Subject: Timing: Zweig Breadth Thrust indicator

Seeing that there have been some timing posts lately, I was wondering if anyone had interest in the Zweig Breadth Thrust indicator.

It measures when there is a quick switch between a selling pressure and buying. The indicator triggers when a smoothed Advance/Decline goes from below .4 to over .6 in the span of 10 days.

It looks like it might happen today. It is rare ( I think ~15 occurances since 1945 ) and has a very strong record of positive returns.
