It's a risky trade to buy or sell corn at this stage. Corn is at no man's land so it could either go high or low. We have seen corn go past $500 commonly after 2007 which was a rare event before. I can't predict the future but I can see why corn will make new support in this region.
$550 - risky $500 - good opportunity to buy $450 - great opportunity to buy $350 - buy corn with all your money. You will make a fortune.
