Allow Non-Displayed Intermarket Sweep Orders

The Exchange now permits an Intermarket Sweep Order (ISO) to be entered as a Non-Displayed Order (a "Non-Displayed ISO"). This change gives market participants and Users more flexibility to implement trading strategies across market centers.

ISO Price Availability By Trading Session

The Exchange will consider the limit price of an ISO available for new orders and for resting orders to re-price during Regular Trading Hours (9:30 a.m. to 4:00 p.m. Eastern Time). During the Early Trading Session (4:00 a.m. to 8:00 a.m. ET), Pre-Opening Session (8:00 a.m. to 9:30 a.m. ET), and Post-Closing Session (4:00 p.m. to 8:00 p.m. ET) the System will not consider an ISO's limit price available for new orders or re-pricing, except that an ISO entered during Regular Trading Hours that remains eligible for execution during the Post-Closing Session will remain available for new orders or re-pricing.

Multiple Re-Pricing For Non-Displayed Orders

Users may elect to have Non-Displayed Orders re-price multiple times each time the National Best Bid and Offer (NBBO) changes and receive a new timestamp, allowing the order to be ranked at more aggressive prices. A Non-Displayed Order will keep its original limit price regardless of the price at which it is ranked.
