VWMA Bollinger Bands

The VWMA Bollinger Bands indicator provides a volatility-based envelope using a Volume Weighted Moving Average (VWMA) as the central basis to better reflect market activity compared to standard Simple Moving Averages.

Usage

The Usage section focuses on how the VWMA Bollinger Bands can be applied to identify potential overextended price levels and trend strength. By default, the indicator plots three distinct sets of bands corresponding to one, two, and three standard deviations from the VWMA basis.

• Trend Identification: When price maintains a position between the upper bands, it suggests strong bullish momentum supported by volume.
• Reversal Signals: Price reaching the 3rd standard deviation bands often indicates an overextended market state where a mean reversion toward the VWMA basis might occur.
• Volatility Analysis: The expansion and contraction of the bands provide a visual representation of market volatility, with the VWMA basis ensuring that periods of high volume carry more weight in the calculation.

Details

Unlike traditional Bollinger Bands which use a Simple Moving Average (SMA), this script utilizes a Volume Weighted Moving Average (VWMA). The VWMA emphasizes price action occurring during high-volume periods, making the central basis more reactive to significant market moves.

The implementation calculates standard deviation based on the selected source (defaulting to the opening price) and applies three user-defined multipliers to create the layered band effect. This multi-layered approach allows traders to visualize different "zones" of volatility.

Settings

• Length: The lookback period used for both the VWMA basis and the standard deviation calculation.
• Source: The price data point used for calculations (e.g., Open, High, Low, Close).
• 1st Stdev Mult: The multiplier for the innermost set of bands.
• 2nd Stdev Mult: The multiplier for the middle set of bands.
• 3rd Stdev Mult: The multiplier for the outermost set of bands.

FAQ

How do I access the VWMA Bollinger Bands?

You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.

Why does the indicator use the Open price by default?

The default setting uses the opening price as the source for the VWMA and standard deviation calculations, though this can be adjusted to the closing price or any other source in the settings menu depending on your preference.

What is the advantage of a VWMA basis over an SMA?

A VWMA basis incorporates volume data, meaning price levels with higher trading activity have a greater impact on the average. This can lead to a more accurate representation of "fair value" during volatile sessions compared to a standard SMA.
