Mario Rui Chaves Da Costa / 个人资料

Bought or built an EA that looked great in backtest but you're not sure it's real? Before you risk money, I stress-test it for what backtests hide — real costs, overfitting, and out-of-sample robustness — and give you a straight verdict: holds up, breaks down, or inconclusive. No signals, no hype, no profit promises — just an engineer's honest second opinion that can save you from a costly mistake. Send me your backtest report + rules and know exactly where you stand.
