So the change from the standard hours was that the exchange closed at 12:00:00 on Monday 17th February 2025. When it reopened at 17:00:00 that evening the regular hours were followed. Note that these times are in Central US time.

This is what you will see in Sierra Chart as long as your Session Times are set to cover the full 24 hours of trading. If your Session Times are not set to cover the full 24 hours, then you may be missing information.
