MT5 order rejected? Find the exact cause.

Send the retcode, the request values and the nearby Journal lines. I will trace one failure against the symbol, account and broker rules, then give you a written cause map and the smallest safe next step.

Written evidence map

24-hour diagnostic

No account access

One rejected order, modification, stop-loss or take-profit incident
Retcode and Journal evidence mapped to the exact request
Volume, price step, stops level, order mode and filling mode checked
Broker constraints separated from code defects
Written reproduction steps and a fixed repair quote if a code change is needed

When the evidence is complete

I reproduce or reconcile the incident, identify the first proven cause and deliver the report within 24 hours of receiving the required evidence.

When evidence is missing

I tell you exactly what is missing before payment. The free scope check does not turn into an open-ended investigation.

When it is not a code defect

You still receive the broker or environment boundary and a reproducible next step. A repair is quoted only when a code change is actually supported by the evidence.
