Profitseer, this is an interesting approach, but even if you are right 50 % of the time about the global daily market direction, you will most probably ends up losing money with this method because, at some times, the trailing stop during market congestion period will forbid you to reach your...

Hi, Looking at the Sharpe ratio is my first attempt to find an indicator evaluating the CONSISTENCY of the returns when comparing two intradays trading systems having similar global performance (ie similar total PL, % winner, profit factor, etc..) In this area, I found the max Drawdown (or...

Breakout, As he mentioned earlier in the thread, Acrary is backtesting the SP (250 $ per pt) not the ES.... On top of that, DraXon didn't mention any rules preventing from holding overnight, so you may have largest winner/loser above/below your profit/stop level in such cases.. It would be...

I fully agree that the learning curve might be harder for IRT than on other packages because of the very extensive list of available features and I had as well my lot of frustration too while "trialing" the software. I have been testing most of the existing software package available...
