Here's another perspective of corn to consider. When/if price reaches the 660 level (and it looks like it's gonna) it will have some pretty stout and healthy looking down trendline and horizontal resistance to deal with. If it breaks thru the 660, then your target of 685 would not be far fetched at all. With a few back to back limitup days it could easily achieve your target and much more. With the news about a big heat dome settling in over the midwest that Limitup mentioned in another post it could quite conceivably go to the moon this summer.
