Valeriy Yastremskiy 也许是因为代码不完整，因为我删除了所有不必要的功能。

Valeriy Yastremskiy #:

说实话，我不明白Kim的逻辑，为什么条形时间超过设定值和计算条数为负数的条件下，计算条数大于条数，Barz))))。而同时，它只是纠正了自定义参数)

而且，它甚至没有显示用户弄错了的提醒)

从逻辑上讲，如果指定了NumberOfBars（大于0），那么时间就会被忽略，只考虑最新的条形图。

但用户可能会在日期上犯错，或者如果在报价中出现漏洞，那么就不会打印出任何东西，它只是返回DivideByZero :-)

嗨，

，谁能知道如何将报价从mt5转换到mt4？或者有什么方法可以利用mt5到mt4的更好的历史，除了TDS2😊。

出口/进口

所以mt5有不同的报价格式，mt4不会读取它们，这就是问题所在...😎

MT5导出到csv，MT4读取所有内容

为什么我需要除以点？
...

我强烈推荐它。

s+=MathRound((High [i] - Low [i]) / Point);

否则你会得到一个 "哎呀"））。

void OnStart(){
   double first=0.00001;
   double point=0.00001;
   for(uint i=0;i<10;++i){
      double value=NormalizeDouble(first+i*point,5);
      int res=(int)((value-first)/point);
      if (res!=i)
         PrintFormat("Alert: (%.5 f-%.5 f)/%.5 f!=%u, but ==%i",value,first,point,i,res);
   }
}

如何使指标窗口完全隐藏价格图表？

我不能通过ChartSetInteger(0,CHART_HEIGHT_IN_PIXELS,0,0)来实现，我必须先设置指标的大小，然后再把价格窗口的高度加进去。

int chart_height=(int)ChartGetInteger(0,CHART_HEIGHT_IN_PIXELS,0);
IndicatorSetInteger(INDICATOR_HEIGHT,200+chart_height);

然而，如果你在底部打开订单窗口，指标窗口的尺寸就会变得比屏幕尺寸大，而且梗概又会显示价格。

我不知道如何测量订单窗口，此外，它一直在变化。

该怎么做？

唯一的问题是关于这句话

  Label1Buffer[i]=iStochastic(_Symbol,TimeFrame,StochPeriod,3,3,MODE_SMA,1,MODE_MAIN,index)-50;

-50 冗余和阵列
