Hello Marek,
I am glad to hear from you. To be honest, I used to believe the same – the more data, the better. But with the time, I saw that the generator is capable of finding robust strategies with many counts of trades, even if we use a small number of bars. And that is better for me.
We have more active strategies this way, and at the same time, we depend more on the recent data.
And of course, the generator works much faster :)
