There is a growing demand among investors for trades without pre-trade transparency in order to minimize market impact, and a number of brokers provide solution by reporting the pair of buy and sell orders to ToSTNet for a TSE off-auction trade.
Kai-X aggregates such orders from various brokers and finds the other side of order. When Kai-X finds a match, it immediately sends an indication of the match to the corresponding broker and at the same time sends the orders to ToSTNet for TSE off-auction execution.
For the brokers using Kai-X, they can easily source additional liquidity from the other brokers without liquidity sharing arrangement. For those brokers wishing to save development/maintenance costs, Kai-X could be viewed as an outsourced facility.
TSE-listed common stocks, ETFs and REITs (excluding foreign stocks and some foreign ETFs).
The same units used in TSE are applied.
Kai-X is an intermediary service in which Chi-X Japan receives and matches orders from participants systematically. Orders are continuously matched, and after a match Kai-X notifies the respective participant with information necessary for the participant to report to ToSTNeT with minimal delay.
The following 3 price points are available for orders. Limit price can be set.
