So everyone was miserable at 20K??
apparently we haven't reached "misery" until the index is < 27. i guess anything above should be considered no signal. before the recent signal, we hadn't seen "misery" since 2016.
According to this chart everyone got really miserable during the run from 8K-20K... It seems more like its based on the amount of bidrectional volatility opportunities for bearish daytraders. Not very useful.
i think it looks like that because it's a laggy indicator, and because of the "stairs up, elevator down" effect. it reacted really strongly to the november plunge to $5400 and didn't really recover until we were near the top.
the more i think about it, it just reads like an overbought/oversold momentum indicator.
