Firm and ITM overrides

Contact Coinbase Derivatives Exchange (CDE) Support to enable the firm/ITM override feature for a FIX session.

This feature is optional and only open to FCM.
Overrides apply only to NewOrderSingle; cancel, cancel/replace, and other messages must omit these Parties rows.
Each override request must include exactly two party rows in the Parties (453) group:
1. 452=1 (Executing Firm) with 447=99 and 448=<sub-firm code>
2. 452=3 (Client ID) with 447=99 and 448=<ITM name>
The supplied firm and ITM must reside under the same FCM as the trading user; cross-FCM overrides are rejected.
Both rows are mandatory; an incomplete pair, unknown identifiers, or an alternate PartyIDSource results in rejection.
SelfMatch Prevention fields (7928 ID and 8000 mode) follow the normal SMP configuration for the session
If the firm/ITM override feature is disabled for the FIX session, any order containing the override Parties group is rejected, and the system does not fall back to the user’s default firm/ITM.

Example override block (placed after the standard 35=D fields):

453=2|448=SUBFIRM123|447=99|452=1|448=ITM-ABC|447=99|452=3

OCO Orders

OCO (One Cancels the Other) orders combine the features of limit and stop orders (and CDE treats them as a single order, not two linked ones). OCO orders let users set predefined limit and stop levels simultaneously depending on their view of the market. Initially, an OCO order acts like a regular limit order, contributing to market data. When its stop price condition is met, it shifts and behaves like a stop limit order. Price Rules

Sell OCO: Limit Price must be > StopPx
Buy OCO: Limit Price must be < StopPx

Caveats

DAY, GTC and GTD are supported for TimeInForce
The Post-Only tag is not supported. It cannot be populated or must be false.
