ATK/DEF Session Volume Magnitude & Distance Engine

ATK/DEF - Session Volume Magnitude & Distance Engine is a session-based volume analysis framework designed to observe activity across three defined market sessions: Asian, European, and US.
The script calculates the accumulated volume of each session independently and compares the completed session volumes within the same daily cycle. This creates a relative session-volume structure that allows the volume magnitude of each session to be observed within the same framework.
### Core Framework
* **Three-Session Volume Structure**
Separate volume calculations for the Asian, European, and US sessions.
* **Session Volume Acmulation**
Each session independently accumulates the volume of its confirmed bars.
* **Relative Session Volume Magnitude**
Completed session volume is normalized against the highest completed session volume within the daily cycle.
* **Session Open / Close Structure**
Each session records its opening and closing prices alongside its accumulated volume.
* **Session Volume Visualization**
Relative volume magnitude is displayed through proportional session bars with corresponding volume values.
* **Independent Session Calculation**
Asian, European, and US sessions are calculated separately using their defined session windows and time zones.
### Quantitative Session Analysis
The framework focuses specifically on the relationship between **session activity and session volume magnitude**.
Each session is treated as an independent calculation layer, while the completed sessions are compared within the same daily sequence.
The displayed volume values and relative magnitudes are derived directly from the volume data and calculation rules defined in the script.
### Analytical Purpose
This script is intended for **market observation, quantitative analysis, and -defined decision-making**.
The displayed session volume data and relative volume structure are analytical references only.
