Corn has either bottomed at 319.4 or needs one more decline closer to 310.00 before a long term bottom is seen for a rally towards at least 440.00 and possibly even higher towards 519.00.
The first strong indication of the bottom being in place will be a break above the resistance-line seen near 329.00 while a break above 335.00 confirms the bottom for the rally to at least 440.00.
