Monday, May 28 is Memorial Day. Markets like the E-mini S&P 500 will observe different hours, so be sure to check the official CME calendar. On Memorial Day, the E-mini will halt at 1 p.m. ET and reopen the same day at 6 p.m. ET. Essentially, the E-mini shuts down for about five hours. The market halt also applies to the CME’s equity, interest rate, FX, NYMEX & COMEX products (markets). If you’re not in US/Eastern time, remember to convert these US/Eastern time hours to your time zone’s equivalent.
After Memorial Day, the next major trading holiday is Independence Day (July 4, 2018). We will post those details closer to that date.
Watch out for potentially slower than usual markets on Friday, May 25. Often times, we see slower activity on the Friday before three day weekends. And yes, you should still be trading the ES 06-18 contract until the rollover date in June 2018.
