Searching for "the best MT5 Expert Advisor" leads to a sea of robots with spectacular backtests and non-existent live results. A pretty backtest is the minimum, not the proof. Here are the criteria that separate a usable EA from a fitted curve.
Why 90% of MT5 EAs fail live
- Overfitting. Parameters optimised to fit the exact past. On new data, they break.
- Hidden martingale. Smooth curves that rise in a straight line… until the drawdown that wipes the account.
- Poor-quality backtest data. No real spread, no slippage, fake "every tick" modelling.
Criteria to choose an MT5 EA
- Backtest on real tick data with 99% modelling quality, variable spread included.
- Walk-forward, not just in-sample. An EA that works on data it never saw is the only thing that matters.
- Transparent risk management. Fixed risk per trade, real stop-loss, no martingale recovery.
- Verifiable results. A live account on MyFxbook/FXBlue, not screenshots.
- Prop firm mode. If you will get funded, the EA must respect daily drawdown and a news filter.
Free vs paid EA
There are decent free EAs on the MQL5 Market to learn with, but they are usually simple strategies (moving-average cross, RSI). A serious paid EA invests in risk management, prop mode and support. What you should never do: pay a monthly subscription for a robot with no verifiable live results.

EAs are tools. They do not guarantee profitability. Trading involves risk of capital loss.
