新人对MQL4和MQL5的任何问题，对算法和代码的帮助和讨论 - 页 1292

你好。

我是个新手，所以不要骂我太多。 )

https://www.mql5.com/ru/articles/100

本文举例说明，只有在出现买入信号且没有未平仓多头头寸 的情况下，EA才应下达买入指令。 同样，在卖出的情况下--卖出条件且没有未平仓空头头寸。

在第一次测试中，我们很快意识到，不仅有一个位置被打开，而且有几个位置被打开。问题是为什么？

我阅读了EA的代码，试图理解并找到原因，但一切似乎都很好。

尝试改变

         if(Buy_opened)

它是由

         if(Buy_opened==true)

卖出的情况也是如此

[Alexey Viktorov]

MakarFX:

尝试更换

至

类似的出售

这不会有帮助。更经常地阅读文档。

大家好，我不知道如何通过CODE "画 "出一条与人字形膝盖平行的趋势线。事实上，我需要向"之 "字形的右边转移。请指教!谢谢你!

[Aleksei Stepanenko]

Александр:
"画一条趋势线，走向未来"

从一条线上的两个点，你可以找到该线上任意第三个点的价格，也是在未来（反之亦然）。

你好。
请注意"Chechako"。
我需要指出代码中的错误，因为在测试器中，EA没有打开订单...
编译器没有显示任何错误或警告，同样的日志也没有显示任何错误......。

Ivan Rodionov:

本文举例说明，只有在出现买入信号且没有未平仓多头头寸 的情况下，EA才应下达买入指令。 同样，在卖出的情况下--卖出条件且没有未平仓空头头寸。

在第一次测试中，我们很快意识到，不仅有一个位置被打开，而且有几个位置被打开。问题是为什么？

我阅读了专家顾问的代码，试图理解它并找到原因。

我曾试图帮助。我自己也是个新手。现在，关于你的问题。有几个仓位被打开是因为进行了开仓的检查，而检查时忘记了 停止。操作员返回 将控制权返回给调用程序（取自MQL5参考）。

我们必须在专家顾问的代码中添加返回的 内容（用黄色标出）。

//--- есть ли открытые позиции?
   bool Buy_opened=false;  // переменные, в которых будет храниться информация 
   bool Sell_opened=false; // о наличии соответствующих открытых позиций

   if(PositionSelect(_Symbol)==true) // есть открытая позиция
     {
      if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)
        {
         Buy_opened=true;  //это длинная позиция
         return;
        }
      else if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
        {
         Sell_opened=true; // это короткая позиция
         return;
        }
     }

此外，为防止编译器产生警告，应在买入和卖出开仓条件中再增加一个条件，以检查OrderSend(mrequest,mresult)。这个条件是由if 操作符定义的，应该是这样的

//--- отсылаем ордер
if(OrderSend(mrequest,mresult))

还应考虑到一件事。有时，在23:59:59从一个交易日转到另一个交易日时，一个已开的头寸关闭，然后在00:00:00，一个新的头寸打开。这就是所谓的展期收盘和展期开盘，这取决于特定的外汇商和其交易条件。在论坛上搜索一下，我在某个地方有一些相关信息。

问候，弗拉基米尔。

[Игорь]

你好。人们需要你的帮助。我将两个具有不同参数的锯齿形连接到一个指标中（没有错误或警告） 问题是第二个锯齿形绘制不正确。

这是代码本身 (MQL5)

Игорь:

大家好。人们需要你的帮助。我将两个参数不同的之字形组合成一个指标（没有错误或警告），问题是2个之字形不能正确绘制。

下面是代码本身（MQL5）。

一切正常--只需修正顶部的几个数字即可

[Игорь]

SanAlex:

这一切都在发挥作用--把上面的数字修正一下。

谢谢你的帮助。还有一件事，为什么一个之字形的形成和平常一样（最大，最小），而另一个只在最大处形成。
