updateThe Australian Securities Exchange (ASX) has halted all trading following a technical glitch this morning.
The glitch was detected in the ASX's trade system just after 10am (AEDST) this morning, allowing limited trading after the market opened. The ASX confirmed the issue, stating that consequently the market had been halted and no trading could occur.
The ASX said that it has launched an investigation into the matter and sought to resolve the issue as soon as it could, but did not comment on when market trading would resume or how many resources it had allocated to solving the issue.
The ASX told Sky News that approximately 6,700 trades were processed before the glitch ground the market to a halt.
After reviewing those trades this morning, the ASX has determined that they were valid and will stand. The market continues to remain in "enquire" mode.
The ASX is soon to come under new rules with Australian Securities and Investments Commission (ASIC) releasing a consultation paper last week with measures such as trading "kill switches".
