Contact Information:

As of 6/17/19 NFX will utilize a number of optional API fields to pass through additional trade information to OCC:

Executing Broker: For OTC Transactions NFX will start to publish the execution broker utilizing Tags 448 /452. There is a character limitation of 4 in this TAG. Any Broker MPID’s exceeding this value will be truncated and only include the first 4 characters.

Passive/Aggressive flags: NFX has recently modified its pricing schedule to incorporate a passive/active pricing model. Active executions in the CLOB (Central Limit Order Book) pay an execution fee of $0.50 per contract and passive executions will receive a $.40 rebate per contract. To help participants understand their execution costs the exchange will populate the custom OCC Tag “TrdCode” with the following values.

P : passive

A : active

Block transactions will not have this tag included as they are not considered active or passive.

For any questions or concerns please contact NFX or call 215.496.5409.
