The Last Trade Date for CBOT Grain and Oilseed TAS products will be the First Position Day (FPD) of the front-month contract (FPD is the second to last business day in the month prior to the nearby contract month).
Trading in all CBOT Grain TAS products will be 19:00-07:45 and 08:30-13:15 Chicago time. All resting TAS orders at 07:45 will remain in the book for the 08:30 opening, unless cancelled.
TAS products will trade a total of four ticks above and below the settlement price in ticks of the corresponding futures contract (0.0025), off of a "Base Price" of 0 to create a differential (plus or minus 4 ticks) versus settlement in the underlying product on a 1 to 1 basis. A trade done at the Base Price of 0 will correspond to a "traditional" TAS trade which will clear exactly at the final settlement price of the day.
