Two clocks: the futures and the cash session
US30, NAS100 and US500 are the names most brokers give contracts on the Dow Jones Industrial Average, the Nasdaq-100 and the S&P 500. Two sets of hours matter. The futures on CME Globex trade nearly all week, from Sunday 6:00 p.m. to Friday 5:00 p.m. New York time, and stop for an hour from 5:00 p.m. each day (CME's contract page). The cash session is when the stocks in the index trade on the exchanges, 9:30 a.m. to 4:00 p.m. New York time (NYSE's hours).
A broker's index contract usually trades close to the futures hours, though each broker sets its own and some take a longer break each day. Check your platform once and keep the cash open in mind: many traders plan around 9:30 a.m. in New York, when the stocks start trading.
In the UK
On UK time, the futures week opens on Sunday 22:00 and closes on Friday 21:00. The daily pause is 21:00 to 22:00, and the cash session runs 13:30 to 20:00. The US moves its clocks back on Sunday 1 November. From then the futures open on Sunday 23:00, the pause is 22:00 to 23:00 and the cash session runs 14:30 to 21:00, until the US moves its clocks forward again in March.
Worked example
Example: it is Saturday 31 October, 10:00 UK time, and you want to trade US30. The futures shut on Friday at 21:00. They open again on Sunday 1 November at 23:00, 37 hours later.
