Live net dealer gamma (options-analytics)

What it is

Live net dealer gamma (options-analytics) — registry key fa_live_net_gex.

Live (flow-adjusted) aggregate net dealer gamma exposure for SPY from the live options-analytics dealer-risk archive, in billions. Distinct from the dealer-gamma-analytics GEX column (Law 3). Participates in the live-driven gamma alignment category as the primary leg (classified on its own sign scale), but stays out of the health-score and band surfaces — captured forward as a hedge, not a scored dial until forward-graded.

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.

How it’s computed

Where it surfaces

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

Release cadence

• Publishes: intraday

Live options-analytics dealer-risk endpoint, polled on the full profile (4x/trading day).
