Martin Jonathan Kleinbooi

I’m an algo trader and MQL5 developer dedicated to building robust, rules-based strategies for crypto and FX. My specialty is Ethereum (ETH) on higher timeframes—primarily D1—where noise is lower and signals carry more edge. I’m the creator of Donchian Confluence EA, a system that blends Donchian breakouts with Price Action confirmations (Engulfing & Fair Value Gaps) and disciplined risk management.

What I build

Confluence over frequency: Donchian breakout + PA filters to improve signal quality and avoid obvious reversals.

Risk-first execution: ATR-based SL/TP, partial profits by R-multiples, structure-aware trailing, daily risk caps, position limits.

Broker-aware logic: Respect for StopsLevel/FreezeLevel, tick-size alignment, volume min/max/step, and netting/hedging constraints.

MTF context: Optional higher-timeframe trend checks, lower-timeframe PA scan for better timing.

No martingale / no grid / no arbitrage: Just clean, reproducible logic.

How I test

Multi-year backtests with realistic costs (spread + commission + slippage).

Out-of-sample and parameter sanity checks (no curve-fitting).

Cross-symbol/broker spot checks to confirm stability.

Trading philosophy

Simplicity scales. Clear, deterministic rules beat “black-box magic.”

Risk first. Survive volatility; let compounding do the heavy lifting.

Evidence over opinion. If it doesn’t show up in the data, it doesn’t go in the code.

Support & updates
I actively maintain my products, consider sensible feature requests, and share practical presets (especially for ETH D1). If you have questions about setup, parameters, or backtesting, send a message—I read every note.

Disclaimer
Trading involves risk. Past performance does not guarantee future results. Nothing here is investment advice. My tools are designed to support disciplined traders who value transparency and risk control.
