Corn is in an area predicted to form major resistance... I believe it will correct for the next few months before looking to TOP in mid of Jan 2013 around 930-940 price range.
This is an EXPERIMENTAL analysis using Gann's techniques... so don't hold your breath :)
However if your interested to see how it goes, please feel free to follow this chart.
If you have ever looked into the works of W.D Gann, I would be interested to hear your views/findings
