打开 MQL5 个人资料I am an Algorithmic Trader and Trading Software Developer specialized in building Expert Advisors and indicators for MetaTrader 5.
Through Valforex, my professional brand, I design, test and refine automated trading systems that turn discretionary strategies into structured, rule-based algorithms — with risk control built in from the first line of code.
What I work with
Expert Advisor development in MQL5
Custom indicators (Price Action, Fair Value Gap, Market Structure, Liquidity)
Trading automation and strategy development
Backtesting, forward testing and optimization
Risk management and capital preservation systems
Instruments: NAS100, XAUUSD and major indices
HOW I WORK
No strategy reaches a live account before it is fully understood and measured. My validation process covers:
Complete review of the strategy logic and its market assumptions
Historical backtesting across multiple periods and market regimes
Maximum drawdown, trade count, profit factor, win rate and mathematical expectancy
Forward testing on demo accounts under real execution conditions
Defined maximum risk per trade and maximum daily loss
Ongoing monitoring of live performance
When evaluating any EA — my own or third-party — I look at strategy type, recommended instruments, timeframes, trading sessions, stop loss and take profit logic, risk per trade, maximum open positions, correlation with other systems, historical drawdown and VPS requirements. The goal is never to stack robots on an account; it is to understand exactly what each one does and when it fails.
WHY MQL5
I use this community to develop and publish my own MQL5 solutions, test systems in a controlled environment, analyze backtest results, and exchange knowledge with other developers and algorithmic traders.

DISCLAIMER
Past backtest results do not guarantee future performance. My objective is to evaluate strategies systematically, understand their behavior under different conditions, and manage risk before deploying capital.
