The "bandspeed" indicator will try to evaluate the rise in volatility acceleration, and the "bandhisto" will try to get a volatility evaluation of the period versus the volatility of the 150 last bars on a range between 0 (minimum historical volatility) and 100 (maximum historical volatility).
These 2 indicators came from the "bandwidth" as defined by John Bollinger.
We start from "bandwidth formula"
bandwidth=((sup boll band-inf boll band)/ mov average boll)*100
then we apply a 5 period moving average to the "bandwidth" and
1.) we have an oscillator like :
bandspeed=((bandwidth/moving average)-1)*100
2.) Bandhisto:
We start from bandwidth formula, then we get the maxi and mini for the bandwidth on the last 150 period
varmax=max(bandwidth,150)
varmin=min(bandwidth,150) then we apply %B formula
bandhisto=(bandhisto-varmin)/(varmax-varmin)*100
And we get the actual volatility on a range of 0 to 100.
the 150-period can be a variable...100 or 50 as the trader want !
Thanks for your help !!
