How this page is made

A scheduled job builds this page once a day at 00:40 UTC, after the 00:10 UTC daily venue snapshot. The job reads stored data only. Each change compares the newest stored reading with the reading from about one day earlier.

Trading cost is the taker fee plus half the spread plus price impact for one market buy. Funding shows the rate in the venue's own interval. A dash (—) means that no earlier reading is available. The digest never replaces a missing value with zero.
