Breadth (200d)

What it is

Breadth (200d) — registry key breadth_200d.

Breadth scoring uses 50d only; 200d provides longer-term context for the composite breadth_signal.

Source

Source module: breadth
Data source: back_fillable

Fetched directly from app/sources/breadth.py; see source code for the upstream API call and any provider-specific handling.

How it’s computed

Percent of S&P 500 constituents whose latest close is above their own 200-day SMA: count(close > sma200) / count(valid) × 100. See app/sources/breadth.py:84.

Where it surfaces

• API field: signals.pct_above_200sma 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

Bands / thresholds

Classifier direction: higher_is_better.

Health-score / alignment role

Display-only — has bands for surface labeling but does not contribute to the health score (scoring is handled by a companion metric).
