MT5 Order Rejection and Retcode Diagnostic

Reconcile one rejected or misconfigured MT5 market, pending, stop-loss or take-profit request against the symbol, account-mode and broker rules visible at the incident, then receive a written evidence map and bounded repair plan.

What is included

  • One failed order, modification or protective-stop incident traced end to end
  • Trade retcode and nearby Experts or Journal lines mapped to the request
  • Volume, tick-size, stops-level, order-mode and filling-mode validation
  • Broker, symbol and account-mode assumptions separated from code defects
  • Reproduction checklist and fixed-scope repair estimate

What I need from you

  • Exact symbol, action, timestamp, terminal build and account mode
  • Relevant Experts and Journal lines with identity and credentials removed
  • Requested volume, price, stop loss and take profit values
  • Editable source for the affected request flow if you own or may share it

Scope boundaries

  • One incident and one affected order flow are included
  • No login, remote terminal access, API key or account credential is requested
  • A passing preflight cannot guarantee later server acceptance, fill price or trading results
