SYDNEY (REUTERS) - Australia's stock exchange ASX Ltd said trading will not resume on Monday (Sept 19) due to a technical problem that brought afternoon trading to a halt.

The ASX will not conduct a closing price auction, either, it added.

Afternoon trading was halted on the ASX on Monday after a delayed opening of the bourse "due to an issue with a component that allows ASX to manage individual stocks", an ASX spokesman said.

ASX's normal operating hours are between 10am and 4pm local time, but on Monday pre-open trading did not begin until 11.10am.

At 0437 GMT, the benchmark S&P/ ASX 200 index was flat at 5,294.8 points.
