09/22/2025 | Improvements | FIX Services | LSEG: Eurex - RIC rename for 2 digit year code
On October 6th of this year, Refinitiv (LSEG) will rename Eurex RICs representing Futures and Spread contracts both on Real-time and Reference Data Products to support two-digit year codes. Underlying Futures contracts for Options on Futures will be displayed with a 2 digit year code. This change will also be applicable for Market by Price data, Level 2 RICs and delayed data.
TT will deploy the required changes to Production before the Refinitiv planned changes in production. These changes are now available for testing in UAT.
All currently deployed versions of TT FIX services are compatible with this change. TT customers using RICs for FIX Order Routing, Drop Copy or Market Data are encouraged to test their FIX applications in UAT prior to go-live. (Ref 189790) Production Release: 10/03/2025 Version: v291 |
09/17/2025 | Improvements | FIX Services | Added a new enum value, X', Series Key, to SecurityAltIDSource (tag 456) for Security Definition messages. When present, the associated SecurityAltId (455) will contain the value of the PDS Series Key field for the current instrument.
The new enum is supported for Security Definition messages only (not in SecurityAltId group for other message types), and only when tag 58 on the SecurityDefinitionRequest(c) contains 456=X. (Ref 188542) Version: v291 |
