Class WSMA

Wilder's Smoothed Moving Average (WSMA) Type: Trend

Developed by John Welles Wilder (Jr.) to help identifying and spotting bullish and bearish trends. Similar to Exponential Moving Averages with the difference that a smoothing factor of 1/interval is being used, which makes it respond more slowly to price changes.

Synonyms:

Modified Exponential Moving Average (MEMA)
Smoothed Moving Average (SMMA)
