Tokyo Stock Exchange, in collaboration with Fujitsu, has unveiled the upgraded cash equity trading system known as ‘arrowhead4.0’. This latest version marks a significant milestone in the evolution of arrowhead, which first went live in 2010.
The renewal of arrowhead4.0 brings a host of enhancements aimed at improving market convenience and resilience. Notable additions include the introduction of a closing auction session, a Market by Order service for detailed market information, and a bulk order cancellation function for users such as institutional investors.
One key feature of this renewal is the extension of trading hours to maximize trading opportunities for investors. The trading day now concludes at 3:30 p.m., providing an additional 30 minutes for market participants to engage in trading activities.
Moreover, the system’s resilience has been fortified through measures such as triplicating trading data in memory, operating multiple servers in parallel, and enabling swift server switching in case of system failures. These enhancements ensure the secure and uninterrupted operation of the trading system.
The technological backbone of ‘arrowhead4.0’ boasts improved system reliability and processing performance, thanks to Fujitsu’s cutting-edge products and middleware. The incorporation of high-speed technologies and the expertise of seasoned engineers have contributed to the system’s enhanced reliability and stability.
Efforts to boost resilience include the introduction of Fujitsu Software Primesoft Server for ultra high-speed data management, infrastructure upgrades with advanced servers, and the promotion of “loosely-coupled” systems for improved market operations.
In the event of system failures, TSE and Fujitsu have established a unified response team to swiftly address issues and minimize disruptions. These proactive measures ensure the swift recovery and continuity of trading activities.
Looking ahead, TSE and Fujitsu remain committed to advancing the market by adapting to evolving market dynamics and meeting the diverse needs of investors. Their focus is on enhancing market convenience, bolstering international competitiveness, and ensuring safe and secure trading on the Tokyo market.
As two leading entities in the financial and technology sectors, Tokyo Stock Exchange and Fujitsu continue to drive innovation and sustainability in the market landscape, setting the stage for a dynamic and resilient trading environment.
