Thank you very much for detailed response. Do you think you are jumping software because you do not have enough confidence in it because of its previous history or your own analysis is superior to it? I looked into introduction which gave me Idea it is a trend following system with 2 moving averages and some logic base neural network input in it. I think I have figured out what kind of MA they are using. I ran test last night and it gave 99% same result with end of day data on QQQQ. My program can not give intra day projection but for QQQQ normal range is 1 %.
