1) Period_Selected = EndValue( BarIndex() ) - BeginValue( BarIndex() );
When we run the AFL for the first time then obviously we have not selected the range in chart. Then will there be no error as "Period_Selected" is not initialised? Because we have not yet selected range.
In that case, how to assign a defalut value to Period_Selected if no range selected?
2) After above code, i am adding the below code:
Market_Cap_ROC_S = ROC(Market_Cap_S , Period_Selected);
But i get error:
Error 52. Invalid argument value for ROC () function. Argument range must be positive (and not Null).
How to fix it??
