Sorry if this is obvious but on the CME Globex site the hours are listed as 17:00-15:15 and 15:30-16:30 What are the weekly and weekend trading hours for the ES mini futures?
To recap in Central Standard Time: When you start trading at 5 pm on Sunday, you trade until 3:15 pm Monday , then closed til 3:30 (15 min), then trade for one hour til 4:30 , closed for 30 min til 5:00 pm, then reopens and trades til 3:15 pm next day when process repeats til 3:15 pm on Friday at which time it closes til 5 pm on Sunday. At least that it how it works on my computer with IB. Also confusing as to how they label the days. Stosh
