Double Bollinger Bands strategy

The Double Bollinger Bands strategy indicator provides a visual framework for identifying trend-following trade setups based on price interactions with volatility bands. It aims to help traders capture strong market movements by highlighting specific breakout and trend-holding zones.

Usage

The tool is primarily used to identify entries and exits based on price closes relative to the Bollinger Bands:

• Long Setups: A long opportunity is signaled when a candlestick closes above the upper Bollinger Band. In this scenario, the background/fill turns green, indicating a bullish momentum phase.
• Short Setups: A short opportunity is signaled when a candlestick closes below the lower Bollinger Band. The background/fill turns red, indicating a bearish momentum phase.
• Trend Management: Traders can use the color fills to manage existing positions. A common approach is to hold a long position as long as the price remains above the basis (middle line) or within the upper band zone, and hold a short position as long as the price remains below the basis or within the lower band zone.

Details

The Double Bollinger Bands strategy utilizes standard deviation and a simple moving average (SMA) to create dynamic support and resistance zones. Unlike standard Bollinger Bands which often use a multiplier of 2.0, this script defaults to a 1.0 multiplier to more aggressively identify "buy" and "sell" zones where price begins to trend away from the mean. The visual fills between the basis and the bands change color dynamically based on whether the price is currently trading in a bullish or bearish breakout state, providing an intuitive way to track trend persistence.

Settings

• Length: The lookback period used for the Simple Moving Average (basis) and the Standard Deviation calculation.
• Source: The price data point used for calculations (e.g., Close, Open, High, Low).
• Multiplier: The value used to multiply the standard deviation, determining the width of the bands.
