Ralph Ivan Simeon

I build and audit automated trading systems for MetaTrader 4 and MetaTrader 5.

MQL5/MQL4 development: Expert Advisors, custom indicators, trade panels and utilities. I work the way a strategy should be built - rules written down first, then coded, then run through the Strategy Tester on real tick data across multiple symbols and periods before a single lot goes live.

Risk is where most EAs die, so it is where I spend the time: position sizing from account equity, per-trade and daily loss caps, spread and slippage guards, news and session filters, correlation limits, and recovery behaviour that does not martingale its way to a margin call.

Around the trading code I also build the software that supports it: pre-trade scoring engines, trade journals with encrypted backup, licence-key activation, live price feeds, and dashboards. Full-stack background (TypeScript, React, Next.js, Node) if a strategy needs a web or mobile side.

Based in Dubai, working with clients worldwide. Clear specs, fixed deadlines, and all communication inside the MQL5 order.
