REMINDER: Cboe Europe Equities: Trade Reports - Mandatory change to TradeID field, effective Mon 27th April

February 11, 2020 13:53:59

Dear Cboe Europe Equities Participants

Currently, the first three of twelve characters in the TradeID field (FIX tag 1003) supplied on Trade Capture Report messages (ETRs and TCRs) in BXE, CXE, DXE and the TRF environments are always set to "000". Effective Monday 27th April 2020, Cboe Europe Equities (Cboe) will begin to utilise all twelve characters in the TradeID field across the aforementioned production environments. Any participants who currently have their system configured to remove the three leading zeros should be aware that these will be utilised as part of the TradeID upon the effective date and review accordingly.

Furthermore, effective Monday 27th April 2020, the FIX tags and file columns described in the below table which are also used to convey a TradeID will be extended to always include these additional three characters across the aforementioned environments, as currently these are always stripped off.

Rationale for change
These changes will allow the Cboe systems to utilise all twelve characters of the TradeID on Trade Capture Report messages in preparation for a change to introduce unique identifiers over a period of one year, with the goal of allowing Participants to specify only this ID when amending or cancelling trade reports at a date to be announced in the future.

Impact
This change will impact the following FIX Tags as this extended value will also be used on the messages to the Central Counterparties (CCPs):
