Is backtest with mt4 tester accurate?


If it basing on repaintable indicators - absolutely not.
but if bases on "bar closed positioning" systems - 90%
also depends of broker chart history

If it would be accurate, I would be millionaire. I programmed some EA, that adopted by accident to the inner mechanism of the artificial Tick-Creation of the MT4 stategytester in the 1-minute-timeframe. What I got as result was an almost straight line of growing money in the demo account. Very impressive with huge numbers in the end, but unfortunately it was pure illusion. As I bought real tick-data to make better backtests in mt4, all illusion went down and the demo account was not growing, but declining...

The best way to backtest an Expert Advisor (EA) is using reliable trading platforms like MetaTrader’s Strategy Tester with high-quality historical data. Test across different timeframes and market conditions to evaluate performance. Use both visual and quantitative analysis, and conduct forward testing on demo accounts to ensure the EA’s real-world effectiveness and robustness.
