[C#]
public static SeriesCollection TrendLinePower( 
   SeriesCollection sc,
   double step,
   int forward,
   int backward
);

Parameters

sc

A collection of series objects. For example, to evaluate this indicator for two series you will need to pass a series collection containing this two series.

step

The distance in the x-coordinate between two adjacent extended points. Please note that this also corresponds to the distance in the x-coordinate between the highest and lowest original data point and the first (above or below) additional evaluation point.

forward

The number of additional evaluation points which are evaluated above the x-coordinates of the original given data set.

backward

The number of additional evaluation points which are evaluated below the x-coordinates of the original given data set.

Return Type

A series where the k-th element of the array represents of k-th point (i.e. { x_k, y_k }) of the total set over which the fitted function is evaluated. The total set over which the fitted function is evaluated consists of the `backward' points, original data set points and the `forward' points.
