Corn, soybeans, and wheat are all higher after light overnight trading. This is the overnight chart for wheat.Soybean prices yesterday failed to break through the Upper Bollinger Band on the daily chart, a key resistance level. However, prices haven't closed below the Exponential Moving Average, either. It remains to be seen whether this will occur. This is a key inflection point for soybeans, but it will undoubtedly be driven by weather-related news.
