Corn has not yet made any playable set ups. Soybean Oil, and Wheat on the other hand have been giving some good contrarian set ups the last 2 days or so.
Friday is still up in the air though, have to wait and see on that. The open was too low, and left a gap to fill. I suppose one could do a counter contrarian trade, but I never set up and functional rules for doing those.
To sell wheat, we need to see it fill the gap, and give solid signals on the intra day charts so we know it's not just bouncing around randomly.
