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.
