A sustained move over $1328.60 will indicate the presence of buyers. If they can generate enough upside momentum then look for buyers to take a run at the June 14, 2018 top at $1337.80. The key Gann angle to watch is at $1321.50. This angle has been guiding the market higher since January 24. Look for a technical bounce on the first test of this angle. If it fails then look for the selling to extend into the major Fibonacci level at $1319.70.
