I posted this on Twitter last week, the Bollinger band width on 3D timeframe has only been below the 0.1 value 3 times before, each time resulted in a significant rally.
The yellow figures represent how many bars it stayed under 0.1. It is currently on 5 consecutive bars, so although it could squeeze for a lot longer, I expect it won't last much longer.
I'm long (with stops in place of course).
