Hi guys, I was trying to understand how the ES work and I read that its trading hours close from 15:15 to 15:30 and from 16:30 to 17:00 CT, however when I looked into a 1min chart I still saw that it was traded between 21:15 and 21:30 BST time (which correspond to 15:15-15:30 CST). Can you have a look at the attachment and let me know if it's normal that the ES is still traded during those maintenance hours? or I am checking something incorrectly? Cheers.
