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.
