障害当日に取引再開　終日売買停止・再発防止へ中間報告―東証

　東京証券取引所は２１日、１０月に発生したシステム障害と終日の株式売買停止を受けて証券会社などと設置した「再発防止策検討協議会」を開き、中間報告を取りまとめた。障害発生当日に「短時間でも売買を再開する」と明記したのが柱で、証券会社から事前に受け付けた注文は、売買再開に向けて必要な場合に取り消すとした。
　東証と親会社の日本取引所グループ（ＪＰＸ）は金融庁から業務改善命令を受けており、取引再開ルールを整備することで再発を防ぐ。来年３月末をめどに最終報告を策定する。（2020/12/21-20:28）

The Tokyo Stock Exchange said Monday that it plans to resume trading on the day of a system failure even for a short time.
   The plan was included in an interim report compiled by a task force the TSE created with brokerage houses and others in the wake of the system glitch and full-day trading suspension on the exchange on Oct. 1. The panel plans to draw up a final report at the end of March next year.
   The TSE and its parent, Japan Exchange Group Inc. have received a business improvement order from the Financial Services Agency over the glitch, and are working to prevent a similar problem from happening again.
   The interim report said the TSE will show its intent to resume trading from 2:45 p.m., 15 minutes before the closing bell on normal market days, if orders can be accepted by 2:30 p.m. The TSE will also consider the possibility of extending trading hours beyond 3 p.m.
   In case a glitch occurs in the future, the TSE will ask all securities companies, when the restart of trading becomes likely, whether they can rejoin trading. The market will be reopened if 50 pct or more of securities firms and 30 pct of more of individual investors in terms of trading volume are able to rejoin, the report said.
