### Cancel working orders for a contract and flatten its position. **Available to:** All authenticated users **Environments:** Demo, Live **[Rate Limit](/api/authentication#request-rate-limits-and-time-penalties):** No endpoint-specific limit Cancels the working orders for a specific `contractId` on the given `accountId` and closes (flattens) the resulting position with a market order. This is a request, not a guarantee — it can fail for reasons ranging from exchange rejection to misconfiguration. When the request is rejected, the response carries a `failureReason` and `failureText`. <Warning> Set `isAutomated` to `true` when this is triggered by code or an automated process, and `false` only when a human triggers it directly. </Warning> **Common Failure Scenarios** - The trading session is closed or the market has no quote (`SessionClosed`, `NoQuote`). - The market lacks the liquidity to close the position (`NotEnoughLiquidity`). - The user isn't permitted to trade this account or contract (`Unauthorized`). **Error Messages** | `failureReason` | Trigger | |-----------------|---------| | `SessionClosed` | The trading session is closed. | | `NotEnoughLiquidity` | The market can't absorb the closing order. | | `Unauthorized` | The user isn't permitted to trade this account or contract. | See the `failureReason` enum in the response schema for the complete list of values.
