After the close of futures trading at 3:15 on Friday afternoon, the futures do not trade again until 5:30 Sunday afternoon. All times are Central Time since the CME is in Chicago.
Any changes in the futures quotes between those times are erroneous.
Hope that helps.

I edit: I think the futures are down hard because the reality of war is at hand - as I have said here many times, war is not bullish.
