EmaIndicator<T, D> class

Renders EMA indicator

An EMA indicator is a simple, arithmetic moving average that is calculated by adding the closing price for the number of time periods and dividing the total value by the number of periods.

It also has the valueField property. Based on this property indicator will be rendered.
