Description
RSI as a function
Syntax
RsiF(expr, count)
Parameters
expr  data series formula
count  lookback period
Notes
The standard RSI indicator always uses the series of closing prices for its calculations.
This function makes it possible to calculate RSI for any series of values.
Calculation uses the original Welles Wilder formula.
Wilder's exponential smoothing is equivalent to using 2*len1 in a regular exponential moving average.
This function supports ultrafast onepass calculation when used in the Data Section with a nonvariable count.
