MQL4/MQL5 developer - Expert Advisors, indicators and strategy validation

I build clean, well-tested Expert Advisors and indicators for MetaTrader 4 and 5, with a focus on rule-based strategies and solid risk management.

What I can do for you:
- Expert Advisors from your rules: entries, exits, trailing stops, break-even, time and session filters, news-time pauses.
- Risk management: fixed lot, % risk per trade, daily loss limits, max open trades, equity protection.
- Conversion of strategies to MQL5 (including StrategyQuant X exports) and MQL4 to MQL5 ports.
- Backtesting and validation: Strategy Tester reports, out-of-sample checks, Monte Carlo, walk-forward.
- Fixing and improving existing source code.

How I work:
- I confirm every detail in the technical specification before I start, so you get exactly what was agreed.
- Code that compiles without errors, works on hedging and netting accounts, and checks broker limits (minimum lot, stop levels, margin).
- A demo build and a Strategy Tester report before delivery. Source code included when it is part of the order.
- I develop with the help of AI tools; every line is reviewed and tested by me before delivery.
- I never promise profits: I deliver software that does exactly what your rules say.
