Breadth has been so bad that Summation (momentum) will drop -1000 tomorrow, just the 6th time in 20 years. Marked the low in 2019 and 2009, the initial low in 2002 and the start of July 2008 rally. It also meant nothing during the Oct 2008 panic 
Summation keeps falling until turns positive; in other words, aside from Oct 2008, this is about the time when a series of accumulation days (>3:1) start. Last time was positive was Feb 20 ($SPX peaked Feb 19)
Two more Summation -1000 occurrences in 1998 and 1999. All except the last one (Dec 2018) gave way to a lower low in in the following weeks. Momentum takes time to work off
Breadth: momentum ($nymo) +30 today, so Summation will rise for the first time since the peak in 5 weeks ago. Scroll up for the chart
up 17% in 3 days, the most in forever. The 3-day avg up volume (breadth) is strong but nowhere near the most in forever (lower panel). Sometimes all clear, just as often not (arrows)
now up 20% from last week. It rallied at least 20% three times during 2001-02 and twice during 2008-09. It’s not an all clear signal
Extremes in both drops and rallies like this has only happened twice before in the past 40 years - 1987 and 2008. N=2 but the low in was still ahead
Breadth: The premature talk of a breadth thrust last week (scroll up) killed by today's 9:1 down volume (major distribution)
Here’s a link to check breadth every day. Some of these take a few hours to update after the close. NYUPV:NYDNV measures accumulation (positive) breadth days; NYDNV:NYUPV measures distribution (negative)
