MT4 & MT5 / MQL Specialist — XAUUSD & Risk Management

With over 10 years of active trading experience in XAUUSD (Gold) and deep hands-on expertise in automated trading systems, I specialize in diagnosing, modifying, and validating Expert Advisors for both MetaTrader 4 and MetaTrader 5 (MQL4/MQL5).

Having traded Gold across all market regimes, I understand that an EA's failure is rarely just a code syntax error — it's usually an issue with execution logic, slippage handling, basket risk management, or session filters under real market volatility.

Services I provide:

EA Bug Diagnostics & Fixes (MT4 / MT5): Fixing non-entry issues, duplicate orders, trade-server retcode errors, invalid stops, and session timing bugs.

EA Risk & Order Controls: Adding daily max loss limits, equity protection, basket trailing stops, session filters, and dynamic position sizing.

XAUUSD Strategy & Execution Audit: Validating EA logic between Strategy Tester assumptions and live runtime behavior on Gold.

I focus on root-cause execution analysis and practical trading logic rather than simply making the code compile.
