Hi Pro-Codeers,

我得到了警告。"检查运算符的优先级，可能出现错误；使用括号来澄清优先级"

if ((STC115)||(STC185)&&(Ask>emaFilter && ADXmain>25))

{

OpenBuy();

}

看起来 ...AND (Ask>emaFilter) 语句也被 MT4 忽略了。

谁能提供建议？

提前感谢您!

你可能应该这样写。

如果((STC115) || (STC185)) && (Ask>emaFilter && ADXmain>25) )

但这主要取决于你想测试的具体内容。这个警告是因为以前&&(and)和||(or)的优先级是不同的--他们颠倒了，现在所有这些逻辑比较必须被检查。

嗨，Mladen。

非常感谢您的建议。我将试一试!你总是很有帮助!

用简单的话说，在EA开仓交易之前，所有三个括号都应该变成真。

我想你的代码会提供这个功能。

衷心的问候。

谁能帮我解决以下问题？

我正在使用一个艾略特波浪脚本来手动标注波浪。该脚本在图表上放置了8个不同的对象（i,ii,iii,iv,v,a,b,c）。

一切运行正常，但删除这些对象却很费劲。因为我必须点击每个对象（i,ii,iii,iv,v,a,b,c），才能删除它们。我想在代码中添加一些东西，使我能够突出所有的对象（i,ii,iii,iv,v,a,b,c），只需点击一下对象。我已经搜索过了，但我找不到我需要的功能。

(我不是要找一个删除图表上所有对象的脚本。）

先谢谢你
