Question 2.1.3 Data Field (3)

If an OMP produces an ACER XML file, but instead of loading the data through an RRM, the ACER XML file is provided to the market participant to load into their RRM of choice - will the validation of the Field 3 (Trader ID) data be based upon the OMP Trader Id (3a) or the Participant Trader Id (3b)?

OR

If an OMP produces an ACER XML file, but instead of loading the data through an RRM, the ACER XML file is provided to the market participant to load into their ETRM system and then report the trade to their RRM of choice - will the validation of the Field 3 (Trader ID) data be based upon the OMP Trader Id (3a) or the Participant Trader Id (3b)?

"traderIdForOrganisedMarket" (Field No. 3a)

"traderIdForMarketParticipant" (Field No. 3b)

• MP A trades on OMP 1.
• OMP 1 uses RRM 1.
• MP A opts out of OMP 1 reporting, and requests the ACER XL data to lodge with their RRM of choice (RRM 2).
• OMP 1 generates a daily ACER XML file for MP A.
• MP A takes the file and loads it to RRM 2.

In this instance, does the ACER check on Field 3 (Trader Id) look at the OMP value (3a) as the data was sourced from an OMP or the participant value (3b as the data was loaded via a participant?

Suggest that in this instance, either value be allowed for reporting.

Answer

Because the trade is executed at the Organised Market Place, the market participant should report the trade/order report with the same information of the Organised Market Place and therefore “traderIdForOrganisedMarket" (Field No. 3a) should be reported.
