2. When trade is done, Variable is "filled" with the a new value from the open trade http://prntscr.com/8g56qy

3. To check it i use http://prntscr.com/8g5792

But the result in the that I see when backtest is done is this http://prntscr.com/8g59n7 http://prntscr.com/8g59vi

Where is the error ??? I´m completely stopped, any help or example will be wellcome.

Thank you.
