Mongoose Unified Volatility Index (UVI)

87
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

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.
