Dual Bollinger Bands

Dual Bollinger Bands

Dual Bollinger Bands is an advanced volatility-based indicator that plots two independent Bollinger Band sets on the same chart, allowing traders to analyze price behavior from multiple perspectives simultaneously.

Unlike standard Bollinger Bands, this indicator lets you configure each band set separately, making it especially useful for identifying asymmetric volatility, price compression/expansion zones, and dynamic support and resistance levels.

Key Features

Two fully independent Bollinger Bands

Each band has its own length, standard deviation multiplier, and moving average type.

Different price sources

BB1 can be calculated using High prices, while BB2 can use Low prices (or any source you choose), enabling a directional volatility envelope.

Custom Moving Average types

Choose between SMA, EMA, SMMA (RMA), WMA, or VWMA for each Bollinger basis.

Offset capability

Optional forward/backward offset allows visual projection or historical alignment analysis.

Clear visual separation

Each Bollinger set uses distinct colors and shaded areas for easy interpretation.

Overlay on price chart

Designed to work directly on the main chart for contextual market analysis.

How to Use

Volatility Analysis

Observe expansions and contractions between the two Bollinger sets to identify volatility regimes.

Dynamic Support & Resistance

Upper and lower bands can act as adaptive levels where price may react or revert.

Trend Context

When price consistently respects one side of a band set, it may indicate directional strength.

Mean Reversion & Breakout Zones

Convergence between bands may suggest compression, while rapid divergence can signal breakout conditions.

Best Use Cases

Intraday and swing trading

Volatility-based strategies

Trend-following or mean-reversion systems

Crypto, Forex, Indices, and Equities

Notes

This indicator does not generate signals by itself. It is designed to be used as a contextual volatility and structure tool, ideally combined with price action, market structure, or higher-level trading frameworks.
