The $VIX hit a low of 12.80 on Wednesday (10/28).  So unless and until that low is breached, this is the level we monitor to look out for the first Danger Zone metric:  50%, 100%, 150%, etc, UP from 12.80.  So set an alert for VIX 19.20 (50%) and VIX 25.60 (100%).  Also, watch for the 2nd metric, which is 25% or greater 1- or 2-day increase from any day’s close.
