Computer Outage Shuts Down Trading At Chicago Stock Exchange
CHICAGO (AP) _ Trading was interrupted for more than an hour Wednesday on the Chicago Stock Exchange after computers abruptly shut down.
Exchange officials closed the floor at 1:22 p.m. CDT after the main and backup computer system went down, spokeswoman Tracy Galla said. The system was brought back up and trading resumed at 2:35 p.m., she said.
Officials said an overheated computer might have triggered an automated shutdown.
Trading normally ends on the regional exchange at 3 p.m.
