Arnold is building their profile!

I turn explicit trading rules into testable MetaTrader and TradingView software: MQL4/MQL5 EAs and indicators, Pine Script alerts/strategies, authorized-source repairs, broker/order diagnostics and acceptance specs. I freeze timing, state transitions and positive/negative tests before implementation. No decompilation or profit, win-rate or prop-firm promises.
