Closing All Open Trading Positions with Error Handling

Article MQL5 code base

Summary

The document describes a trading-platform button that closes all open positions across instruments in one action. It focuses on the control logic used when an order cannot be closed: the revised approach checks the platform’s last error and stops processing for selected error codes, while retrying other failures. This is intended to avoid an infinite loop without abandoning the effort to close remaining trades.

The material is a brief implementation note rather than a trading strategy. It provides a code excerpt but no tests, operational results, explanation of the error codes, or discussion of partial-close behavior. Its usefulness is therefore limited to the general execution lesson that retry loops need explicit handling for terminal errors; the actual behavior depends on the platform and the surrounding order-processing logic.

Key ideas

  • A single action can be used to close open positions across trading pairs.
  • The revised logic checks the last error when a close operation fails.
  • Selected error codes stop further attempts, while other errors trigger another attempt.
  • The note gives no test results or detail about the platform-specific meaning of each error code.
