Hello @AniK

Do you mean this PCN206364-RFA7.x and SFC legacy APIs and Legacy Protocol Converter – end of support, impacting RTDS, RTMDS, LPC, Full-Tick Edge Devices and legacy Real-Time APIs notification?

If so, it means

* The Real-Time APIs that depend on Marketfeed and SSL will stop working when Marketfeed and SSL are removed from the Real-Time infrastructure. The suggestion is to migrate to the strategic Real-Time APIs.
* The RFA 7.x with RSSL/OMM will continue working, but the RFA 7.x is end of life and no longer supported. The suggestion is to migrate to RFA 8.x

Please check the Choosing a Real-time Streaming API article about the migration.

Yes, the APIs still work when connecting to the servers (RTDS, RTMDS) that support the legacy SSL protocol. However, the servers must be configured to support the SSL protocol.

Please check when those servers will remove the support of SSL.

We will also remove Marketfeed and SSL from:

All versions of RTDS from Q4 2028 onwards

RTMDS from Q2 2027 onwards

Full Tick Edge devices from March 2026 (end of Q1 2026) onwards
