The indicator represents a moving average that resets its calculation period, as soon as the current standard deviation exceeds the previous one twice or more when the bar is closing.
It is useful for detecting the trade direction.
There are three adjustable parameters:
VolMA = SMA(Price, Length)
Price = Applied price PrevPrice = previous Applied price
If Abs(sDevNow) > Barrier Length = 1 otherwise Length = PrevLength+1
sDevNow = RAW / Price * sDev sDev = SQRT(VAR / Period)
VAR = POW(RAW[Period] + RawAVG
RAW = (Price - PrevPrice) / Price RawAVG = SMA(RAW, Period)
