Dear All,

I am trying some strategies but dont understand the use previous bar value item. When it is selected as automatic, the balance becomes low but if not selected it becomes high? What is difference. And also some bar interpolation methods. If i change it in builder and save this startegy, does it affect in trader also?
And last question, how can i test this strategy seem in live means i will see the bars will change as live but in historical values.

Best regards.
