The Mathematical Engine

Differential Curvature & Turning Angle Architecture

Traditional scalar crossing rules fail during midday consolidation because oscillating indicator noise triggers false breakouts. Model 2 evaluates continuous multi-point curvature rather than single-point thresholds.

STAGE 01 · REGIME GATE

Morning Momentum Filter

Requires the Pulse indicator to cross above +40 prior to 10:30 AM, ensuring an underlying structural trend exists before searching for pullbacks.

STAGE 02 · TEMPORAL WINDOW

Midday Equilibrium Band

Evaluates bars between 10:30 AM and 01:30 PM. Locates a causal trough vertex residing inside the zero-reversion band: -20 ≤ Pulse ≤ +15.

STAGE 03 · VECTOR DEFLECTION

Angular Deflection ≥ 35°

Computes pre-trough descent slope ($pre\_dy < -0.15$) and post-trough ascent slope ($post\_dy > 0.10$). Total angular turn $\Delta heta$ must exceed 35.0°.

Visual Anatomy: Parabolic / Asymmetric Hook Geometry

Zero Baseline (0.0) Equilibrium Zone [-20 to +15] θ_in (Descent slope < -0.15) θ_out (Ascent slope > +0.10) Trough Vertex (κ > 0.05) ENTRY TRIGGER: Pulse > Smoothed (Δθ ≥ 35°)
Risk-Reward Asymmetry

MFE / MAE Excursion Profiling

Analyzing maximum upside opportunity against adverse drawdown proves that the geometric hook delivers an extraordinarily favorable asymmetric distribution.
