Attached is the 10 year chart of the NYSE cumulative Advance Decline line, which is currently testing it breakdown level for the firt time in 8 years. So in a danagerous position.

Thanks for that, I plot that on my breadth charts but they are rather jumbled and this graph is too compressed vertically to jump out like you have presented it. Is the MA 50 weeks?

Cummulative advancing / declining volume ratio tells a similar story (yellow, with 50 and 200 day averages). Cumulative new highs minus new lows in greed with 100 day MA as well.
