Selling is strong and steady. The one wrinkle is that $VXO/ $VIX while up aren't presenting big moves. So either there's a lot more downside ahead or the market is poised to bounce. My SPY puts have almost doubled and seeking to hold until end of week depending on which levels are hit and nature of the sell off. First level seeking to take profits is 177-178 SPY if we get there.
We've fallen into the orange box and below support which has held the previous 2 days.
The down vs up volume ratio in the NYSE is in the 30's which is same as the Aug low from 2015 (lower yellow bar) but not as extreme as the mini crash from 2011 (upper yellow bar)
SPY is overshooting to the downside from its channel
