This is why I built these models. Market closed at only -.29% down, but in reality only 145 of stocks in the index closed in the green. The selloff today didnt recover as much as the closing price would have you think... The comeback in spot was mostly driven by just a handful of large cap stocks.
Just a side note, I'm renaming this model as the MBAD Indicator going forward. Would you guys be interested if I hosted this chart live and updated daily on a website? If so, I can throw something together soon. Let me know!
