RSI-14 (per-ticker)

What it is

RSI-14 (per-ticker) — registry key screener_rsi_14.

Per-ticker 14-period RSI using Wilder exponential smoothing (alpha=1/14). Stored in screener_features_daily, not daily_signals. Feeds archetype scorers — distinct from the macro RSI already in the platform (spy_rsi in daily_signals).

Data-pyramid tier

T1 — Signal. This metric sits at the signal layer of the platform’s six-tier data pyramid (T0 raw inputs → T5 actionable read). The tier reflects how far the value is from a raw measurement — not how strongly it is validated. Abstraction and validation are separate axes: a higher tier is not a claim of stronger evidence.

Horizon & validation

No validated skill horizon is on file for this metric — read it as context / a data carrier, not a validated edge. Stamps are added only when a gated research verdict lands.

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

RSI = 100 - 100/(1 + avg_gain/avg_loss) where gains and losses are smoothed with Wilder EMA (ewm com=13). NULL when fewer than 15 rows.

Where it surfaces

• API field: screener.features.rsi_14 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.
