CO(Cooling-Off Period) - Enhanced Circuit Breaker of Foreign Index Futures or FX Futures or commodity futures and options is triggered. After the 10 minutes Cooling-Off Period, the price limits of all months contracts will be expanded to 2nd (or 3rd) level. You can trade Nikkei through Topix, SGX, CME. Nikkei can be denominated in yen, or US$. I do day trading various futures. I avoid trading nikkei totally due to its very small day range.

Hi, I'm just wondering why the TOPIX futures (full size) volume on the JPX is so little compared to the Nikkei 225 Mini. It seems to be pretty good for scalping for 2 ticks or so, and the commissions are cheap. Access more of Japan's top stocks in one trade TOPIX futures (Bloomberg: TPYA <Index>) are now available to trade on CME Globex, representing the first major listing of yen-denominated TOPIX futures outside of Japan. The All Futures page lists all open contracts for the commodity you've selected. Intraday futures prices are delayed 10 minutes, per exchange rules, and are listed in CST. Overnight (Globex) prices are shown on the page through to 7pm CST, after which time it will list only trading activity for the next day.
