荷兰

Trader & systems developer focused on structured, rule-based strategies. I build robust trading tools for MT5 and TradingView (Pine Script), designed for clarity, efficiency and real market conditions.

My primary focus is developing professional tools under my own product line. Selective custom development for MT5 and Pine Script is available for serious projects.

No hype, no unrealistic claims — only practical execution support.
