This is the first part of a series introducing development of classes for custom indicators.
In this part I create a class for a Donchian Channel indicator.
Future parts will extend on this to include:
* A second indicator
* Inheritance
* Development of an on screen indicator using these classes
* Development of an expert advisor using the classes
* MQL5 versions
* Improvements to the basic code used in the initial class
