The important precautions are listed below.

1. Please refrain from performing rush tests in the Test Environments.
2. Please comply with the requirements regarding order quantity as specified in the Test Guide. If you wish to place orders exceeding these requirements, please specify the test details such as the order quantity, time period, and number of issues to be used, and contact JPX Service Desk (arrowhead/ToSTNeT) <arrowhead@jpx.co.jp>.
3. Regarding order prices, please refrain from placing orders at only one price or placing only market orders. Please place orders at various price levels, as you would in the Production Environment. If a large number of issues display special quotes due to market orders, it may interfere with other participants' test orders. Therefore, we kindly ask that you avoid placing small orders concentrated on only one side (buy or sell). Instead, please place counter orders as well to facilitate executions.
4. Please share the name and contact details of your representative for the test day. We may need to reach out to them should any issues occur during the test.
