[存档!]任何菜鸟问题,为了不使论坛变得混乱。专业人士,不要路过。没有你,哪里都不能去 - 4. - 页 406

 
Roman.:

1.同样,也是如此。

2.学习 如何使用谷歌!

非常感谢您!这似乎已经奏效。

 
Vinin:


你是否尝试过处理这些错误?

有几个条件。

1.第二个工具必须在市场概览中打开。甚至更好的是,如果有一个具有正确时间框架的图表打开(虽然不一定)。

2) 必须没有4066的错误。

3) 应该提交整个代码,而不仅仅是你认为问题所在的一部分代码,以供审查。

谢谢你的回答。有很多错误。我给了你一个代码部分,因为没有它,编译就成功了。以下是代码的全文。

为什么你决定MQL4支持函数的嵌套?

是什么让你认为MQL4支持嵌套函数?

谢谢你,但你能不能解释一下哪个函数被嵌套了,同时对你的代码进行评论。

FAQ:

我可以说俄语吗? 我是初学者。

请对代码的某个部分进行评论。

double Ratio(string lsSymbol, int lnPos) {
   double res=0;
   int shift=iBarShift(lsSymbol, 0, Time[lnPos]);
   double a = iClose(NULL, 0, lnPos);
   double b = iClose(lsSymbol,0,shift);
   if (b>0) res=a/b;
   return (res);
 

问候!

你能告诉我代码有什么问题吗... 不明白到底是什么问题,我该如何解决?
