Tokyo Stock Exchange accelerates order processing by three times with PRIMERGY platform

"This is the first time I’ve ever experienced the launch of a system without the slightest hint of a problem. The extensive elimination of bugs in upstream processes was achieved as a result of the determination shared by Tokyo Stock Exchange and Fujitsu."

Kenichi Hosokawa Senior Manager, IT Development Tokyo Stock Exchange, Inc.

Tokyo Stock Exchange, Inc. upgrades cash market trading platform ‘arrowhead’ in the quest for world-class reliability with Fujitsu.

The customer

Tokyo Stock Exchange, Inc. (TSE) is one of the world’s top bourses, and it lists around 3,800 brands, including local and overseas equities, ETFs, and REITs. Daily trading value exceeds three trillion yen. The cash market trading system supporting such high transaction volumes is known as ‘arrowhead’. Developed together with Fujitsu under the slogan Challenge “10” msec, arrowhead sought to achieve a response time per order of less than 10 milliseconds, but ultimately achieved two milliseconds.

The challenge

Embarked on a plan to revamp the existing ‘arrowhead’ cash market trading system to increase order processing speeds and ensure stability and security of the increasing number of orders.

The solution

Conducted a review of the arrowhead platform, including its hardware, software and processing logic. Deployed approximately 200 FUJITSU Server PRIMERGY units and the FUJITSU Software Primesoft Server to enable high reliability and high speed.

The benefit

  • The system processes over 100 million orders per day, and at peak times receives as many as 1.4 million orders per minute
  • 90 percent reduction in the number of bugs found in downstream processes
  • Delivers high speed and reliability
  • Achieved a processing speed of 300 microseconds, three times faster than the old system
