need volatility indicator

[NinjaTrader_Bertrand]

You're doing a division here, while the other one substracts the values - which would lead to different outcomes, none is better just what you prefer seeing.

Ok,i see.thank you!

The main code portion would be -

double bandwidth = Bollinger(BB_StdDev, BB_Period).Upper[0] - Bollinger(BB_StdDev, BB_Period).Lower[0];

So it's substracting the lower from the upper band of the given period and deviation.

Hi Bertrand, I came here looking for some kind of NT 7 (or 8) volatility indicator. Would subtraction of the BBs work possibly? Or, what else would you suggest? Thanks in advance.

seeseea, that could work yes but would be very closely tied to the per default shipped StDev indicator.
