Bollinger Bands + Keltner Channel Refurbished

The Bollinger Bands + Keltner Channel Refurbished indicator is a comprehensive volatility tool that merges Bollinger Bands and Keltner Channels into a single interface. It provides traders with a highly customizable framework for analyzing price volatility and trend exhaustion by offering multiple band calculation methods and a vast library of moving average types.

Usage

The script can be used to identify potential breakout or reversal zones by observing how price interacts with the various band levels.

• Switching Indicator Types: Users can toggle between Bollinger Bands (standard deviation-based), Keltner Channels (ATR-based), Parallel Channels, or VWAP Bands.
• Fibonacci Integration: The script includes pre-defined intermediate bands based on Fibonacci values (0.236, 0.5, 0.786, etc.), allowing for more granular analysis of price retracements within the volatility envelopes.
• Moving Average Flexibility: With over 60 MA types available, you can smooth the baseline according to different market conditions. For example, using a "Least Squares Moving Average" for a more responsive trend line or a "Regularized EMA" to filter out noise.
• Dynamic Backgrounds: The background fill can be set to highlight only when price is currently trading within specific channel levels, assisting in visual identification of "detachment" or trend strength.

Details

This indicator consolidates technical concepts from multiple volatility systems:

• Bollinger Bands: Use standard deviation to measure volatility relative to a central moving average. These bands expand and contract based on market activity.
• Keltner Channels: Utilize the Average True Range (ATR) or standard range to calculate envelopes, often providing a smoother channel than Bollinger Bands.
• Custom Baseline: The tool utilizes a specialized Moving Averages Proxy to offer a massive variety of smoothing options including Jurik, ALMA, and Fractal Adaptive Moving Averages, allowing for more precise baseline calculations than standard implementations.

Settings

General Settings

FAQ

How do I access Bollinger Bands + Keltner Channel Refurbished?

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

What is the difference between the BB and KC modes?

Bollinger Bands use standard deviation, which reacts more aggressively to sudden price spikes, while Keltner Channels use ATR, which often results in more consistent channel widths.

Can I use this for trend following?

Yes, by observing the "detachment" of price from the bands or the price position relative to the intermediate Fibonacci levels, you can gauge the strength and persistence of a trend.
