        The endpoint closes an open [collateral](/glossary#balance-collateral)
        position at the current market price. The system places a market order
        in the opposite direction to fully close the specified position. Any
        attached take-profit or stop-loss orders are cancelled automatically.

        <Accordion title="Error Codes">
          - `30` - default validation error code (for example, a missing or malformed `positionId` or `market`)
          - `104` - position not found. Returned whether the `positionId` does not exist, the position is already closed, or it is not owned by the account — these cases are not distinguished
          - `10` - insufficient balance to fund the closing market order
