[quote=carlsbadworker]I am pretty sure that US stock future opens at Sunday night. The New York market maybe is closed but people can trade US future from Asian or European market.
Next time, check here on Sunday night: http://www.bloomberg.com/markets/stocks/futures/%5B/quote%5D
Yes they do, normally. More like Sunday afternoon. But they closed Monday an hour after the cash close, until 4 AM west coast time for the new year’s day holiday. Forex trading resumed yesterday afternoon, before Asian markets opened.
