Mario Antonio Caceres Lopez

MQL5 / MQL4 developer with 3+ years building Expert Advisors and indicators for MetaTrader 5 and 4. I specialize in gold (XAUUSD) and synthetic indices (Weltrade GainX/PainX/FlipX).

What I can build for you:
- Expert Advisors from your strategy or from an existing EA's parameters
- Grid, hedge and martingale systems with strict risk control (max drawdown, equity stop, max orders)
- Trend, scalping and news EAs (EMA, RSI, ATR, session filters, spread filters)
- Trailing stop, break-even, partial close and basket take profit
- Custom indicators with alerts and on-chart panels
- MQL4 to MQL5 conversion, bug fixing and compilation errors

Every project includes clean, commented source code, documented input parameters, and a backtest in the Strategy Tester before delivery. I also know Python and C++ for data analysis and external tools.

Clear communication, fast replies and on-time delivery. Spanish and English.
