Effective Sunday, September 12, 2010, the electronic trading hours for the Nikkei 225 Yen-denominated futures will be expanded to give market participants worldwide nearly 24-hour access to the benchmark contracts listed at CME and traded on the CME Globex platform.
With this expansion, market participants will be able to trade the futures contracts while the Japanese equity market is open. Previously, the futures contracts traded at CME Group were available only while the Japanese equity market was closed.
Under the expanded hours, trading on CME Globex will begin Sundays at 17:00 through 15:15 CT the following day, with trading Monday–Friday from 15:30 through 15:15 the next day (closing at 15:15 Friday, with a daily maintenance shutdown between 16:30-17:00).
The expanded trading hours were added as part of the licensing agreement extension between CME and Nikkei Inc.
