TDDS 2.1 Bandwidth Modification

Beginning Monday, July 24, 2023, FINRA will increase the bandwidth rate for the Trade Data Dissemination Service 2.1 (TDDS 2.1) vendor feed from 2,500 kilobits per second (Kbps) to 3,000 kilobits per second (Kbps). FINRA will offer testing for the new bandwidth rate and will announce details for the test as the date approaches.

TDDS 2.1 subscribers are encouraged to plan to ensure their systems can accept the higher data rates. The TDDS 2.1 data rate change does not impact any of the ORF reporting applications (FIX and TRAQS).
