"ASX and its technology provider Nasdaq have identified the root cause and a resolution path to fix it. A software issue limited to the trading of multiple securities in a single order (combination trading) created inaccurate market data," the exchange said.
With Monday being the go-live date for the refreshed ASX Trade system, the exchange said Nasdaq, customers, and independent specialist third parties conducted extensive testing for over a year, including four dress rehearsals, in preparation for sending it out in the wild. ASX said the refresh is the latest generation of a Nasdaq-developed trading system used around the world.
