Syntax

public WilsonRSIChannel(DataSeries ds, int rsiperiod, int smoothperiod, double cord, string description)
public static WilsonRSIChannel Series(DataSeries ds, int rsiperiod, int smoothperiod, double cord)

Parameter Description

ds	Source Series
rsiperiod	RSI period
smoothperiod	EMA smoothing period. Keep this low as higher numbers increase delay.
cord	Cord is the RSI value between 0 and 100

Description

The Wilson (Relative) Price Channel from Leon Wilson's article in the July 2006 issue of Stocks & Commodities magazine. The channel quantifies the relationship between price action and RSI. In reality, the channels are reverse-engineered RSI constant values displayed on price. Run the example for clarification.
