Hi Petko,
I tried as you told and must say that I am still not happy with the results. I tried to limit the data to 60,000 and 100,000 bars.
I tried JFD-Demo for the EURUSD for M15 with 60,000 bars. I left this running for 300hrs and I got generated 21,260 strategies of which none passed the monte carlo.
I also tried with METATRADER-Demo EURUSD for M15 with 100,000 bars this I left it running for 600min and got total of 36,641 strategies of which 2 passed the monte carlo.
I will attach pictures
thanks
jos
