Grain and livestock futures are mostly higher.  DuWayne Bosse of Bolt Marketing says corn and soybeans are getting pushed by strong weekly exports and more flash sales.  Corn is above both the 50 and 100 day moving averages and November soybeans are above $10 so charts are looking attractive for funds as well.  How long will the demand rally last with South America getting rain?   Wheat has been lagging row crops with rain chances in U.S. wheat areas and competition from Russia, plus the strong dollar.  Cattle rebound a day after the McDonald's E.coli story pressed the market but can cattle take out chart resistance and keep moving higher?  Hogs continue to look strong on fund buying and lower than forecasted slaughter.
