Shanghai Stock Exchange to run test after transaction delay

BEIJING, Sept 28 (Reuters) - China's Shanghai Stock Exchange will run tests on its auction and various other platforms on Sunday, the state-run Securities Times reported on Saturday, a day after an unexplained transaction delay.

Friday's delay on trades at the benchmark Shanghai Composite Index .SSEC coincided with a Chinese stock rally that followed official announcements of a slew of monetary, liquidity and fiscal stimulus this week.

All market participants can participate in Sunday's test, which will seek to identify issues with processing a large number of orders during the auction process, the report said. The test will simulate a normal day's trading and clearing.

A Shanghai Stock Exchange official confirmed that a notice about the test had been sent to brokerages and some other market participants, but was unwilling to share it with Reuters.
