Client supplied identifiers

Tag	Name	Defined In	Echoed Back	Description
11	ClOrdID	New Order Single `<D>` Order Cancel Request `<F>`	Execution Report `<8>` Order Cancel Reject `<9>`	The client's request identifier, which may refer to either an order or an order-cancel request. Gemini strongly recommends making this field unique among active orders for a given port. One common practice is to include a date prefix (e.g., `20160114_0001`). Gemini does not enforce uniqueness, so sending a duplicate ClOrdID `<11>` might cause confusion in downstream reports.
41	OrigClOrdID	New Order Single `<D>` Order Cancel Request `<F>`	Execution Report `<8>` Order Cancel Reject `<9>`	Specifies the ClOrdID `<11>` of the order you want to cancel. This must correspond to a currently outstanding order submitted during this trading session. Gemini will cancel every active order whose ClOrdID `<11>` matches the value in this field.
