⚠ End-of-day data — this compares the last full session’s volume to the trailing average, not live intraday RVOL. Real-time intraday relative volume is on the roadmap. RVOL ≥ 2-3× often flags a stock in play; ≥ 5× is extreme.
DUO volume and dollar volume by period
Each period’s average session against the average session in the 252 sessions (one trading year) before it, so a period is never compared with itself. The year row is compared with the year before it.
| Period | Sessions | Shares | Dollar volume (est.) | Per session | vs average session before |

- The multiple compares shares a session, so a price move does not count as extra trading. A week is the last 5 sessions, a month 21 and a year 252.
- Dollar volume is estimated: each session’s shares times its close, added up. Daily bars carry no average traded price, so the true value differs a little.
- DUO’s volume is spiky: its average session over the 252 sessions before the latest (409K shares) is 7.1 times its median session (58K), lifted by a few very heavy days. Against that average, an ordinary day reads far below it.
- Our comparable history for DUO starts Oct 17, 2024. That session opened 21% lower on lighter volume than its recent average, which our adjuster reads as a corporate action such as a spin-off, so earlier sessions are left out rather than compared across it.
- Volume is the consolidated total across US exchanges, end of day, through Oct 30, 2026 (Databento).
