Looking at the daily chart of the S&P 500 we can see that the index is coming up to re-test the 200 day SMA. The Advance Decline line is coming up on an important point in an ascending wedge. The Pring Special K is also at an important point, a resistance level that hasn't been seen since June 2016. A break through the resistance levels on both indicators and the index would lead me to expect it to continue to the next resistance at 2818.77.
