Today we closed corn in the "pit session" at the exact same price the open was. This is called a DOJI candle. DEFINITION- "The doji represents indecision in the market. A doji is not as significant if the market is not clearly trending, as non-trending markets are inherently indicative of indecision. If the doji forms in an uptrend or downtrend, this is normally seen as significant, as it is a signal that the buyers are losing conviction when formed in an uptrend and a signal that sellers are losing conviction if seen in a downtrend. Most traders will place greater significance on the doji when it forms in a market that is in overbought or oversold territory as noted by oscillators like relative strength index or MACD."

This combined that 484 is the exact .382 retracement of the 2008 top gives warning signals at least short term.  IMHO it a great place to put hedges back on with a stop above 486'4.  Same with wheat with stop above 754'4.

These fund are loaded with profits and IMHO are due for some profit taking.  Look for the 455-460 to provide good support in the event of a selloff later this week. 

700 WZ looks like good support in wheat and 10.00-10.10 for beans.
