Should an asterisk be next to incomplete data? i.e. CBOE data feed behind paywall starting Friday 6/30/2023. So invalidates comparing previous data to data after 6/29/2023.

there is a whole lot more than just that missing, this is footnote 2 on chartexchange
“2 Not every exchange reports the daily short volume free of charge (or at all), so total volume in this table will be less than the daily volume at the top of the page. Volume for trades during regular trading hours.”
so it is the best possible representation of the data available
