How to test an EA
What do you mean by testing and validating your EA?
Backtest reliable?
Forward test match to backtest?
Live result are real or not?
what?
If you want to test and make sure to buy an EA:
Run your own backtest using tick data with at least 3 years of history. If the curve looks too perfect, its likely curve fitted and won't work live (But it need more test and details).
Then forward test it on a demo for 1 to 3 months and compare the results to the backtest.
Win rate, drawdown, and trade frequency should be similar. Big differences are a red flag.
For live results, never trust screenshots. Ask for a verified Myfxbook or FXBlue or same live signals in MQL5 and check the full history including losing trades.
Also watch for dangerous strategies like Martingale or no stop loss. If lot sizes grow after losses or the SL column is empty, stay away.
To analysing your data with an AI agent, Since you only have the EA file and description, export the trade history as CSV from MT5, paste it into your AI system, and ask it to compare the real results against the developer's claims.
That's the most practical way to validate without reading the code.
