Relative volume compares how much a stock is trading now vs its usual pace. High RVOL means it’s “in play” — the fuel small-cap movers run on. Enter a ticker to see its volume and dollar volume for the last session, week, month and year, each against an average session.

⚠ 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.
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.
