Interrupt Order Strategy

### Stop a running Order Strategy. **Available to:** All authenticated users **Environments:** Demo, Live **[Rate Limit](/api/authentication#request-rate-limits-and-time-penalties):** 500 requests per hour, 2-second back-off, counts all requests 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`](/api/rest-api-endpoints/orders/start-order-strategy). Use this endpoint to terminate the whole strategy; to change a strategy's parameters while keeping it running, use [`modifyOrderStrategy`](/api/rest-api-endpoints/orders/modify-order-strategy) 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`](/api/rest-api-endpoints/orders/liquidate-position) 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** | `failureReason` | Trigger | |-----------------|---------| | `TooLate` | The strategy already completed or was interrupted. | | `AnotherCommandPending` | A previous command for this strategy hasn't completed. | | `Unauthorized` | The user isn't permitted to trade this account. | See the `failureReason` enum in the `OrderStrategyStatusResponse` schema for the complete list of values.
