方程的C＃代码 [英] C# Code for Equations
问题描述
我正在学习C＃，但是，我无法理解如何编写方程式。我试图计算价格的趋势和价格的动力。代码看起来像这样，不编译：

I am learning C#, however, I am having trouble understanding how to write equations. I am trying to calculate the trend of price and what momentum the price has. The code looks like this and does not compile: 这篇关于方程的C＃代码的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！

You can't just grab a single file and expect it to work all on it's own: go back to where you got the file, and get the whole project. The chances are that you need to find and include (at a minimum) the Indicator class which (presumably) defines the missing variables as part of teh base class.
