Grains saw mixed trading on Tuesday as December Corn futures and November Soybean futures had small gains and losses respectively. December Chicago Wheat futures gained $0.02, reaching its first close above the 20-day moving average since July. The USDA's weekly crop progress report showed corn conditions unchanged at 71% good to excellent and soybean conditions up 1% to 69%. Meanwhile, a recent crop tour estimated yields below the USDA's forecast, which may lead traders to wait for further harvest data.
