Welles Wilder’s Smoothing Average (WWS)
Description
The Welles Wilder's Smoothing Average (WWS) was developed by J. Welles Wilder, Jr. and is part of the Wilder's RSI indicator implementation. This indicator smoothes price movements to help you identify and spot bullish and bearish trends.
Formula
WSMA(i) = (SUM1-WSMA1+CLOSE(i))/N
Where:
WSMA1 = Wilder’s Smoothing for the first period.
WSMA(i) = Wilder’s Smoothing of the current period (except for the first one).
CLOSE(i) = The current closing price.
N = The smoothing period
