I thought I had replied to this but obviously lost it when correcting something else.  I notice you use the McClellan, both the oscillator and the summation index in your breadth charts.  Do you find them useful? 

Yep, I find they give some differences to the AD data. Although the McClellan oscillator is very similar in moves to the 10 day SMA Momentum Index. But the summation index is fairly unique.
