Use case

The wallet/marketcancelorder method is used for:
  • Canceling orders that are no longer needed or desired.
  • Withdrawing funds locked in unfilled orders back to the account balance.
  • Adjusting trading strategies by removing stale or mispriced orders.
  • Managing order book exposure and market position.
  • Implementing automated order management systems.
You can only cancel orders that you created and that are still active. Once an order is fully filled or already canceled, it cannot be canceled again. The locked tokens will be returned to your account balance upon successful cancellation.
