Update : Sep. 04, 2012
"arrowhead" is the next generation trading system, which combines low latency, high reliability, and scalability, was launched on Monday, January 4, 2010. This system will handle the auction trading of all cash products such as stocks and CBs.
Constantly ensure twice the maximum processing capacity of actual conditions. In concrete terms, when the maximum system processing value under actual conditions for a whole day or the number of orders per minute reaches 1/2 of the predetermined system threshold value, scale up accordingly to secure twice the maximum actual processing value. Accommodate within a week in the case where such scalability criteria were exceeded.
The previous system conducted matching once every few seconds; matching in arrowhead is immediate.
Sufficient arrangements have been made for capacity based on the market estimate for arrowhead calculated based on the current amount of orders, etc.
Various trading rules were revised with the launch of arrowhead. For details, please refer to "Revision of Trading Rules".
