Fibonacci Bollinger Bands

The Fibonacci Bollinger Bands indicator provides a multi-layered volatility envelope by combining traditional Bollinger Band logic with Fibonacci retracement levels to identify potential support, resistance, and exhaustion zones.

Usage

The indicator can be used to visualize various levels of price deviation from a central volume-weighted moving average (VWMA). Unlike standard Bollinger Bands that typically use a single standard deviation, this tool plots multiple bands based on Fibonacci ratios (0.236, 0.382, 0.5, 0.618, 0.764, and 1.0).

• Trend Identification: When price remains consistently above the basis (middle line), the market is in an uptrend. Conversely, staying below the basis suggests a downtrend.
• Reversal Zones: The outer bands (especially the 0.618 and 1.0 levels) often act as dynamic resistance or support. A price touch or pierce of the 1.0 multiplier band (red for upper, green for lower) may indicate an overextended market prone to a pullback.
• Volatility Squeeze: When the bands contract significantly, it indicates a period of low volatility, often preceding a major breakout.

Details

The script utilizes a Volume Weighted Moving Average (VWMA) as the "Basis" line, which accounts for trading volume to provide a more responsive mean than a simple moving average. The "Deviation" is calculated using the standard deviation of the source price over a specified length, multiplied by a user-defined multiplier.

The specific Fibonacci ratios applied to this deviation are:

• 0.236, 0.382, 0.5 (Gray lines)
• 0.618 (Orange line, often referred to as the Golden Ratio)
• 0.764 (Gray line)
• 1.0 (Solid Red/Green lines representing the full volatility range)

Settings

• Length: The lookback period used to calculate the VWMA and the standard deviation.
• Source: The price data point used for calculations (default is HLC3).
• Multiplier: A global coefficient that scales the width of all plotted Fibonacci bands simultaneously.

FAQ

How do I interpret the colored lines?

The orange lines represent the 0.618 Fibonacci level, often used to identify significant retracement or extension targets. The thickest outer lines (1.0) represent the maximum volatility range defined by your settings.

What is the advantage of using VWMA for the basis?

The Volume Weighted Moving Average gives more weight to price action occurring during high-volume periods, making the central basis more reflective of institutional interest and true market value compared to a standard SMA.
