Modifications

ModificationAccepted dataclass

Bases: ResponseBase

Event indicating that the requested modification has been acknowledged by the brokers and that the updated order parameters are active at the execution venue.

Field Type Semantics
ts_event_ns int Time at which the acceptance was observed by the system, as UTC epoch nanoseconds.
ts_created_ns int Time at which the event object was created, as UTC epoch nanoseconds.
ts_broker_ns int Time reported by the brokers for the modification acceptance, as UTC epoch nanoseconds.
associated_order_id uuid.UUID Identifier of the modified order.
broker_order_id str or None Broker-assigned identifier of the order after modification, if reported.
