Stops an Order Strategy that is already running, identified by its orderStrategyId, and cancels its remaining working orders. Order strategies are the multi-bracket constructs created with startOrderStrategy. Use this endpoint to terminate the whole strategy; to change a strategy's parameters while keeping it running, use modifyOrderStrategy instead.

The request body requires only orderStrategyId. Interrupting a strategy stops the strategy logic and cancels its open orders, but it does not flatten any position the strategy has already opened — close that separately with liquidatePosition if needed.

As with other order commands, success is not guaranteed — the strategy may already have completed or its orders may already have filled. The endpoint returns an OrderStrategyStatusResponse. When the request is rejected, the response carries a failureReason and an errorText describing the problem; on success the response includes the updated orderStrategy.

Common Failure Scenarios

• The strategy already completed or was interrupted (TooLate).
• Another command for the strategy is still being processed (AnotherCommandPending).
• The user isn't permitted to trade this account (Unauthorized).

Error Messages

See the failureReason enum in the OrderStrategyStatusResponse schema for the complete list of values.
