About this pageAI generated

This page describes the trading methods for futures and options on the Japan Exchange Group. In regular sessions, contract prices are determined using the Zaraba method based on price and time priority rules. During opening and closing auctions, or after trading resumption, the Itayose method is used to determine prices that maximize traded volume and minimize untraded volume. Market orders are prioritized by acceptance time and matched accordingly. Market orders not executed through the Itayose method become invalid.
