I am having issues with deleting or closing a pending buylimit. here is my coding what am I doing wrong? its probably simple

1. for(int b= OrdersTotal()-1; b >= 0; b--)
      {
                if(OrdersTotal() == 0)
                  CloseBuyStack1stLevelLimitOrder1M();
      }

   If OrdersTotal() is zero the for loop will do nothing. If OrdersTotal() is nonzero the last if statement will always be false. Either way nothing happens.
