The continuous monthly chart for December corn only still shows a major (long-term) downtrend is in place following the bearish spike reversal from may 2021. That being said, the market continues to consolidate in a tightening range, a pattern that usually leads to a breakout, with initial resistance at the previous 4-month high of $5.92 (December 2021) and support at the previous 4-month low of $5.6925. This is not my favorite chart (similar to continuous November soybeans), as some oddities quickly become apparent. Note this past December saw a bearish outside monthly range established, a combination of activity in both the 2021 and 2022 contracts. Still, until something changes, the major high of $6.38 would be expected to hold, despite being only 65 cents above the January close of Dec 2022.
