MQL4 and MQL5 Bug Fix or Modification
A bounded repair or modification for an Expert Advisor, indicator or script when you can provide editable source and a reproducible expected result.
What is included
- Compile, runtime and affected-flow diagnosis
- One agreed bug fix or clearly bounded feature
- Experts and Journal log review when supplied
- Corrected editable source and compiled build
- Concise change summary and verification steps
What I need from you
- Editable MQ4/MQ5 source and required includes
- Current behaviour and expected behaviour
- Exact reproduction steps, symbol and timeframe
- Relevant logs, screenshots and terminal build
Scope boundaries
- No EX4/EX5 decompilation or protected-code extraction
- A revision covers the agreed issue, not unrelated features
- Performance changes are measured, never promised
