Reminder: FINRA Data Feed Test IP Addresses

July 2, 2018

Beginning Monday, July 9, 2018, FINRA will introduce dedicated test broadcast IP multicast channels for evening format testing for its data feeds—BTDS, ATDS, 144A, SPDS, SPDS-144A, TDDS 2.0 and BBDS, and will discontinue disseminating test data via the production data feed channels. The new channels are provisioned in the existing FINRA network for all approved direct data recipients. The test data stream will be supported via the “A (Primary)” and “B (Back-Up)” multicast groups. To receive streaming data via the new multicast groups direct data recipients should ensure their network providers have provided access.

The production BTDS, ATDS, 144A, SPDS, SPDS-144A, TDDS 2.0, and BBDS dissemination multicast groups will publish market data until each data feeds’ “End of Transmission” cut off. No further messages will be published over the production multicast groups after the cut off. Data feed recipients will receive application test data over the new test broadcast IP multicast groups during the weeknight testing period (normally between 9:05 p.m. and 10:30 p.m. ET). 

Questions regarding this notice should be directed to FINRA Product Management or call (866) 899-2107.
