Quote from EricP:
From the CBOT website:
Thursday, April 17:
Open auction: Financial* contracts close at 12:00 noon. All other open auction contracts (Agricultural and Stock Index) close at their normal times.
Electronic a/c/e trading: Financial*, Metals and Dow/AIG Indexsm contracts close at 12:30 p.m. All other a/c/e trading closes at normal times. Overnight a/c/e/ trading closed.
=> My interpretation of this is that the bonds close at 1PM Eastern (noon central). Can anyone else confirm the actual closing time...
