Tokyo Stock Exchange (TSE) will increase the
frequency of distribution for the indices which it calculates, such as TOPIX, to
1 sec., and, additionally, launch a new High-Speed Index Dissemination Service
provided at the millisecond level.
With the advancement of financial technology and the spread of new trading
methods, such as algorithmic trading, the market environment is evolving. In
order to respond to these developments, TSE introduced a "co-location
service" in May 2009 and launched the next-generation trading system
"arrowhead" on January 4th of this year. Continuing this trend, the
high-speed service will also be introduced as a further improvement to TSE's
services.
Furthermore, the High-Speed Index Dissemination Service is aimed at calculating
and distributing the target indices at the millisecond-level (1 millisecond is
1/1000th of a second), whenever a price to be used in such indices occurs. In
addition to the indices calculated from contract prices, etc. of their component
issues, new indices will be calculated and disseminated utilizing best bid
quotes and best offer quotes. The use of quotes in calculation and the
high-speed of dissemination serve to put this service on the leading-edge.
