Learn the Book, not just the buttons.
Book Duplex teaches market structure through primitives, tutorials, panel references, and reusable reasoning frameworks.

System Architecture
Documentation built around deterministic transfer
IntroductionStart with the system overview and the Position / Structure / Flow mental model.PrimitivesLearn each metric in isolation before combining them into deterministic reads.TutorialsConvert primitive states into rule-based walkthroughs for real market situations.Visual ReferenceMap every concept back into the Book Duplex interface and panel layout.
Core Principle
Pressure + Friction + Participation
The system does not try to predict price directly. It asks whether structure allows the move, whether participants are funding it, and whether current stretch is aligned with that support.
Continuation
high displacement + strong flow + thin opposing depthTrap
positive flow + negative near-mid structure + flat gravityVacuum
balanced ratio + collapsing depth + elevated curvature
