L2 Fibonacci Bands

The L2 Fibonacci Bands indicator is a technical analysis tool that uses Fibonacci expansions of a moving average to identify potential support and resistance levels for trend analysis and reversal identification.

Usage

The L2 Fibonacci Bands can be used to identify extreme price deviations and potential trend exhaustion. Traders typically look for prices to trade outside the extreme bands (Level 3) and then return inside as a signal of a potential reversal or mean reversion.

The slope of the midband provides information regarding the trend's strength and direction; an upward slope suggests a bullish trend, while a downward slope suggests a bearish trend. The bands themselves serve as dynamic support and resistance levels, which can be utilized for setting stop-loss orders or profit targets. For higher probability setups, it is often recommended to align signals from the bands with the trend direction of a higher time frame.

Details

This script is based on the concepts described by Suri Dudella in "Trade Chart Patterns Like the Pros." It calculates bands by applying Fibonacci expansion levels—typically 1.618, 2.618, and 4.236—to the volatility measured by Keltner Channels. Unlike standard Bollinger Bands which use standard deviation, these bands use the Average True Range (ATR) relative to a central moving average to define the expansion zones. This implementation allows users to select between various moving average types (SMA, EMA, WMA, HMA) to serve as the baseline for the expansion.

Settings

• MA Type: Selects the type of Moving Average used as the midband (SMA, EMA, WMA, or HMA).
• MA Length: Determines the lookback period for the central Moving Average calculation.
• Data Source: Specifies the price data used for calculations (e.g., Close, HL2).
• Fibonacci Levels (1, 2, 3): Sets the multipliers for the three sets of upper and lower bands.
• Keltner Channel Multiplier: Adjusts the base volatility factor derived from the ATR.
• Keltner Channel Length: Sets the lookback period for the Average True Range calculation used to scale the bands.

FAQ

How do I use the L2 Fibonacci Bands?

You can use the bands to identify overextended price conditions. When the price crosses outside the Level 3 bands and returns, it may signal a potential reversal toward the midband.

What is the significance of the Fibonacci levels?

The levels 1.618, 2.618, and 4.236 are derived from the Fibonacci sequence and the Golden Ratio, representing common areas where price action tends to react or consolidate in financial markets.
