This script is designed to create a dynamic visual channel on a trading chart, utilizing Fibonacci principles to help traders identify potential price boundaries. It automatically calculates and plots specific "High" and "Low" price levels based on historical market data.

Core Logic and Functionality

Timeframe Awareness & Synchronization The script is intelligent enough to recognize different timeframes (such as 5-minute, Hourly, Daily, or Weekly charts). It identifies "Delimiter" bars—specific points in time where the market structure resets or shifts based on the timeframe being used. This ensures that the calculations are synchronized correctly with standard trading sessions and calendar cycles.

Dynamic Channel Calculation Instead of relying on a static range, the script looks back at a user-defined period of "Delimiter" bars to analyze price action. It identifies the highest high and lowest low within these sections to establish a price range.

The Center Point: It calculates a central value (TV) by averaging the highest high, the lowest low, and the previous closing price.
Fibonacci Projection: It then projects two boundaries (MaH and MaL) above and below this center point. The distance of these boundaries is determined by a specific Fibonacci ratio (defaulting to 0.786), which provides a mathematical perspective on potential support and resistance zones.

Visual Presentation Modes The script offers two distinct ways to display this information on your chart:

Sectional Display: By default, it draws the channel in segments. This allows you to see how the price boundaries have shifted over time as new "Delimiters" are reached.
Continuous Flow: If the "SetAllBars" option is enabled, the script uses linear interpolation. This means that instead of showing broken segments, it connects the data points smoothly, creating a continuous moving channel across the entire chart history.

Real-Time Updates The logic is designed to update dynamically. As each new candle forms, the script checks if it has hit a new boundary marker. If it has, it recalculates the highs and lows for the new section. Additionally, it contains a specialized function to handle the "Current" bar (the one currently moving in real-time), ensuring that the most recent price data is always accounted for in the displayed levels.

Summary for the User

In simple terms, this tool looks at the market's past moves, finds the extremes (highest and lowest points) over a set period, and draws a "Fibonacci corridor" around them. It helps you visualize where the price might be reacting based on mathematical proportions rather than just guessing where the next wall might be.
