About this Gig
Are you a forex trader who needs a working Expert Advisor but can't code? Or do you have a broken EA that just won't run right?
I build, fix, and backtest Expert Advisors on both MetaTrader 4 (MQL4) and MetaTrader 5 (MQL5).
What I can do for you:
- Build a custom EA from your strategy rules (entries, exits, TP/SL, trailing stop)
- Fix bugs in your existing MT4 or MT5 EA/indicator
- Run a full backtest and deliver a clear performance report
- Implement fixed or martingale lot sizing logic
- Add filters like max daily trades, session filters, or trailing stop automation
Supported platforms:
- MetaTrader 5 (MQL5) primary
- MetaTrader 4 (MQL4) simple fixes and builds
Why work with me:
I'm a software engineering student with hands-on experience building and testing live EAs on MT5. I actually trade myself so I understand what traders need, not just what the code says.
Just describe your strategy in plain English and I'll handle the rest. Message me first if you're unsure whether your project fits.

FAQ
What information do I need to provide to build my EA?
Just describe your strategy in plain English — entry conditions, exit conditions, lot size preference, TP/SL values, and any special rules. You don't need to write any code.
Can you fix an EA someone else built?
Yes. Send me the .mq5 or .mq4 file and describe what it's supposed to do vs what it's actually doing. Most simple bugs are resolved within 24-48 hours.
Will the EA work on a live account?
I build and test on MT5 Strategy Tester. Live performance depends on your broker and market conditions. I deliver working, tested code but cannot guarantee profits.
Do you work on MT4 as well as MT5?
Primarily MT5/MQL5, but simple MT4 fixes and builds are possible. Message me first to confirm your project fits
How long does delivery take?
Bug fixes: 1-2 days. Backtest reports: 2-3 days. Custom EA builds: 5-7 days depending on complexity.
