Thuan VSA Ultra [Price & Volume]

Overview
The Thuan VSA Ultra is a comprehensive technical analysis tool designed to identify market accumulation and distribution phases based on the core principles of Richard Wyckoff and Volume Spread Analysis (VSA). Unlike standard indicators that rely on lagging oscillators like RSI, this script focuses on the raw interaction between Price Action and Institutional Volume.
The indicator automatically detects key market milestones such as Selling Climax (SC), Buying Climax (BC), and Automatic Rallies (AR), helping traders visualize the "Trading Range" where Smart Money operates.
Key Features
Volume-Confirmed Climax Detection: Identifies SC and BC points only when a significant Volume Spike occurs (customizable threshold), filtering out market noise.
Dynamic Trading Range (TR): Automatically plots Accumulation Zones (Green) and Distribution Zones (Red) once the initial phase is established.
Smart Liquidity Sweeps: Specialized logic to detect Springs and Upthrusts (UTAD)—the classic "traps" set by institutional players before a major trend reversal.
Pivot-Based Logic: Uses high-precision pivot points to mark structural highs and lows, ensuring labels are placed at mathematically significant levels.
How to Trade with this Indicator
Accumulation Phase (Bullish Bias):
Look for the SC (Selling Climax) label accompanied by high volume.
Wait for the AR (Automatic Rally) to define the upper boundary of the range.
The best entry often occurs at a SPRING signal, where price sweeps below the SC low and quickly recovers.
Distribution Phase (Bearish Bias):
Identify the BC (Buying Climax) at the top of a trend.
Monitor the AR (Automatic Reaction) to set the lower boundary.
Watch for a UTAD (Upthrust) above the BC high as a potential short-selling opportunity.
Sign of Strength/Weakness (SOS/SOW):
A breakout above the Green Zone or below the Red Zone suggests the start of a new trending phase.
Settings & Customization
Pivot Length: Adjust the sensitivity of structural detection (Default: 5).
Volume Spike Threshold: Define how many times the current volume must exceed the SMA to be considered "Institutional" (Default: 1.5x).
Lookback Period: The window used to calculate average volume.
