Try this MS ATR-based volatility indicator:

================
Volatility - ATR
================
---8<-----------------

The basic premise of the Bollinger's bandwidth indicator is to
measure volatility, but it doesn't do this too well.
Volatility as measured by this indicator not only appears late
(as with all lagging indicators), but actually increases after
the event.

Marco, plot your indicator on a chart with a big sudden price move
(say, 20~50%), and the problem becomes evident.  Normalizing the
indicator will not fix it.
