Fibonacci levels

The Fibonacci levels indicator provides a dynamic volatility-based envelope system that uses Fibonacci ratios and standard deviation to identify potential support and resistance zones. It functions as a specialized variation of Bollinger Bands, offering multiple tiers of price expansion and contraction levels calculated relative to a central exponential moving average.

Usage

The Usage section describes how the script can be used, examples should be provided in this section. This section also focuses on how main settings affect the indicator interpretation and output.

• Trend Identification: The central Mid Line (EMA) serves as the primary trend filter. When price remains consistently above the Mid Line, the trend is considered bullish; when below, it is considered bearish.
• Volatility Envelopes: The script plots six levels above and six levels below the Mid Line. These levels expand and contract based on market volatility (Standard Deviation).
• Support and Resistance: Traders can use the outer bands (Levels 4, 5, and 6) as potential exhaustion points or reversal zones, while the inner bands (Levels 1, 2, and 3) often act as minor support or resistance during trending markets.
• Mean Reversion: Significant deviations away from the Mid Line toward the outer Fibonacci levels may signal overextended market conditions, suggesting a potential return to the mean.

Details

The indicator is constructed using a modified standard deviation approach. Rather than using a static multiplier, the script calculates a "max multiplier" based on the distance between the bar's body (top of candle or bottom of candle) and the Mid Line, normalized by the current standard deviation.

Key Fibonacci-related constants used in the calculation include:

• 0.38196601
• 1.38196601
• 1.61803399

The script utilizes an "Effective Close," which selects the top of the candle body in bullish bars and the bottom of the candle body in bearish bars, to calculate the base EMA and Standard Deviation. This focus on candle bodies rather than wicks aims to reduce noise from erratic price spikes. This script is a refactored version of the original work by @raymond_red_reddington.

Settings

• 50 MA: A secondary period setting (retained for compatibility with original logic).
• 100 MA: Determines the lookback period for the central Exponential Moving Average (EMA) and the Standard Deviation calculation used for the bands. Increasing this value results in smoother, slower-reacting levels.

FAQ

How do I interpret the different levels? The levels represent various degrees of price deviation. Inner levels (1-3) represent standard volatility fluctuations, while outer levels (4-6) represent extreme price extensions where reversals or significant pullbacks are more likely to occur.

How does this differ from standard Bollinger Bands? Unlike standard Bollinger Bands which typically use a simple moving average and a static multiplier of 2, this indicator uses an EMA, an "Effective Close" calculation based on candle bodies, and dynamic multipliers derived from Fibonacci ratios.
