Here is one more reason to consider that the soybean move is almost complete....oil. I don't necessarily subscribe that grain prices follow oil, but many farmers do. Daily oil cycles typically last 40 to 60 days. Oil is on day 48 of the present oil cycle which means oil is in the timing band for a pull back in price. The chart below shows that oil has marginally broken its daily trend line this morning. A 38.2% retracement of this move would reset sentiment near $45. Eventually, I see higher prices for oil but this could be yet again a catalyst for soybeans to end this move.
On the corn side of things, there is still a lot of time for it to move with weather issues. I would not be surprised to see at least some sort of volatility spike at the report time which could allow you to get $4.45 per bushel, matching last summers high. My recommendation would be to get an order in place to sell 25% of your crop at $4.45 this morning.
