Banzai created a Bollinger Band Squeeze indicator that incorporates Keltner bands. The grayed out patches on the chart are from that indicator and are meant to help identify consolidation zones. On this chart the BB colors are turned off. The visual of the BB lines can get a bit messy on the chart. post1295540205.html#p1295540205 If you search, you can probably find an mt4 version of Banzai's indicator
