I would like some help, or some comments about the strategy tester in MT4.
The thing is that, I tested an strategy which resulted in "Total net profit = -345" and the "Modelling quiality" was around 41%, this was for the USD/CHF.
So, I went to the History Center in MT4, and I downloaded the available data for USD/CHF, then I ran the same strategy again, on the same USD/CHF, and this time I got "Total net proffit = -2" with "Modelling quiality" 90%
My question is, how can it be that different? is it normal?, which of the results should I believe for my strategy?.
