ASX down following ICT systems failure

Trading halted as exchange works to resolve messaging problem

The Australian Stock Exchange (ASX) halted trading at 2:48 pm (AEDT) today due to an ICT error.

After investigation, it was found the exchange’s computer system was not sending trading confirmation messages to some companies listed on the ASX.

An ASX spokeswoman told Computerworld Australia that even though only some companies were affected, the whole exchange had to be shut down so technical staff could identify the problem.

“The error is not in any one sector, messages were just not being received on some stocks,” she said. “I don’t know if it was a hardware or software problem, our technical staff are still looking at it.”

It was not known if the exchange would be restored today or if the ASX would hold an extended trading session. Trading usually ceases at 4pm (AEDT).
