这些图书馆到底能不能用？

我在网上某处看到一个关于如何拆解这东西的视频，但它在创建时需要打开一些东西，不管是头文件还是其他东西。我在64KA上重新编译了代码，它成功了。好吧，事实证明，在64卡上，8字节的指针已经被看得不是很严重了，而且可能还有其他关键性的差异，人们应该大力发挥这个问题。我只是想用32位编译器来进行调试，我有一些专门为它们设计的想法。

 
你能告诉我为什么双数0.00134不能被30除以？
，它给出了一个整数和小数点后的无穷大数
，它应该是大约0.00004

Print( DoubleToString(0.00134/30) ); 0.00004467

维塔利，如果你不打印，内部计算会不会显示0.00004....或5.666666.....e ?
或者说是同样的事情？

内部计算只包括这个（一个八字节的十六进制整数）。

你好！有谁知道从MT4到快速 交易所的交易的合理复制器吗？
 

下午好。帮助


我有一个代码，没有检查是否存在未结订单。

根据规定的逻辑打开订单，但同时打开买入和卖出订单。

我们将与这些订单一起工作。

//它不需要检查订单，如果它是开放的。


如果你启用了检查功能，那么订单就不会像我们希望的那样被打开。
如果我们想避免反订单，我们应该检查第一个被打开的订单，然后打开相同的类型，直到最后一个订单类型被关闭，然后再回到检查打开条件的逻辑。

int TypeOrder(int OrType)
{
 int count = 0;
  for(int i = OrdersTotal(); i>=0; i++ )
     {
      if (OrderSelect(i,SELECT_BY_POS,MODE_TRADES))
         {
          if (OrderSymbol() == _Symbol && OrderType() == OrType && OrderMagicNumber() == Magic)
             {
              count++;
             }
         }
     }return (count);
}

而如何指出这一点，没有人理解。
有谁能给个提示，让大家明白？

谢谢你的任何提示。

谢谢你。逻辑是正确的，只使计数器正确，并正确指定条件

if (CountTrades() == 0 && body > 0) BuyOpen();     // Если нет открытых и сигнал бай
   if (CountTrades() == 0 && body < 0) SellOpen();    // Если нет открытых и сигнал селл
   if (CountTrades(0) > 0 && body > 0) BuyOpen();     // Если есть открытые бай и сигнал бай
   if (CountTrades(1) > 0 && body < 0) SellOpen();    // Если есть открытые селл и сигнал селл

谢谢你。我会研究的。

下午好。这里有一个问题。我有一个拖网。

我如何对我的专家顾问进行指定以使其发挥作用？

   if (CountTrades(1) > 0 && body < 0) SellOpen();    // Если есть открытые селл и сигнал селл
   Trail();
  }

我看到他们是这样规定的，但对我来说，不知何故，这并不奏效。

这是一个一般的问题，要指定函数工作的前，我应该怎么做？
