After the outage that outraged investors for almost four hours last week at the Australian Securities Exchange (ASX Limited, ASX:ASX), the cause has been revealed.
Internal investigations show it was the attempted upgrade of the ASX equities trading platform ASX Trade that caused the stall in systems.
The ASX maintains it had nothing to do with the introduction of rival Chi-X, which launched yesterday and saw almost $4 million in shares change hands in more than 800 trades in a limited market that offers six stocks and two exchange-traded funds. The ASX, however, performed about $4.3 billion in trades yesterday.
The ASX Limited (ASX:ASX) reported a profit of $352.3 million for the six months to June.
