I can guarantee you that My Fx Book and even Meta Trader do not show the correct open trade draw down. The closed trade DD is fairly accurate but the open trade draw down is not even close.
Last year I was running a $10k live account and ended up with a -$3500 floating loss (35% open trade draw down) at one point, and My Fx Book only showed 18% DD. For myself closed trade DD is very important, but most people seem to ignore open trade DD which to me is even more important for blowing up any account.
That back test above does not show modelling quality, it only shows history quality which is not the same. I use Tick data Suite with tick data and get 99% modeling quality, which is pretty accurate but does not guarantee the same future results by any means.
