RiskPicksWhat is Relative Volume?
Relative volume (RVOL) compares how much a stock is trading right now to how much it normally trades. It is expressed as a multiple: an RVOL of 1.0 means average volume, 2.0 means double the average, and 0.5 means half.
The formula is simple: RVOL = Current Volume / Average Volume
Most platforms use a 10-day or 20-day average as the baseline.
Why RVOL matters
Volume is the fuel behind price moves. A stock can break out of a range on low volume and immediately fail, but the same breakout on 3x RVOL has real participation behind it and is far more likely to follow through.
- RVOL above 2.0: something is happening. News, earnings, a catalyst. Worth investigating.
- RVOL 1.0 to 2.0: slightly above average. Could be a setup building, or just noise.
- RVOL below 1.0: below-average participation. Breakouts are unreliable. This is chop territory.
- RVOL above 5.0: extreme. Usually means a major catalyst (earnings surprise, FDA decision, short squeeze). Expect wide spreads and fast moves.
How day traders use RVOL
- Screening: most day traders filter their scanners to only show stocks with RVOL above 1.5 or 2.0. If the volume is not there, the setup is not worth the risk.
- Confirming breakouts: a breakout above resistance is only meaningful if volume is expanding. RVOL rising as price breaks out is a green light.
- Avoiding traps: a stock drifting up on 0.6x RVOL is not a real move. It is low-participation drift that can reverse on a single sell order.
- Time-of-day context: RVOL is most useful in the opening drive. A stock running on 5x RVOL in the first 30 minutes is in play. The same stock at 3x RVOL at midday is less impressive because midday volume is naturally lower.
