Here is more of my idiocy: You need to use weather in your analysis of the grain market (not just charts). If you did follow private weather, then you would know that there is a huge band of showers showing up on the GFS mon-tuse next week with approx 3 " of rain in the northern plains. The fear is that that system may come into the belt despite a heat dome. Funds took profits and avoid the the long side of this potential rains into a 3 day holiday. 644 July corn was a great sell resistance (took long profits @643 1/4 on that high and went short)...but you would know that resistance would hold without tracking weather. My business is to know how and what the funds are thinking.
