Cash History rows can carry a weekend calendar date (Sunday-evening activity attributed pre-roll), and those slipped through the holiday combining as their own trading day — accounts traded only across the Labor Day Sun/Mon/Tue stretch read 2/5 instead of 1/5. Weekends never clear at CME any more than holidays do, so treat Saturday and Sunday as unsettled dates and roll them forward with the rest of the stretch.
