I will debug, optimize, and back test your mql5 expert advisor on meta trader 5
About this Gig
Is your EA producing wrong entries, errors, or blowing accounts in live trading?
I will diagnose, fix, and improve your existing MQL5 Expert Advisor. As a real trader with 10+ years on MT5, I understand both the code and the market logic behind it meaning I catch errors that pure programmers often miss.
What I fix and improve:
Compilation errors and runtime crashes
Wrong lot sizing or risk calculation bugs
Incorrect candle indexing (the #1 backtesting mistake)
SL/TP not triggering correctly
Orders not opening or closing as expected
Backtest vs. live discrepancies
Adding missing features: trailing stops, breakeven, filters
Performance optimization: reducing CPU load, fixing memory leaks
Deliverables:
Fixed/optimized .mq5 source + .ex5 compiled file
Written summary of all changes made
Backtest comparison: before vs. after (where applicable)
Send me your .mq5 file and describe the problem. I will review it and confirm scope before you order.

FAQ
Q: My EA works in backtest but fails live — can you fix this?
A: This is the most common issue and usually caused by incorrect candle indexing, repainting indicators, or missing tick data. Yes, I can diagnose and resolve this.
Q: Do I need to share my strategy with you?
A: I only need the .mq5 source file and a description of what is wrong or what you want improved. Your strategy logic remains yours.
Q: Can you optimize input parameters for better backtest results?
A: Yes — this is included in Standard and Professional tiers. I run optimization passes in MT5 Strategy Tester and help identify the most robust parameter ranges.
