The next holiday in the CME calendar is President’s Day, which occurs Monday, February 18, 2019. A similar halt and resumption will occur then.
As always, be careful trading on and around holidays. Markets can be unexpectedly slow or fast. Also, you don’t want to be in a position, have the market close, and have to place an emergency call with your broker to see if you’re in any danger.
