TrendLinePeaks

Syntax

public TrendLinePeaks(DataSeries ds, double reversepct, bool uselogscale, string description)
public static TrendLinePeaks Series(DataSeries ds, double reversepct, bool uselogscale)

Parameter Description

ds	Source Series
reversepct	The reversal percentage used to determine peaks and troughs
uselogscale	Pass true to project trendlines on a semi-log scale, otherwise false

Description

TrendLinePeaks and TrendLineTroughs were not published in TASC Magazine. These indicators facilitate creating a trendline strategy by calculating the projection of the trend line resulting from the two most recent peaks determined by reversepct (the reversal percentage). Pass true to the boolean parameter uselogscale to project trendlines on a semi-log scale.
