１． About trading system

JASDAQ system introduced in 1991 was developed as the infrastructure for the auction trading system and information transmission.

In parallel with the adoption of the market maker system in 1998 for enhancement of liquidity, the market make trading system was newly added to the entire JASDAQ system. The system was developed as the first trading system using an open server in the securities market.

In 2003, API (Application Program Interface) system was started as a breakthrough in the securities market of Japan and as the completely new system pioneering the market as an open system of the twenty-first century.
