Derivatives FIX Drop Copy Messages

The FIX Drop Copy session sends Execution Report (35=8) messages to the executing parties and client who might want a record of the trade.

Drop Copy Message Types

Customers can choose to receive Execution Reports over Drop Copy at two levels: Trade Execution and Order Status.

Trade Execution Reports

Trade (150=F): Complete and partial fills.
Trade Correction (150=G): Trade Correction on previously published fill.
Trade Cancel (150=H): Trade Bust message on previously published fill.

Order Status Reports

New/Canceled/Replaced Order (150=0/4/5): Confirms new, canceled, or replaced order:
- New Order (150=0): Confirms NewOrderSingle message.
- Canceled Order (150=4): Confirms OrderCancelRequest message or unsolicited cancel.
- Replaced Order (150=5): Confirms OrderCancel/ReplaceRequest message.
Rejected Order (150=8): Sent in case a new or cancel/replace order message is rejected.
Done for Day (150=3): Sent for all currently open orders after the trading day closes.
Expired Order (150=C): Sent for expired Day orders.

Admin Message Types

EventResendRequest (35=F3): Client request to resend order events in a specified range.
EventResendComplete (35=F4): System response to successful F3 request.
EventResendReject (35=F5): System response to unsuccessful F3 request.

Parties Repeating Group (453)

Tag	Name	FIX Type	Req	Description
453	NoPartyIDs	NumInGroup	Y	Number of PartyIDs in repeating group: `453=5` for all order-status, trade, and drop copy messages.
→ 448	PartyID	String(20)	Y	Party identifier/code
→ 447	PartyIDSource	Char	Y	`447 = D (Proprietary)`
→ 452	PartyRole	Int	Y	1 - Subfirm Code 4 - Clearing Firm Code 11 - Order Originating Trader 55 - Session ID 3 - Client ID (ITM name used for the order)

The new PartyRole=3 (Client ID) entry carries the name of the ITM (clearing account) that the order actually used. When firm/ITM overrides are enabled on Order Entry, this value reflects the overridden ITM; otherwise it matches the user’s default ITM.

Block Trades

Block trade events are disseminated over Drop Copy to the firm’s subscribed sessions (for firms enabled for block trades). Block trades are reported using the same Execution Report (35=8) messages as regular trades, identified with TrdType = 1 (828=1):

Event	Message
New block trade	Trade (150=F) execution report (`ExecType = F`).
Block trade amended	Trade Correction (150=G). `ExecRefID` (19) references the `ExecID` of the original execution report.
Block trade busted / cancelled	Trade Cancel (150=H). `ExecRefID` (19) references the `ExecID` of the original execution report, allowing firms to remove the trade from their records.
