Definitions
In plain terms
Total Volume counts the reported shares traded within the selected venue or feed scope, using one consistent unit and adjustment policy.
Technical
In the pilot volume contract, Total Volume is positive and must equal Up Volume plus Down Volume plus Unchanged Volume under one series identity and adjustment basis.
Scope
Total Volume is provider- and scope-dependent; figures from different venues, units, or adjustment bases must not be mixed into one series.
Examples
- Eight million up, six million down, and one million unchanged shares reconcile to 15 million Total Volume.
Common misconceptions
- Total Volume from one exchange is not automatically equal to consolidated market volume.
