Looking back a little on this one I noted the many Bollinger Band piercings of 50% or more and subsequent activity. I remember seeing a post from MACDad about a setup he saw in this and divergence events.
An addendum of sorts to the divergence ideas posted yesterday: %R(14) and Accumulation/Distribution Index normally shadow each other. When %R prints at one of the extremes I look at the other to see the eod result.
