What are the official Globex RTH and ETH times now with the 15 min gone
I have alway set my day session vol profile to cutoff at 3:15 CT and have after hours start at 3:30. What would be the official times now for the Globex sessions?
Can you help answer these questions from other members on NexusFi?
The same as before. The CME opens and closes at the same time as it did for ETH, and assuming you are trading ES from your profile, the stock markets trade at the same time still for the RTH session.
You do not win as a trader, you just get to play again the next day. If that game doesn’t appeal to you then you should not trade. Gary Norden
To slightly expand on it, "regular" trading hours were based on the old pit hours, but the pit has not been in existence for years now. The ruling time period, in the Equities, was always the NYSE stock trading hours, which closes at 4:00 ET (3:00 CT). Volume on the CME Equities takes a nosedive as soon as NY closes. So the relevance of the 15 minutes until 3:15 CT was always fairly low. The "regular" trading hours always just meant the pit hours. Originally there was a difference in the participants after the pit closed, because, well, the pit traders stopped trading when the pit closed for the day. Now there aren't any. So there are no "official" non-pit hours, since it's all non-pit. There used to be a trading pause at 3:15, so it continued to mean something, but now that's gone too.
Since volume will continue to depend on NYSE trading mainly, I think the volume drop-off after the NY close will continue. So if I were trading based on volume profile, I would set it to consider the "session" closed at 3:00 CT, when the volume dries up. But frankly, if you kept it at 3:15 I doubt that it would make any important difference from before, because volume was dying after 3:00 then too, and the stub of 15 minutes wouldn't have mattered much anyway.
To the extent that there is an official session, settlement is at 3:00, no longer at 3:15, and settlement price is computed based on volume weighted average price for the 30 seconds leading up to 3:00. But actually, this is just slicing up the electronic trade day based on staying in step with the NY stock market. The CME day itself ends at 4:00 CT and reopens an hour later at 5:00 CT, as always. "RTH" is more a convenient way to marry up with the stock exchange active hours than anything else.
In the old days, the settlement was at 3:15 CT. However, as has been explained in another recent thread, settlement time was moved up to 3:00 months ago, I believe in September 2020. Settlement time won't matter to most of us day-traders anyway (although, yes, it is an official time when an official price is set), but for what it's worth, it has been the earlier time for almost a year now, probably with most people being none the wiser. (And still counting "RTH" as ending at 3:15. )

Edit: see this thread for discussion on new trading hours, including the current change and the previous change of settlement time:
You should know that starting today (June 28th, 2021), the CME and CBOT will eliminate the 3:15 p.m. 3:30 p.m. Central Time (CT) trading halt on CME Globex which currently exists for certain Equity futures and options contracts.

Of course the daily bar close is the last tick at 4 pm CT, but I guess you mean how the settlement-price is calculated? The settlement-price is the vwap from 2:59:30 pm CT to 3 pm CT
