SPY put/call ratio

What it is

SPY put/call ratio — registry key spy_pcr.

SPY composite put/call ratio across all expiries.

Source

Source module: market
Data source: live_only

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

How it’s computed

SPY Put/Call open-interest ratio: sum(put_OI) / sum(call_OI) across the Schwab option chain.

Where it surfaces

• API field: signals.spy_pcr 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.

Release cadence
