Code Review

Treat a strong MT5 backtest as a hypothesis, not proof.

A beautiful equity curve can still be fragile. Before trusting an EA result, check whether the result survives out-of-sample data, spread changes, slippage assumptions, and parameter variation.

Search intent

The quant or EA builder has strong backtest results but wants to know whether the result is robust enough to continue.

Stress the execution assumptions

Spread, slippage, commission, tick data, and symbol suffix differences can erase a marginal edge.

Use out-of-sample and walk-forward gates

Optimization should produce stable regions, not one magic parameter set. Walk-forward results should not be uniformly negative.
