Tokyo Stock Exchange considers early upgrade after second crash

The Tokyo Stock Exchange is considering bringing forward an upgrade to its trading system after the system crashed for the second time in less than three months.

The Tokyo Stock Exchange is considering bringing forward an upgrade to its trading system after the system crashed for the second time in less than three months.

Last week the exchange had to close down 20 minutes earlier after its trading system could not keep up with the amount of trades. This problem came after the fiasco last November, which saw the exchange closed for most of the day after a routine upgrade crashed the system.

Tokyo is now considering adding greater trading capacity now, instead of waiting to the end of this month to do it, which it originally planned to do.

The new system is expected to increase the maximum number of executed transactions from the current 4.5 million a day to 5 million. 

Tokyo IT staff were conducting tests on the system at the weekend to see if an early upgrade was viable.

When the system closed early last Wednesday, the number of trades had hit 4.38 million.

The exchange then decided to close 30 minutes early on both Thursday and Friday to alleviate pressure on the system.

While the capacity of the system is waiting to be improved, the exchange will continue to close early.

Fujitsu supplies the system to the exchange.
