This Month's Pivot Points

Here is the chart I posted January 3. As you can see the pivot points are quite different from  the points on the chart last night, and they aren't supposed to be, The Stockcharts chart school article on pivots points is pretty clear about how they are calculated: on the daily chart, the prior month's data is used, and once it is calculated, it does not change until the current month ends. I will try to figure out what happened here.
