Fibonacci Zone

The Fibonacci Zone indicator provides a modified Donchian Channel framework that replaces the standard median line with Fibonacci retracement levels to categorize market trends and ranging conditions. By dividing price action into distinct colored zones, it helps traders identify whether an asset is in a bullish, bearish, or neutral state based on its position within the recent price range.

Usage

The Usage section describes how the script can be used, examples should be provided in this section. This tool is primarily used to determine the current trend bias and potential reversal points. Traders can interpret the position of the price relative to the highlighted zones:

• Up Trend Zone (Green): When price trades between the highest border and the 23.6% retracement level, the market is considered to be in a strong bullish state.
• Ranging Zone (Blue): When price fluctuates between the 38.2% and 61.8% retracement levels, it indicates a neutral or sideways market environment.
• Down Trend Zone (Red): When price trades between the lowest border and the 76.4% retracement level, it suggests a strong bearish state.
• Transition Zones (Uncolored/White): The areas between the colored zones act as "in-between" spaces where momentum may be shifting or consolidating.

For example, a trader might look for price to hold above the highest Fibonacci line (0.236) to confirm a breakout, or watch for price to enter the Ranging Zone to scale out of trend-following positions.

Details

The Fibonacci Zone is constructed using a lookback period to determine the highest high and lowest low (the Donchian Channel borders). Instead of a single midpoint, the script calculates four internal Fibonacci levels: 23.6%, 38.2%, 61.8%, and 76.4%.

The script utilizes these levels to create a visual hierarchy of price action. The calculation logic is based on the total range (distance) between the highest and lowest points of the user-defined period. The indicator is most effective when applied to a 20 to 30-period lookback, as this provides enough data to establish significant support and resistance levels while remaining responsive to recent volatility.

Settings

• Calculate for last ## bars: Determines the lookback period (length) used to find the highest high and lowest low. This setting defines the boundaries of the channel. Increasing this value makes the zones wider and more reactive to long-term trends, while decreasing it makes the zones narrower and more sensitive to short-term price movements.

FAQ

How do I interpret the colored zones? The green zone indicates a bullish trend, the red zone indicates a bearish trend, and the blue zone indicates a neutral or ranging market.

What is the recommended lookback period? While the default is set to 21, the script is optimized for a range of 20 to 30 periods to ensure the Fibonacci levels align effectively with market structure.
