I will code, fix or backtest your metatrader 5 mql5 expert advisor
AI Automation Developer, Markets and Data
About this Gig
I build clean, reliable Expert Advisors for MetaTrader 5 in native MQL5 the same engineering I use on my own live trading systems (breakout EAs running on indices like HK50 and JPN225).
What I deliver:
- Custom entry/exit logic from your rules, screenshots, or existing indicator
- Proper risk management: percentage-based lot sizing, max-lot safety caps, free-margin checks
- Time/session filters, spread & slippage protection, trailing stops
- Auto-correction for broker quirks (wrong TickValue, symbol suffixes)
- Optional trade logging to CSV or a Supabase/SQL database for a live dashboard
- Full MT5 Strategy Tester backtest report so you see the numbers before going live
I don't sell "holy grail" bots I turn your strategy into solid, maintainable code. Message me your rules first and I'll confirm scope and price.

FAQ
Will it work on my broker?
Yes — I handle symbol suffixes, tick value and digit differences. Tell me your broker.
Can you fix/upgrade an existing EA?
Yes, send the .mq5 source. Without source I can rebuild from behavior (Standard tier).
Do you guarantee profit?
No honest dev does. I guarantee the EA executes your logic exactly and safely.
MT4?
I focus on MT5/MQL5. Small MT4 jobs possible — ask first.
