID individually. Each Participant, or a Participant’s clearing member, as designated pursuant to paragraph (d), is responsible for establishing and maintaining its risk levels. Participants or a Participant’s clearing member, as designated pursuant to paragraph (d), may set and adjust risk level values before the beginning of a trading day and during the trading day.

(c) Notification. Participants and a Participant’s clearing member, as designated pursuant to paragraph (d), will receive notifications when the total value of executed orders and, if applicable, unexecuted orders associated with an MPID exceeds 50, 75, 85, 90, and 95 percent of either of the risk level values. When either risk level value is exceeded, the notification will include the total number of orders cancelled and remaining open in the System.

(d) Clearing Member Designation. A Participant that does not self-clear may allocate the responsibility for establishing and adjusting the risk levels identified in paragraph (a) of this Rule to a clearing member that clears transactions on behalf of the Participant, if designated in a manner prescribed by the Exchange. A Participant that chooses to allocate responsibility to its clearing member may view any risk levels established by the clearing member pursuant to this Rule, and will be notified of any action taken by the Exchange with respect to its trading activity. By allocating responsibility to its clearing member, the Participant consents to the Exchange taking action with respect to the Participant’s trading activity as provided for in paragraph (e) of this Rule. A Participant may revoke responsibility allocated to its clearing member pursuant to this paragraph at any time, if designated in a manner prescribed by the Exchange.

(e) Breach Action and Reinstatement. Unless cancellation is prohibited by Rule 4752, 4753, or 4754, when a pre-established risk level is breached and the Kill Switch is triggered, it shall result in the immediate cancellation of all unexecuted orders of any type or duration entered by the Participant via the affected MPID, and in the immediate prevention of order entry of any type via the affected MPID. The Participant or the Participant’s clearing member, if designated pursuant to paragraph (d), must request reactivation of the MPID before trading will be reauthorized.

(a) Sharing Risk Settings. The Exchange may share any Participant risk settings in the trading system specified in Equity 6, Section 5 with the clearing member that clears transactions on behalf of the Participant. For purposes of this Rule, the term "Participant" has the meaning set forth in Equity 1, Section 1(a)(5).

(b) Clearing Member Designation. A Participant that does not self-clear may allocate the responsibility for establishing and adjusting the risk levels identified in Equity 6, Section 5 to a clearing member that clears transactions on behalf of the Participant, if designated in a manner prescribed by the Exchange. A Participant that chooses to allocate responsibility to its clearing member may view any risk levels established by the clearing member pursuant to this Rule, and will be notified of any action taken by the Exchange with respect to its trading activity. A Participant may revoke responsibility allocated to its clearing member pursuant to this paragraph at any time, if designated in a manner prescribed by the Exchange.

The Exchange offers certain risk settings applicable to a Participant's activities on the Exchange. The risk settings currently offered by the Exchange are:

(a) Share Size Control - When enabled by a Participant, this optional control will allow a Participant to limit the number of shares that the Participant may associate with an order placed on the Exchange;

(b) Order Type/Attribution Check - This control relates to the order types or modifiers that can be utilized (including pre-market, post-market, short sales, non-auction market orders and Intermarket Sweep Orders);

(c) Cancel-on-Disconnect Control - When enabled by a Participant, this optional control will allow a Participant, when it experiences a disruption in its connection to the Exchange, to immediately cancel all pending Exchange orders except for those designated for the Opening or Closing Crosses;

(d) The Nasdaq Kill Switch - This control is described in Equity 6, Section 3;

(e) Limit Order Protection - This control is described in Rule 4757(c);

(f) Price Collar Check - This control will automatically restrict a routed order from executing at a price that differs from the NBBO (at the time of order entry) by more than five percent or $0.25, whichever difference is greater. The system will proceed to route an order unless and until it crosses the greater of these two price collars, and if it does so, then the system will block further routings of the order that fall outside of the collars. For example, if the NBBO is $99 x $100 at the time of entry of a buy order, then the system will route the order at prices at or below $105, but will stop doing so if the offer price rises above $105 (five percent of the NBO).

(g) Maximum Order Volume Check - This control will automatically reject an order for routing away that exceeds a maximum volume of shares. As applied to equity orders, the default maximum order volume is set at 25,000 shares, but the Participant may request that the Exchange set a higher default based on historic volume.

(h) Maximum Single Order Notional Check – When enabled by a Participant this optional control will allow a Participant to limit the maximum dollar amount that the Participant may associate with an order placed on the Exchange;

(i) Cumulative Order Volume Check - This control will automatically block an attempt by a Participant using a particular MPID to route orders away to buy or sell equity securities that, cumulatively, exceed 9.5 million shares during a five second time period;

(j) Duplication Control - This control will automatically reject an order that a Participant submits to the Exchange to the extent that it is duplicative of another order that the Participant submitted to the Exchange during the immediately preceding period of time configurable for up to 30 seconds;

(k) Restricted Stock List - This control restricts the types of securities transacted (including restricted securities and hard to borrow securities);

(l) ADV Check - This control relates to the size of an order as compared to the consolidated average daily volume of the security (including the ability to specify the minimum value on which such control is based if the average daily volume of the securities is below such value);

(m) Fat Finger Protection - This control relates to the price of an order by evaluating whether the limit price is set too aggressively through the NBBO (percentage-based and dollar-based controls are available);

(n) Rate Thresholds Check - This control restricts the maximum number of messages that can be sent in a configurable rolling interval (including per port and per symbol);

(o) Market Impact Check - This control restricts an incoming order limit price from being priced through the far-side of the current LULD bands; and

(p) Gross Exposure Check - This control measures open, executed, or notional exposure; and, when breached, prevents submission of all new orders and, optionally, cancels all open orders.

The time of execution of the EVI Cross shall be extended for an additional 2 minutes if the Current Reference Price of the EVI Security changes by 1 percent or more in the final minute of a two-minute extension. The time of execution of the EVI Cross shall be extended no more than 30 times. If the time of execution of the EVI Cross has been extended 10 times, order cancellation will be prohibited.
