The Tokyo Stock Exchange says it will resume normal trading Friday after an all-day outage due to a technical failure

TOKYO (AP) — The Tokyo Stock Exchange has announced it plans to resume normal trading Friday after it halted trading for the entire day due to what officials said was a computer hardware and systems malfunction. Tokyo Stock Exchange President Koichiro Miyahara told reporters a device within the bourse’s huge trading system failed early Thursday. Backups did not kick in following the hardware failure. There was no indication that the outage resulted from hacking or other cybersecurity breaches. The exchange said that restarting the system during the trading day would have caused confusion. But the outage left traders with quote-less screens and brokerages fielding a flood of calls from frustrated investors.
