⚠ 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.
SHY 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.

- 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.
- Volume is the consolidated total across US exchanges, end of day, through Oct 23, 2026 (Databento).
