Venue scoreboard

A comparable recent view of scale and momentum. Each venue's latest reported day is stated; the comparison is blank unless both seven-day periods are complete.

Recent daily volume by venue

Exact numbers for the most recent ten calendar dates. A tilde marks a still-filling report; an em dash means no figure was published for that venue and date, not zero trading.
