Comprehensive risk management features are built into Nasdaq’s trading technology and include the following protections on NOM.
Order Price Protection (OPP): Checks the limit price of an incoming order against the NBBO and BBO and rejects the order if the limit crosses a certain parameters.
Acceptable Quote Range: Protects orders and quotes from executing at levels too far away from an initial quote execution price.
Market Access Protection: Guards against duplicate orders as well as validates orders with cumulative volume checks.
Kill Switch: Provides participants with a GUI that enables them to request quote removals and/or order cancellations.
Rapid Fire: Removes NOM Market Maker SQF quotes and/or QUO (previously OTTO 1.4d) orders from the marketplace when certain pre-set percentage or volume thresholds are met.
Multi-Trigger Rapid Fire: Removes NOM Market Maker SQF quotes and QUO (previously OTTO 1.4d) orders in an option series in all underlying issues when a specified number of Rapid Fire events occur over a chosen interval.
Anti-Internalization or AIQ: Prevents NOM Market Makers from trading against their own quote and order interest. Resting interest will be cancelled when an incoming quote or order entered on the opposite side of the market from the same market making firm.
Cancel on Disconnect (FIX, OTTO, QUO (previously OTTO 1.4d) and SQF Connections): A loss of communication will automatically cancel all orders and open quotes on the affected port. Quotes will be cancelled across all client applications that are associated with the same market maker ID and underlying issues.
Through our primary data center, firms can access all eleven of Nasdaq's U.S. Markets via Direct Connection or Co-Location. Nasdaq also offers customers the ability to connect to our markets from key financial data centers outside our Carteret facility through our Point of Presence Service.
Specialized Quote Interface (SQF): Market makers provide liquidity using SQF, which allows market makers to supply up to 200 quotes in one message.
Financial Information eXchange (FIX): A vendor-neutral standard message protocol used for submitting orders to NOM.
Quote Using Orders (QUO): This proprietary protocol allows market maker participants to efficiently enter options orders into the NOM market and receive executions from Nasdaq. Orders are treated as quotes and count toward quoting obligations over QUO.
Clearing Trade Interface (CTI): The Options Clearing Trade Interface is a product that disseminates clearing trades, trade corrections, trade cancels and optional administrative messages.
Gain direct access to the full options data feed suite via multiple exchange venues—based on time, complexity, and uniformity.
