To accommodate the early closing schedule, the UTP SIP will adjust the closing transmission schedules for its data services. For the modified closing times on December 24, 2025 please refer to the UTP SIP Transmission Schedule on the UTP Plan website for a detailed listing of early close message timing.

Please note that all trade transactions reported after 1:00 p.m., ET, should be marked with an appropriate extended-hours sale condition modifier on UTP early close dates.

Can test data be disseminated on the market holidays?

Yes, as announced in UTP Vendor Alert 2017-14, the UTP SIP introduced new “Test Broadcast” IP Multicast Channels dedicated to evening format and content testing. While this change is designed to minimize the possibility of data recipients processing test data as production data, during non-market hours the UTP SIP may broadcast unmarked test data. Data recipients should continue to take necessary precautions to protect their systems against database corruption during evenings, weekends, early close and market holidays.
