If the rollover date for ES from 03-23 to 06-23 is in the instrument database as taking place on 03/13/2023, then when the charts are opened on 03/13/2023, a notification window appears to roll over the charts. Further, if the charts were still open since the prior session, if the trader goes into Tools -> Database Management, there is an opportunity to roll over the charts from 03-23 to 06-23. (Should it pop up in this case? It seemingly does not.)
My real question is this - what TIME of day does or should the rollover become listed and cause the pop-up? Is it midnight local time (when the local time date changes)? Or, is it midnight in some specific time zone, such as the time zone of ES's sole exchange (Globex, which is in US CDT)? I assume it is not the exchange time zone because there could be more than one, so it seems it must be midnight local time, but is that the way it should be? Is it "right" that traders in all different time zones get the rollover notice at other times because their date changes at different times? Yet, the sessions all started simultaneously regardless of the time zone the trader was in.
For instance, ES rolled over from 03-23 to 06-23 last Monday. Yet, the instrument default trading times for ES are CME US Index Futures ETH which, for the session date 03/13/2023, begins trading the previous day, 03/12/2023, at 17:00 CDT. Is it "right" that the instrument default trading session is split between two different contracts?
I understand that the rollover dates are just recommendations or suggestions, and I appreciate that different charts might have non-default trading times selected. Yet, I'm wondering, would it not make more sense if the rollover date for ES was 03/13/2023 for the pop-up to occur when the instrument default ETH session began 03/12/2023 at 17:00 because that's the start of the trading date in question?
