Glitches delay ASX, Chi-X trading

Updated: Impacts opening time and afternoon trading.

System issues have delayed the opening of the Australian Securities Exchange (ASX) equities market and alternative trading venue Chi-X Australia.

An ASX spokesperson said the problem stemmed from an issue with a component used to manage individual stocks.

“ASX is working to rectify the issue and open the market in an orderly manner as soon as possible," the spokesperson said.

Equities traders – including at CommSec and HarbourSide Capital - began warning customers of the issues as ASX reached its normal opening time of 10am AEST.

A Chi-X spokesperson said the ASX issues had impacted the "orderly operation" of the Chi-X market, and "accordingly the Chi-X market open this morning will be delayed".

Pre-open for equities trading on the ASX began at 11.10am, with the first stocks scheduled to begin trading from 11.30am AEST.

"All stocks [will be] available after the normal rotation process by 11.40am," the ASX spokesperson said.

"ASX is continuing to work with its technology vendor to prevent a recurrence."

Chi-X said it would open at 11.30am AEST.

"It is currently intended that the remainder of the Chi-X trading schedule for today will be unchanged, however participants will be advised immediately if there are any amendments," it said.

Updated, 2.47pm AEST: The ASX has put the market back in an ‘enquire’ session state, which halts trading, "due to further issues."

The ASX later advised the markets would not reopen for trading on September 19.
