ATK / DEF Multi-Session Transition Heatmap

ATK / DEF — Multi-Session Transition Heatmap is a multi-session market analysis framework built around three major market sessions:
**Asia · Europe · America**
The indicator dynamically evaluates each session through a multi-factor calculation model and generates an independent **Composite** evaluation for each market session.
The framework combines multiple calculated dimensions, including:
**Strength · Push · Risk · Liquidity**
These components are normalized and aggregated into a structured session evaluation, creating a three-tier **Transition Heatmap** that visually represents the calculated state of each session.
## Core Features
* Three-session framework: Asia / Europe / America
* Dynamic session-based calculation
* Multi-factor session evaluation
* Independent Composite evaluation for each session
* Strength / Push / Risk / Liquidity dimensions
* 0–100 normalized calculation scale
* Three-tier Transition Heatmap visualization
* Configurable session definitions and timezone
* Adjustable normalization period
* Dynamic tier width based on Composite evaluation
## Analysis Framework
The distinctive feature of ATK / DEF is its **state-based composite structure**.
Rather than relying on a single calculation, multiple session factors are processed and combined into a unified Composite evaluation for each market session.
The resulting structure provides a compact visual representation of the calculated conditions across:
**Asia → Europe → America**
## Analytical Use
ATK / DEF is designed **soly for market observation and analysis**.
All displayed values and Composite evaluations are generated from the indicator's internal calculations and user-defined parameters. They represent calculation-based analytical references and do not constitute definitive measurements of market intent,activity, , or future market behavior.
This indicator does not provide trting guance, predictions, or rios.
