I see good chances a rebound tomorrow as the short-term model from www.sentimentrader.com is way too oversold.

A clear Double Bottom is formed on the SPY 15 min chart so the rebound target could be $88.72.

Just tomorrow will be the end of a 7 trading day cycle so if the market does rise then probably it will be down the day after.
