These resistances are identified as the 50 percent and the 61.8 percent projection levels of the wave C from $3.67-1/4. This wave is capable of travelling into a range of $3.94-1/2 to $4.03.

Corn has briefly pierced above $3.85, it has a good chance of overcoming this barrier and rising more. Immediate support will be at $3.82-3/4, a break below which would indicate the resistance at $3.85 remains intact and the contract may slide below $3.81.

On the daily chart, corn faces a strong resistance at $3.86, the 38.2 percent retracement of the downtrend from $4.37 to $3.54-3/4. A break above it could lead to a gain to $3.96 while a failure may cause a loss towards $3.74.
