ADF Documentation

FINRA supports connectivity to the ADF platform using FIX 4.4 protocol messaging. The following specifications detail the inbound and outbound message layouts for trade reporting, quoting and order response reporting to the ADF system.

FINRA ADF Reference Data is supplied via the Web API Specification for the Equity Trade Reporting Facility.

Please note: As of 10/24/16, the Auto-Lock functionality on clearing-eligible trades submitted for Trade Acceptance, as described in Rule 7140(a)(2) and (a)(3), will be disabled until further notice. If an alleged contra party takes no action on a clearing-eligible trade submitted for Trade Acceptance, the trade will be carried over and remain open, and will NOT be automatically locked-in and sent to NSCC for clearing at 2:30 p.m. ET on T+1. FINRA will determine at a future date when to make this functionality available and will make an announcement to that effect.

For any technology questions regarding the ADF platform, please contact Product Management at (866) 899-2107 or email FINRA Product Management.
