Testing of FINRA Data Feed Test IP Addresses

May 15, 2018

As previously announced, 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. FINRA will discontinue disseminating test data via the production data feed channels when the dedicated test broadcast IP multicast channels are implemented.

Note: The production BTDS, ATDS, 144A, SPDS, SPDS-144A, TDDS 2.0 and BBDS dissemination multicast groups will continue to publish market data until each data feeds’ “End of Transmission” cutoff. After the End of Transmission cutoff, only Line Integrity messages (Category C - Type T) will continue to be disseminated. The Line Integrity messages will cease at approximately 9:15 p.m. ET.

IP Address Saturday Production Testing Details

Production User Acceptance Tests (UAT’s) will occur on Saturday, June 2, 2018, and Saturday, June 16, 2018. Transactions will be disseminated via the new test IP addresses only during the tests.

Data recipients should notify FINRA Market Operations of their intent to participate in the UATs via an email to FINRA Operations. Please include the firm name and names of testers no later than noon on the Thursdays prior to each test (May 31; June 14) in order to register for a test.

The UATs will start at approximately 9 a.m. ET and end at approximately 12 p.m. ET. The conference line listed below will be open for the duration of the tests. Due to a limited number of lines, firms should consider sharing the line if calling from the same location.
