VIX/VIX3M Term Ratio

What it is

VIX/VIX3M Term Ratio — registry key vix_term_ratio.

Externally-validated volatility term-structure ratio (cleaner form of vix_term_slope); ingested + persisted structure metric, not yet scored.

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

VIX / VIX3M ratio form of the volatility term structure: VIX_close / VIX3M_close. Ratio > 1.0 = backwardation/stress (front above deferred); < 1.0 = contango/normal. Guarded against divide-by-zero. See app/sources/market.py:VIX_Term_Ratio.

Where it surfaces

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

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.
