BB's are nice tools and tell you when you can expect runaway upside moves to get back to crawl speed and other things.

Standard BB's are just a 20 sma with 2 deviations.

I run one chart with both a 20 and 10 base and and that is useful.

The other BB I run is 72 and I think picked it up from Bob Hoye (apologies if it was someone here).

Having some computer problems so here is just an XAO for 3 years with 72 BB.

It looks a bit better on my charts (?) but over 30 years is a pretty good indicator for longer term positions. Allow a smidgin of latitude on the mid line.
