MQL4 Expert Advisor Readiness Checks

Article MQL5 code base

Summary

This checklist identifies conditions to inspect when an MQL4 Expert Advisor is not ready to trade or needs a basic operational review. It covers whether a symbol is available in Market Watch, whether trading is permitted for the program and terminal, and whether the trade server allows transactions for the expert and the current account. It also includes server connection stability and account type.

The material is an operational checklist, not a trading strategy or a full troubleshooting procedure. It names checks but gives no steps for diagnosing failures, no code, and no evidence about effects on execution or performance. Its value is in reminding users that an Expert Advisor’s ability to trade depends on terminal, account, symbol, permission, and connectivity conditions as well as the program itself.

Key ideas

  • Confirm that the instrument is present in Market Watch.
  • Check trading permissions for both the Expert Advisor and the terminal.
  • Verify that the server permits trading for the expert and account.
  • Check connectivity and confirm the account type is suitable for the expert.
  • The checklist gives no detailed diagnosis steps or performance evidence.
