Definitions

In plain terms

Up Volume totals the trading volume assigned to securities classified as advancing, so larger-volume securities contribute more than smaller-volume securities.

Technical

Up Volume is a non-negative market-data field in a stable volume unit, venue scope, and adjustment basis, allocated to the advancing side of a reconciled daily volume partition.

Scope

This concept describes allocated reported volume, not an equal-vote issue count and not buyer-initiated trade classification.

Examples

  • If advancing issues account for 8.2 million reported shares, Up Volume is 8.2 million shares.

Common misconceptions

  • Up Volume is not the number of advancing issues.
