The ASX had an unintentionally short session today after a computer glitch caused the exchange to close down. The computer system that the exchange introduced in November had failed to send confirmation messages for trades in some companies. Although the glitch only affected some companies, the whole market had to be shut down to fix the issue. As a result, trading stopped at 2.48pm. The premature close saw the XJO down 6 points, completing a very placid session. It is still unclear as to whether the exchange will be ready to open at 10.00am tomorrow. Today’s price action does not instill a lot of confidence in this being the end of the recent sell off. There is some confluence for a retracement to finalise around these levels and within the next week or so if it is going to be the case.
