Mongoose Unified Volatility Index (UVI)
The Mongoose Unified Volatility Index (UVI) combines multiple volatility measures into a single normalized framework, helping traders track the full volatility cycle at a glance.
Methodology
UVI blends the following components:
Bollinger Band Width%
ATR% (Average True Range)
Historical Volatility (close-to-close)
Parkinson Volatility (high-low log range)
Donchian Width%
TR% (True Range percent)
Each input is normalized into a 0–100 scale and weighted. A smoothed EMA acts as a trend filter. Adaptive percentiles define Quiet / Neutral / Active regimes, making UVI responsive across assets and timeframes.
Features
Composite Line (UVI) with dynamic coloring
Green = volatility expanding above EMA
Red = volatility decaying below EMA
EMA Baseline (white) for context
Regime Shading (Quiet, Neutral, Active) based on adaptive percentiles
Expansion Signals (Exp Up / Exp Dn) when volatility crosses EMA around squeeze conditions
Compact Stats Table (top-right) showing UVI, Percentile, Squeeze state, and Regime
How to Use
Quiet → Exp Up: Prime breakout setups. Market energy igniting.
Active → Exp Dn: Trend exhaustion. Manage risk or fade extremes.
Neutral Regime: Mid-volatility, expect chop and tactical swings.
Gradient Fill: Quick bias check — green favors trend trades, red favors patience.
UVI is best used as a volatility state detector to time entries/exits around compressions and expansions, rather than a standalone buy/sell tool.
