The USDA's website is all you need: http://www.usda.gov/wps/portal/?navid=AGENCY_REPORTS&navtype=RT Here it is in a nice little calendar form... http://www.usda.gov/wps/portal/!ut/...eginday=ALL_DAYS&beginmonth=10&beginyear=2009
When the grains are moving in the same direction as the seasonal tendency, you can focus on trades in that direction. MRCI.com is a great site for seasonals. If you know how to use the COT report, that is also a great tool for the daily/weekly direction and may sway you to hold a winning position overnight or turn it into a swing trade.
should be a very volatile friday and then monday when you look at this for the Grains http://www.usda.gov/wps/portal/?navid=AGENCY_REPORTS&navtype=RT
