Backtest and real

One developer offered me (as im am a newbie) to take part in testing his EA. The results in backtest are great. But what can be a signal that on real account i ll have the same profit or at least some profit…not loss

Back test is useless especially for an EA. The only back test that I believe on is any strategy that uses candle sticks like price action or any breakout strategy on any time frame, you can accurately check the backtest results of such strategies, but indicator based and EA are totally useless.

I agree with you on that 100%.

May be its good idea to try demo first?

results may vary between demo and live, back testing is ok, if you push through with live keep it small and contained!! let us know how it goes and best of luck

It is right if the result in demo account and real account would be different but it is almost same in the result if you used EA because EA is not affected with emotional in trading so if you tried to run the EA in the demo account and you run it in the same session and condition in real account so the result won’t be much different because the consideration will be similiar no matter the result would be same bad or same good.

Yup. Any dude who has created a reliable EA will never ever share his Golden Goose EA.
