SMA stack score

What it is

SMA stack score — registry key sma_stack.

Composite breadth structure score; data_only because the breadth_50d/200d entries already carry the band classification.

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

Count of SMAs (20 / 50 / 100 / 200 day) that SPY’s current price is above, 0–4. Higher = stronger trend. See app/sources/market.py:285.

Where it surfaces

• API field: signals.sma_stack_score on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)
• Surface: /signals/history time series
• Surface: /signals/sparklines (UI sparklines)
• Surface: change markers in the rendered report

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.
