不能运行使用 Visual Studio 2015，MetaTrader 终端 4 的带有 [ nquotes ] 的简单 Expert Advisor

Question

不能运行简单的专家顾问。 Wnd.dll - 来自“bin”文件夹的文件，使用 VS2015 创建。

Wnd.dll 文件位于正确的“MQL4\Libraries\”文件夹中。
所以我尝试运行这个 Advisor在实时模式下，但什么也没发生。请帮助我做错了什么。

Answer 2

nquotes 软件包仅适用于演示帐户，除非您购买了该库。整个解决方案进入您的项目存储的文件夹中。项目通常是 class 库项目，并且需要一个可执行项目来调用 DLL..而且看起来您的文件位于错误的目录中。而不是在 c# 中。
