BackgroundTo provide a normalised view of the ExecutionReport received by Clients, changes are being made to the quantity fields listed below. Currently these values are taken directly from the Venue messages. For the venues where these values are not as per Whisperer standard, improvements are being made to bring them inline with the schema definition. Field | Schema definition | Normalisation Issue | Affected Venues | Release Version |
|---|
| LegCumQty | Total quantity filled so far on this Leg of the Order. | LegCumQty is populated inconsistently by some venues across different OrderStatuses. | autobahnfx_rapid, baml, barx, citi_colo, rbc_trading, standardchartered_s2bx, statestreet_efx, t360_tex. | 2025.11.19.WE.RHEL9 - bnpparibas_efx_algo, fxspotstream_algo, precision_algo, ubs_algo, autobahnfx_rapid, baml, bgc_midfx, broadridge_orders, bnpparibas_efx_streaming 2025.12.03.WE.RHEL9 - All venues except lseg_ftg, refinitiv_mapi, barx, jpmorgan_fx_algo 2025.12.04.WE.RHEL9 - All venues | | LegLeavesQty | Quantity remaining to execute on this Leg of the Order. | LegLeavesQty is populated inconsistently by all venues across different OrderStatuses. | All taker APIs | 2025.11.19.WE.RHEL9 - bnpparibas_efx_algo, fxspotstream_algo, precision_algo, ubs_algo, autobahnfx_rapid, baml, bgc_midfx, broadridge_orders, bnpparibas_efx_streaming 2025.12.03.WE.RHEL9 - All venues except lseg_ftg, refinitiv_mapi, barx, jpmorgan_fx_algo 2025.12.04.WE.RHEL9 - All venues | | LegAllocQty | If ExecType=Calculated/Trade then ABS (SUM (LegAllocQty))=LegLastQty, otherwise ABS (SUM (LegAllocQty))=LegOrderQty | LegAllocQty is is populated inconsistently across different ExecTypes.

ChangeThis change will ensure that the above quantity fields are normalised consistently across all venues OrdStatus/ExecType combinations. These fields will never be null in the ExecutionReport. Timeline- Phased rollout starting August 2025.
