Bollinger bands squeeze.
By Vladimir Gaitanoff, 2005. support<at>vglib<dot>com
This is a volatility indicator.
It can be used to determine the periods of extremes of low volatility
which usually followed by big moves.
Indicator does not show direction of the trade, only timing.
Some other aspects of technical/fundamental analysis should be employed
for direction.
There is a signal line with colored dots. Red dots indicate periods of
low volatility (sqeeze).
Green dots indicate periods of high volatility.
Indicator line crosses above and below signal line. Time trades at
historical extremes of low volatility.
It can be used for scans, for instance, to find stepper stocks before
big moves.
The original author of the idea uses it for intraday trading.
For confirmation look for sqeezes in two different time frames.
