Update – August 5, 2023 TDDS Bandwidth Upgrade User Acceptance Test

Beginning Monday, August 14, 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).

TDDS 2.1 subscribers should 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).
