FOREX.com has expanded its Japanese US-index CFD service to include weekends, giving customers another window to respond to news affecting American equities. A StoneX Securities Japan release posted on 21 October, with a 16 October dateline, identifies US SP500 and US Tech100 as the instruments covered.[4]
Finance Magnates reported the rollout on 21 October. The issuer’s timetable opens Saturday trading at 17:00 Japan time, after a 06:00–17:00 pause; Sunday’s pause is 06:00–07:00. The service spans seven days, with scheduled interruptions.[3][4]
The Japanese entity had already published a disclosure-revision notice on 10 October. It explicitly added explanations covering seven-day trading, trading hours, pricing and associated risks. The announcement date should consequently be distinguished from the earlier documentation change.[1]
Pricing while the reference markets are shut
The revised legal disclosure says StoneX uses alternative price information and its own calculation method during underlying-market closures. Its inputs can include volatility, news and trading conditions. Weekend quotes can differ substantially from prices when the stock and related futures markets reopen.[2]
The same document permits wider weekend spreads and interruptions to pricing or trading. Where the broker cannot maintain reliable quotes, it may restrict the service to closing transactions. These provisions define the practical limits of the additional dealing session.[2]
The local product table lists a 10% margin requirement for individual customers on both indices. At that stated rate, ¥100,000 of exposure requires ¥10,000 of margin before other account considerations. This is an illustration of leverage, rather than the purchase price of underlying shares.[5]
For a trader adjusting wider portfolio exposure, the useful comparison is between an executable weekend quote and the exposure being hedged. A price available within the CFD contract is not a contemporaneous price from an open US equity market. That difference matters most when the underlying market reopens.[2]
