Nikkei derivatives trade glitch fixed

Bloomberg

Trading of Nikkei 225 stock average options and futures in Japan resumed trading at 2:10 p.m. in Osaka after being halted Monday morning due to a system error, the first outage since the city’s bourse adopted Nasdaq OMX Group Inc. technology for derivatives trading in 2011.

“We are still unclear on the reasons for the error,” Japan Exchange Group Inc. spokeswoman Miwa Aonuma said. The failure began with Nikkei 225 options stopping at 10:20 a.m. and spread to futures at 10:51 a.m., with trades of individual stock options not affected, she said.

The trading system that failed Monday, known as J-Gate, uses technology from Nasdaq OMX. Japan Exchange Group, formed by the merger of Osaka Securities Exchange Co. and Tokyo Stock Exchange Group Inc., plans to adopt J-Gate for all derivatives trades by next March, it said in October.

The Tokyo Stock Exchange in August had its second major system error in seven months, halting derivatives trading for about 95 minutes, cutting equity volumes, driving government bonds lower and sending futures traders to Osaka.
