Trading Technologies has scheduled a production update to Euronext RIC mappings following completion of user acceptance testing on 27 October. Release reference 219785 lists a 30 October production start and describes deployment over the weekend, with the aim of aligning the mappings with LSEG codes.[1]
The same entry says updated ICE_L codes are available in UAT, but leaves the production date to a later announcement. It does not support treating the Euronext and ICE_L changes as one completed live deployment. The table also leaves the production-completion field blank for this reference.[1]
A mapping change concerns identifiers
RICs identify instruments within the relevant data system. Updating a mapping concerns how an instrument is matched to its identifier; it does not, on its own, announce a new contract, change the contract’s economic terms or alter a broker’s customer charges.
For the release record, the concrete distinction is the deployment state: Euronext has a stated production window, while ICE_L remains a UAT update with production timing to follow. The note also mentions further market audits, which should be read as continuing work rather than proof that all exchange mappings have already been reviewed.[1]
