Hi Petko, I have encountered the same problem as jospjn described. I downloaded the data from Dukascopy and set the limit to 200,000 bars. After I uploaded the data into EAS I modified only the swap long and swap short numbers according to the “Symbol Specification” from my MT4 terminal. I use 200000 bars for M15/M5/M30 time frame as I assume that the more data I use the more accurate strategy EAS. I can only get very limited number of strategies generated if I turn on Monte Carlo validation and sometimes even no strategy generated. Is it because I used too many bars? What have I done wrong?
