Relative Volume
Relative volume (RVOL) compares a session's volume to the stock's own recent average. It normalises for size, judging a mega-cap and a small-cap against their own history, which makes it the standard way to find where unusual activity is happening.

What has to be true for a Relative Volume to trigger
- Session volume well above the stock's own trailing average
- The comparison made against the stock's own baseline, not an absolute threshold
- Sufficient baseline history for the average to be meaningful
How PatternGrade grades it
Higher multiples of the stock's normal volume grade higher.
Every scanner grades its hits A+, A or B from the pattern's own measurable structure. The grading is deterministic — the same chart always produces the same grade. It describes how closely the chart matches the pattern, not how likely anything is to happen; no hit rate or probability is attached to a grade. The reasoning is set out in the methodology.
What a Relative Volume looks like in practice
A stock that normally trades 800,000 shares does 3.4 million by the close, an RVOL of roughly 4.3. The price move that accompanies it is only 2%, which is the interesting part: heavy volume without much price change usually means an unusual amount of stock changed hands at one level, which is either accumulation or distribution depending on where the stock sits in its structure.
How a Relative Volume fails
There is nothing to fail, which is the point: relative volume is a measurement, not a setup. The way it misleads is by being read as directional on its own. High RVOL accompanies breakouts and breakdowns equally, and it spikes on index rebalancing, secondary offerings, expirations and news that has nothing to do with the chart. Volume without structure tells you something happened, not what.
What this pattern is telling you
Relative volume is directionless. Heavy volume accompanies both accumulation and distribution, and the biggest RVOL readings are often news-driven and already priced in.

How to scan for Relative Volume setups
PatternGrade rescans every liquid US stock (~4,500 names) for this pattern after every close and returns the hits as a graded list, with the pattern drawn on each chart, so you review setups rather than hunt for them.

Relative Volume FAQ
What is relative volume (RVOL)?
A stock's current volume divided by its own recent average volume. An RVOL of 3 means it is trading at three times its normal pace.
What is a good RVOL?
Traders commonly treat anything above 2 as notable. It signals activity, not direction, and PatternGrade classifies it as neutral for that reason.
What is a high relative volume?
Conventionally anything above 2 is notable and above 5 is unusual, where 1.0 means the stock is trading at its own average pace. The thresholds are conventions rather than laws, and what counts as unusual varies with the stock, since thinly traded names spike far more easily than large caps.
Is high relative volume bullish?
Not by itself. It says participation is unusual, which amplifies whatever the price action is saying. High volume on a breakout is constructive; the identical reading on a breakdown is not. PatternGrade classifies it as neutral for exactly this reason.
How is relative volume calculated?
Today's volume divided by the average volume over a lookback window, commonly 20 or 50 sessions. The choice of window matters: a short window makes a stock that has been quiet look explosive, and a long one dilutes genuine surges.
What causes volume spikes unrelated to the chart?
Index additions and deletions, quarterly rebalancing, options expiration, secondary offerings, block trades, and scheduled news. These produce large RVOL readings with no technical meaning, which is why volume is best read alongside structure rather than on its own.
Patterns a Relative Volume is mistaken for
- Pocket Pivot
- A pocket pivot compares today's up-volume to recent down-volume within a base. Relative volume compares total volume to its own average with no structural context.
- Distribution Day
- A distribution day requires a price decline on heavier volume. Relative volume is direction-agnostic.
- Volume Dry-Up
- The opposite reading: unusually low relative volume. Same measurement, other tail.
- Consolidation Breakout
- A breakout needs the range as well as the volume. High RVOL is what makes a breakout credible, but it is an input to that pattern rather than a pattern itself.
