Relative Volume in Trade Ideas: how to interpret “stocks in play” ranking¶
Relative Volume answers a simple question: “Is this stock trading more than normal right now?”
Used correctly, it’s one of the best ranking signals for “stocks in play”. Used incorrectly, it becomes a magnet for weird microcap behavior.

What Relative Volume actually measures¶
In plain language: Relative Volume compares current trading activity to a baseline.
That means: - a low-volume stock can show massive Relative Volume on small absolute volume - a high-volume megacap can show modest Relative Volume while still trading huge size
This is why Relative Volume is best used with liquidity constraints.

The “mentor” way to use Relative Volume¶
1) Build a lane first¶
Start with: - price range - liquidity thresholds (ADV / Volume Today / Dollar Volume) - optional float constraint
Related: - Filters that matter - Float / short float
2) Then rank inside the lane¶
Once your universe is reasonable, Relative Volume becomes a great “what’s active” sorter.
3) Pair it with context columns¶
Relative Volume alone doesn’t tell you direction. Pair with: - Gap % - Change from the Open / Close - Volume Today
Related: - Columns that matter
Common traps¶
Trap 1: Microfloats hijack the list¶
Low float names can print wild Relative Volume spikes. If that’s not your niche, constrain float.
Trap 2: Confusing “active” with “tradable”¶
Active can still be illiquid, wide-spread, or news-chaotic. Use liquidity constraints as the gate.
Trap 3: Using Relative Volume without Time of Day¶
If you only trade mornings, don’t rank midday noise. Use: - Time of Day filter
FAQ¶
Is Relative Volume better than Volume Today?¶
They solve different problems. Volume Today is absolute activity today. Relative Volume measures activity relative to normal. Use Volume Today/ADV as gates, and Relative Volume as a ranker.
Why do I see “garbage” at the top of my Relative Volume list?¶
Because Relative Volume can spike on low absolute volume. Add liquidity constraints and (often) a float constraint.
