CExpert

CExpert is a base class for trading strategies.

It already has some elementary trading "skills". It has built-in algorithms for working with time series and indicators and a set of virtual methods for trading strategy.

How to use it:

Prepare an algorithm of the strategy;
Create your own class, inherited from CExpert class;
Override the virtual methods in your class with your own algorithms.

Description

The CExpert class is a set of virtual methods for implementation of trading strategies.

Note

A position is recognized as belonging to an Expert Advisor and managed by it based on the pair of properties m_symbol and m_magic. In the "hedging" mode, multiple positions can be opened for the same symbol, therefore the m_magic value is important.
