CExpertSignal

CExpertSignal is a base class for trading signals, it does nothing (except CheckReverseLong() and CheckReverseShort() methods) but provides the interfaces.

How to use it:

1. Prepare an algorithm for trading signals;
2. Create your own trading signal class, inherited from CExpertSignal class;
3. Override the virtual methods in your class with your own algorithms.

You can find an examples of trading signal classes in the Expert\Signal\ folder.
