Hi Sierra Support,

My rollover cut-off date and time appear to differ across the various timeframes. I am okay with minor time differences, but for the 3-hour and 90-minute charts, the cut-off time is almost a full day off, which seems unusual.

I have already checked my settings and ensured that all individual chart settings are set to “Date Rule Rollover.” I have also performed a reload and recalculate, but the issue remains.

Below are the cut-off date and times for each timeframe:

4H: 2026-03-16, 09:00

3H: 2026-03-15, 16:00 ****

2H: 2026-03-16, 09:00

90M: 2026-03-15, 17:30 ****

1H: 2026-03-16, 09:00

45M: 2026-03-16, 09:15

30M: 2026-03-16, 08:30

15M: 2026-03-16, 08:00

How are you viewing where the rollover is occurring? Do you have the option for "Chart >> Show Rollover Dates" enabled and viewing that line?

One of the things to keep in mind is that the rollover is going to be at the start of the trading day for the actual rollover date. So if you have reversed session times (i.e. an Evening Session defined where the previous day's evening session starts the trading for the current day) then the rollover will show at that time.

Given this, it also means that the exact time the rollover shows depends on the Session Times. So if you have different Session Times for your charts, this could account for the different rollover times.

And one last item that could affect the time is the setting for "New Bar At Session Start" If this is set to "No" then the exact time may be different due to a new bar not starting at exactly where the new trading day starts.
