Overview
Book Duplex is a market microstructure learning system built around relative price, orderbook structure, and executed flow. The documentation is organized so a user can move in both directions:
- primitive to tutorial
- tutorial to primitive
- concept to panel
- panel back to concept
Why This Docs System Exists
The objective is not to dump definitions. It is to reduce cognitive load while teaching deterministic reasoning:
- Learn what each primitive means in isolation.
- Learn what pairs of primitives imply together.
- Learn how full-system agreement or conflict changes the read.
- Learn where each signal lives in the interface.
Documentation Layers
Primitives
Primitive pages define the canonical vocabulary of the system:
- Ratio Price
- Displacement
- Depth
- Cumulative Depth
- Log(A/B) Depth
- Net Imbalance
- Centroid
- Trade Flow
- Trade Profile
- Trade Imbalance
- SLS
Tutorials
Tutorial pages turn those primitives into scenario-based reasoning:
- Absorption vs Expansion
- Liquidity Vacuum
- Adverse Selection
- Exhaustion vs Continuation
- Structural Trap
- Momentum Alignment
Visual Reference
Visual reference pages connect metrics to the Book Duplex interface:
Frameworks
Framework pages compress the system into reusable mental shortcuts:
Learning Path
Phase 1: Isolated Primitives
Start with Position, then Structure, then Flow. The goal is to stop translating the metrics and start reading them directly.
Phase 2: Pair Interactions
Read combinations like:
- displacement + depth
- log(A/B) + centroid
- trade profile + depth
- flow + structure
Phase 3: Full-System Reads
Use tutorials like Structural Trap and Momentum Alignment to learn how agreement and conflict propagate across the system.
Deterministic Reading Standard
Every good read should answer:
- Where is price relative to equilibrium?
- What liquidity exists near the execution zone?
- Who is actually participating?
- Do structure and flow agree?
- What would invalidate the read?
