Hello,

I have an issue that i can't understand that drives me crazy...
My problem is with the Walk Forward Optimization (WFO) on NT7, 15min based chart.

When I run the WFO on the exact same period, the exact same parameters, etc, i get significant different performances from a day to another...

So for example, yesterday I run the WFO and get a 1.3 Profit Factor but today, using the exact same conditions, Profit Factor is 0.8. and results are different..
How is that possible???

the problem is not the difference between live data and historical data. The problem is purely a consistency issue with historical data...

Your help would be highly appreciated.

I just noticed that when i open the Output Window i have thousand of lines like this:

...........................etc............

Any idea what is wrong here?
