Using Binnary Branch Lots Determination

Hallo,

I am using A binnary tree to determine the lotsize depending on the profit of the last three orders. Is it possable that the function OrdersHistoryTotal() doenst work while backtesting? 

         OrderSelect(OrdersHistoryTotal()-1,SELECT_BY_POS,MODE_HISTORY);  
         double P5 = OrderProfit();

No,  but it reads the Strategy Tester Order history  . . . not your Live/Demo Order history.  If your EA hasn't placed any orders there will be no orders to read . . .
