[cmd] Bill Williams Smoothed Moving Average SMA (SMMA)
stableDescription
Bill Williams Smoothed Moving Average SMA (SMMA)
Often used for its smoothing properties
(I'm truly flattered that after I published this for what it really shines as a Moving Average:
SmMA is now gaining momentum as a trendy Moving Average after Kraken was first to add it (together with z-score, good busy kraken...;])
Now most exchange TradingView widgets offer it as SMA (it seems they finally got SMMA right lets see if they remembered to update their Alligator approximation from SMA to SMAA ;)
Beginning to LOVE SMA and am making Guppy style bands with it already like SMA over MA and EMA most of the times)
Used in my coming Soon... ™ True Williams Alligator (with Timeframe Multiplier)
