RE: Market Breadth Extra
I thought I'd have a go at plotting some advance / decline charts. No garuntee they are accurate but here goes. I';m not sure about interpretation, it is one thing to look at other peoples examples and another to try and interpret yourself.

cummulative_value = old_cummulative_value + (advances - declines)/(advances+declines+unchanged)
The Dow Jones Industrial index plotted against the NYSE advance decline data:

Finally, for three different time periods the NASDAQ composite against the NASDAQ cummulative advance / decline:
