Parameters from the server's own tool schema.
Cancelling an open order is an irreversible action — once cancelled, the order cannot be reinstated. This removes an active trading order from the market, which could have significant financial consequences if misused (e.g., cancelling legitimate orders at critical market moments). It falls under Destructive as the cancellation cannot be undone, and is rated high severity due to its direct impact on trading activity.
