Because of network problems, all securities trading was suspended, so when key economic data were released, the stock trading of thousands of companies was frozen. Stock subscription was also rejected. Also affected are derivative transactions, including futures trading on Osaka Stock Exchange, which do not seem to have systemic problems. As a result, at 9 am Osaka time, the Nikkei 225 index futures rose by 0.6%. In fact, there have been securities trading problems in Japan before, mainly due to system errors. In 20 12 years, the standby system failure led to the suspension of derivatives trading at least twice. In addition, in June, 5438+October, 2006 10, the Tokyo Stock Exchange suspended trading due to the surge of instructions caused by the investigation of Livedoor company, which led to the overload operation of the computer system of the Tokyo Stock Exchange. ?
As for when the suspended trading will resume, the operator of the Tokyo Stock Exchange, Japan Stock Exchange Group, has expressed uncertainty. This time, because of the system network problems, the securities trading could not be carried out normally. All securities trading can only be suspended. This will be a huge challenge for Japan. It has also become the biggest fault in history. ?
This time, the fault spread to Sapporo, Nagoya and Fukuoka stock exchanges, which also used Zhengdong system, and all stock trading stopped all day. Fortunately, futures trading in the Sapporo, Nagoya and Fukuoka stock exchanges of Zhengdong System can still be carried out normally. Not affected by this failure. Finally, I hope that Japan will solve the problem as soon as possible and resume normal securities trading.
