Soybeans: Let's start with this lazy one. Simple, as there is no trend at all. DMI is , with a super low , Price is trading in the Kumo, all lines are flat, and Chikou Span hit Price candles. The range is still 1000 - 1050. A trend trader is not touching something like this. A swing trader could buy here at the range bottom wit a stop below 992.
Corn: The trend is still , and actually Corn has the best behaviour so far. Price retested exactly Kijun Sen, and popped up again. With Slow turning up, we will likely move higher again short term.
Support is 388-392. For longs I recommend to place a stop at/below 379.
Wheat: Might be a buy here, but indicators suggest to be cautious. Tenkan/Kijun is on weak Sell signal, Price is below Kijun Sen, future Kumo overshades Price and Chikou lost its open space.
However the trend and horizontal support at 566-570 is still strong.
