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).
