Just did calculation
If SPX under lower BB 7 Days (or more 8 days, 9 days), the only case was 07/29/2011.
This time, I counted on SPX under lower BB 7 days (not real, since Jan 30th not)
Longed ES1751. XIV 26.4.
shorted UVXY101.
ES down -40 pts. hit ES1735.
cannot load a chart. But look into the SPY/SPX yourself.
Use XIV, did same calculation.
XIV low below lower BB 7 days, it never happened before. This is the 1st time.
Historically, when under lower BB 6 days. its next day all went green.
