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.

Every manual trader has lived this night. You open a trade with a clear idea. Price moves against you. You hold, because closing means admitting the loss. You add a second order to improve the average — price keeps going. Third order. Fourth...

HyperRecover: rescata tus operaciones con pérdidas. Cierra con beneficios. Ya conoces ese momento. Entraste en una operación en la que creías. El precio se volvió en tu contra. Te dijiste a ti mismo: «Se recuperará». No fue así. Añadiste otra orden para reducir el precio medio… y el precio siguió bajando. Ahora tienes 3, 5, 8 posiciones en rojo, la pérdida flotante es mayor que las ganancias de una semana y cada nueva vela empeora la situación. No puedes cerrar la operación: eso consolidaría la

You found a gold EA, ran a quick backtest, saw a smooth equity curve — and the first week live looked nothing like it. Before blaming the EA, check how you tested it. On XAUUSD the tester mode can change the result more than any input...

Most gold EAs fail a Prop Firm challenge for the same reason: one deep drawdown day. Hitting the profit target is not the hard part. Getting there without ever touching the daily-loss or max-loss limit is. HyperVirtual MT5 was built around exactly that problem...

Many traders test an EA with a small deposit first, then ask the real question: what happens with a bigger account? In this post we run HyperVirtual MT5 v1...

Gold does not behave the same way at 3 a.m. as it does during the London open or the New York overlap. Yet many Gold EAs trade around the clock with one fixed rule set, then leave you wondering why the same strategy looks great in one week and painful in the next...

HyperVirtual MT5 now comes with two built-in trading profiles: Aggressive and Safe . Both run the same Virtual-First engine on XAUUSD M1 — the difference is when and how strictly the EA allows a Virtual Basket to be promoted to real trading...

W hen evaluating an Expert Advisor, it is easy to look at a profit curve, a percentage return or a screenshot and form an opinion immediately. There is a more useful question: Can you reproduce the test yourself? That is the approach we recommend with HyperVirtual MT5...

Most Gold Expert Advisors react to a trading signal by opening a real position immediately. HyperVirtual takes a different approach. Instead of risking real capital on every initial signal, HyperVirtual starts each trading cycle with a Virtual Basket...
