下午好!你知道，我的经文中有些地方不对劲。当我把它拖到图表上时，根本就没有发生什么。

在每一次打勾时，开始是不可避免的，但可以在其中提供必要的条件。

下午好!你知道，我的经文中有些地方不对劲。当我把它拖到图表上时，根本就没有发生什么。我如何使用它？

paladin80:

归一化后，数字发生变化，例如

另一件事是当你把它打印出来时，用DoubleToStr，例如。

而如果你在归一化后将其打印出来，它是这样的。

谢谢你。

下午好。

我需要只计算最后两个买入头寸的总利润。我如何重写代码？

double profits_buy_2pos()
{
   double pr_buy = 0;
   int cnt = 0;
   int OpenOrders=OrdersTotal();
   for(cnt=0;cnt<OpenOrders;cnt++)   // scan all orders and positions. ..
   {
     OrderSelect(cnt, SELECT_BY_POS);
          if (OrderSymbol()==Symbol() && OrderMagicNumber()==magic && OrderType() == OP_BUY)
          {     
          if (OrderType()==OP_BUY) 
          {
            pr_buy+= OrderProfit();
          } 
          }                               
   } 
return(pr_buy);   
}
