Relative volume

What it is

Relative volume — registry key screener_rel_vol.

Per-ticker relative volume: today’s volume / 20-day average volume. Values > 1 indicate above-average participation. Stored in screener_features_daily. Feeds archetype scorers (D1 capitulation volume climax, A1 post-earnings overreaction confirmation).

Source

Source module: screener
Data source: computed

Derived metric — produced inside the platform (app/sources/screener.py or equivalent) rather than fetched as a raw upstream value. See the How it's computed section below for the formula.

How it’s computed

volume_today / mean(volume, trailing 20 days excluding today). NULL when fewer than 21 rows of volume data or volume is zero/missing.

Where it surfaces

• API field: screener.features.rel_vol on GET /api/v1/signals/latest

Health-score / alignment role

Data carrier — no implication, no health-score contribution.

Persisted for downstream consumers (sparklines, base-rate matcher, calibration substrate) but does not classify into BULLISH / NEUTRAL / BEARISH and does not contribute to the 0-100 health score.
