The MPI 4-Plane Signal Framework: Trend, GEX, Fundamental, Cascade

A single market signal is a guess. Four independent planes of evidence — Trend (45%), GEX (30%), Fundamental (15%), and Cascade (10%) — governed into a single score is intelligence. This is MPI.

What Is MPI?

MPI — Multi-Plane Intelligence — is SYZYG's composite signal framework. It combines four independent planes of market evidence into a single confidence-weighted intelligence score, governed by fail-closed architecture before any output reaches a decision-maker.

The core insight: no single signal domain captures the full picture of a market opportunity or risk. MPI forces all four planes to testify simultaneously.

"A single market signal is a guess. Four independent planes of evidence, governed into a single score, is intelligence."

The Four Planes

PlaneWeightWhat It Measures
Trend45%Technical price structure, momentum, multi-timeframe alignment, regime trend state
GEX30%Gamma exposure, Vanna pressure, Charm flows, dealer positioning, options flow
Fundamental15%Earnings quality, valuation regime, Form 4 insider activity, macro alignment
Cascade10%Information velocity, social sentiment, narrative acceleration, crowding index

Trend (45%): The dominant plane — sustained price trend is the most durable equity signal. Includes regime-adjusted moving structures, momentum confirmation, and multi-timeframe alignment scoring.

GEX (30%): Options market structure — the forces beneath price invisible in OHLCV data. Captures the structural regime (stabilizer vs. amplifier), Vanna IV-driven flows, Charm expiration pressure, and dealer positioning at key strikes. See Market Structure Intelligence for full detail.

Fundamental (15%): The slowest-moving but most regime-stable plane. Earnings quality, valuation regime classification, Form 4 insider activity from SEC filings, and macro factor alignment.

Cascade (10%): The earliest-warning plane. Information velocity, narrative acceleration, social sentiment crowding, dark pool and options flow anomalies. Highest noise-to-signal ratio, hence lowest weight.

The SYZYG Truth Table

The MPI score alone does not determine the output. The Truth Table maps 8 market regimes × 7 signal configurations → 7 execution classes. This mapping is locked and immutable.

Two invariants are permanently sealed:

  • SYZYGY × SYZYGY = A1 — Maximum conviction long. All planes aligned, positive GEX, trend confirmed.
  • DESYZYGY × DESYZYGY = A2 — Maximum conviction short. All planes aligned short, negative GEX, confirmed downtrend.

Bidirectional Output Gates

  • SYZYGY — Maximum bullish conviction. Full intelligence brief published.
  • SHORT — Maximum bearish conviction. Full bearish brief published.
  • TRADEABLE — Directional conviction below maximum. Brief published with confidence note.
  • AVOID — Structurally unfavorable. Published as avoidance signal.
  • OBSERVE — Insufficient evidence or active plane conflict. Brief suppressed. Suppression logged in RDL.

The Governance Layer

The MPI score and Truth Table verdict are necessary conditions for an output — but not sufficient ones. Before any output is published, the governance layer runs:

Freshness gate: Are all contributing plane inputs within their staleness window? A stale GEX reading forces the output toward OBSERVE or triggers circuit breaker suppression.

Regime validator: Is the active market regime classified and stable? A regime transition in progress triggers a confidence downgrade.

Plane conflict checker: When planes disagree significantly, the governance layer classifies the output as C1 regardless of the composite MPI score.

Every verdict — publish, downgrade, or suppress — is recorded in the Research Decision Ledger. See Circuit Breakers in Governed Intelligence for the full gate sequence.
