The article provides an overview of the U.S. grain and soy complex trading expectations at the Chicago Board of Trade. It is expected to resume at 8:30 a.m. CST on Tuesday, with markets closing early at 12:05 p.m. CST on Tuesday and reopening at the same time on Thursday. Wheat prices are expected to decrease by 2 to 3 cents per bushel due to traders adjusting positions and the end of harvesting in Australia and Argentina, leading to increased supply. Corn traders expect the market to remain steady to up 1 cent per bushel, despite dry weather threatening Argentina's crop. Soybean prices are expected to increase by 2 to 4 cents per bushel, continuing to recover from four-year lows reached last week, as traders adjust positions and regular showers are expected in top exporter Brazil. The strength of the dollar could impact the competitiveness of U.S. grain exports.
