SPY SIP settled close

What it is

SPY SIP settled close — registry key spy_sip_close.

Official SIP settled close for SPY (the close.price field from the read-only execution venue MCP quote API, #49) — a cleaner EOD anchor than the last-trade prints elsewhere in the stack. Flag-gated OFF behind an execution-venue spread flag; ships dormant pending a token-reliability soak. Displayed DATA field only — NO scoring band, NOT a health-score component, NOT an alignment input.

Data-pyramid tier

T0 — Raw input. This metric sits at the raw input 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

The official SIP settled close for SPY, read verbatim from the close.price field of the read-only execution venue MCP get_equity_quotes result. No transform. See app/sources/execution venue.py:_quote_close.

Where it surfaces

• API field: signals.spy_sip_close on GET /api/v1/signals/latest
• Surface: daily_signals row (daily-cadence persistence)
• Surface: intraday_signals row (per-cycle snapshot)

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
