売買システム再立ち上げによる売買再開 | 日本取引所グループ

This page outlines the rules and procedures for trading resumption following the Tokyo Stock Exchange's trading system failure on October 1, 2020. When the system restarts, execution confirmations are generally valid, but orders must be resubmitted by trading participants. The document details how to handle commissioned orders, partially executed orders, reference prices, and short-sale price restrictions. Market information after restart reflects only post-restart trading, with full-day data released after close. Specific guidance addresses the handling of orders, price continuity, and regulatory considerations during system restart procedures.
