TDDS 2.0 Bandwidth Modification

June 13, 2018

Beginning Monday, October 22, 2018, FINRA will increase the bandwidth rate for the Trade Data Dissemination Service 2.0 (TDDS 2.0) vendor feed from 800 kilobits per second (kbps) to 2,500 kilobits per second (kbps).


FINRA will test the new bandwidth rate on Saturday, September 22, 2018, and on Saturday October 6, 2018. The TDDS 2.0 production IP addresses and ports will publish the test data. 

TDDS 2.0 subscribers are encouraged to participate in at least one of the tests in order to ensure their systems can accept the higher data rates. TDDS 2.0 subscribers participating in any of the tests should ensure their network provider is successfully processing the feed during the test. FINRA will issue additional test details as the dates approach.

Note: The TDDS 2.0 data rate change and testing opportunity does not impact any of the ORF reporting applications (CTCI, FIX and TRAQS) and there is no requirement for firms to submit trade reports for the test.
