SMA stack label

What it is

SMA stack label — registry key sma_stack_label.

Categorical SMA-stack classification string; underlying sma_stack_score carries the bands.

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: market
Data source: computed

Derived metric — produced inside the platform (app/sources/market.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

Human-readable label for sma_stack — ‘Above all 4 SMAs (full-stack long)’, ‘Below all 4 SMAs (full-stack short)’, or ‘Above {Xd} SMA(s) · below {Yd}’. See app/sources/market.py:303.

Where it surfaces

• API field: signals.sma_stack_label on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)

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.
