Description
Wilder's relative strength index
Syntax
RSI(len)
Parameters
len - formula specifying a number of bars
Notes
Calculation uses the original Welles Wilder formula. Wilder's exponential smoothing is equivalent to using 2*len-1 in a regular exponential moving average.
It's a little-known fact RSI(len) crossing above or below 50 is the same as C crossing above or below EMA(C,2*len-1).
