Hey Bogdan,
Yes, you got it right. Usually, we backtest all of the EAs with 200 000 bars which is enough. And for M1, this is since the beginning of this year.
Many traders do not realize that backtesting M1 EA on 200 000 bars is the same as backtesting M15 EA on 200 000 bars.
The only difference is that the backtest on M1 is for the last 8 months, and for the M15 it is the last 8 years.
And yes, I will regularly update the EA whenever it’s needed.
Cheers,
Petko A
