Grains end lower after a non eventful WASDE.  Oliver Sloup, Blue Line Futures, says grains saw some profit taking heading into the weekend with row crops seeing harvest pressure and focusing on South American weather, with rain chances in Brazil.  He says a shift in election polls giving Trump a slight edge may have also played into China tariff talk which would be negative.  Live cattle futures hit chart resistance and ended lower, despite steady to $1 higher cash trade.  Lean hogs made new highs for the move in all but the October as funds continue to buy.
