This script is designed as a technical analysis tool for the MetaTrader platform, specifically aimed at traders who use Fibonacci-based price levels and time-based market structures. It automatically calculates and plots specific upper and lower price boundaries (MaH and MaL) based on historical price extremes and defined ratios.
The core logic can be broken down into several key functional areas:
Timeframe Awareness and Delimiters
One of the primary features of this tool is its "time awareness." It recognizes standard trading periods (such as 15-minute, Hourly, Daily, Weekly, and Monthly) and identifies specific "delimiter" points within those timeframes. These delimiters act as anchors—logical breaks in the data where the script resets or recalculates its primary price boundaries. This ensures that the analysis is synchronized with standard market sessions rather than just flowing continuously without context.
Dynamic Price Boundary Calculation
The script focuses on identifying significant highs and lows over a specific number of bars (defined by the user). Once these extremes are found, it calculates a central reference point. From this center, it projects two boundaries:
- Upper Boundary (MaH): Calculated using a specific Fibonacci-style ratio relative to the distance between the high and low points.
- Lower Boundary (MaL): Calculated similarly but projected downwards.
These boundaries help traders visualize potential "channels" or zones of interest where price might react or experience resistance and support.
Data Projection and Continuity
The script offers two different ways to display this data on a chart, depending on the user's preference:
- Sectional View: In its default mode, it creates distinct sections of data. It draws the calculated boundaries only for specific segments of the chart, allowing traders to see clear, segmented "blocks" of price action.
- Continuous Flow (Moving Projection): If the user chooses to activate the "SetAllBars" option, the script changes its behavior significantly. Instead of just showing the calculated points, it calculates the linear trajectory between two delimiter points and projects a continuous line across the intervening bars. This fills in the gaps, creating a smooth, connected visual channel for the price.
Real-Time Updating
The logic is designed to remain current as new price data arrives. It constantly checks the most recent candle (the "current" bar) to update the very end of the plotted lines. This ensures that even as the market moves, the most recent upper and lower boundaries are calculated dynamically based on the latest available high, low, and closing prices.
In summary, this tool translates raw price movements into a structured visual channel by identifying key historical extremes at specific time intervals and projecting Fibonacci-inspired boundaries either as distinct segments or as continuous lines.
