Commodity Channel Index

Commodity Channel Index (CCI) indicator is an oscillator that measures an asset's current price level relative to an average price level over a specified period of time. It is used to determine a new trend or to warn about extreme conditions.

In FinancialChart, you need to use a CCI object to work with Commodity Channel Index. See the following code snippet that demonstrates how you can use CCI indicator. The code snippet uses a class DataService whose code can be seen by referring to Average True Tange.
