Using 3PM EST prices to refresh our models, here's where we wash out on the SP500:

Negative "Trend" Line resistance = 886

SELL "Trade" = 833
BUY "Trade" = 747

Provided that the VIX closes above 64.58, the US$ closes weaker, US Treasury yield curve continues to flatten, and the SP500 closes under that 833 line, watch out below. You have -10% downside from here.
