Download script
This script is designed as a visual analysis tool for MetaTrader 4, specifically intended to map out price movements by identifying and plotting structural "reversals" in the market. Instead of standard trend lines, it uses a geometric logic to represent price action as a series of steps or "boxes."
Core Logic and Functionality
1. Movement Identification The script scans historical price data (starting from a user-defined number of previous candles) to determine the direction of the market. It identifies whether the price is trending upward or downward based on the relationship between opening and closing prices.
2. Reversal Detection The logic operates by looking for significant "reversals." A reversal is triggered when the price moves away from its current high or low point by a specific distance (defined by the user as a multiple of "boxes").
- If the market is trending up, the script looks for a drop large enough to qualify as a downward reversal.
- If the market is trending down, the script looks for a rise large enough to qualify as an upward reversal.
3. Geometric Visualization (The "Box" System) Rather than just drawing a line, the script calculates the magnitude of each movement. It determines how many "boxes" tall or deep a move is based on the price difference between the starting point and the reversal point.
- Upward Moves: These are visualized using one specific set of visual bars (histograms) that represent the height gained.
- Downward Moves: These are visualized using a different set of visual bars to distinguish them from upward movements.
- Spacing: The script automatically calculates "empty spaces" or gaps between these figures to ensure the diagram remains proportional and readable on the chart.
4. Dynamic Calculation The tool is designed to be dynamic. Every time a reversal is detected, the script "shifts" its starting point to that new peak or valley. It then continues to monitor the market from that new position until the next significant reversal occurs. This allows the diagram to build itself chronologically as new price data arrives.
User Configuration Summary
The logic relies on three main user-defined variables to customize the look and behavior:
- BoxSize: Defines the unit of measurement for the price height/depth.
- ReversalBox: Determines how much "movement" is required before the script recognizes a change in direction (the sensitivity of the tool).
- Candles: Sets the historical depth the script will look back at to build the initial diagram.
In summary, this script acts as a structural mapper that simplifies complex price fluctuations into a clean, stepped geometric diagram, highlighting significant trend changes based on user-defined price thresholds.
