Download scriptTechnical Overview and Logic Explanation
This script is designed as a technical analysis tool for the MetaTrader 4 platform. Its primary purpose is to automatically identify specific price結構 (structure) points—specifically "TD Points"—and project potential trend lines, horizontal levels, and profit targets based on those identified points.
The following sections break down the logic into non-technical components:
Core Identification Logic
The script scans historical price data to find significant turning points. Depending on your settings, it uses one of two methods to identify these points:
- Standard TD Points: It looks for specific price relationships where a high or low point is surrounded by lower or higher prices in the preceding and following bars, while also accounting for the closing price of the bar.
- Fractal Method: If enabled, the script switches its logic to identify "Fractals," which are standard self-similar patterns that represent local highs and lows in a price chart.
Trend Analysis & Visual Mapping
Once these high and low points are identified, the script performs the following actions:
- Sequential Tracking: The tool can look back through history to find a sequence of these points (determined by the "Steps" settings). It links the most recent significant point with the one preceding it.
- Trend Line Projection: It draws visible trend lines connecting these high and low points. This helps traders visualize the current trajectory of the market.
- Horizontal Support/Resistance: The script can automatically place horizontal lines at key levels. This is particularly useful for identifying "ceiling" or "floor" prices that the market has interacted with previously.
Target Calculation & Projections
One of the more advanced features of this script is its ability to project future price targets:
- Profit Targets: Based on the angle and distance between two identified TD points, the script calculates potential future areas where the price might stall or reverse.
- Dynamic Levels: It generates three distinct target levels (Target 1, 2, and 3). These are calculated by analyzing the previous price action's "swing" (the distance between local highs and lows) and projecting that expansion forward from the current trend line.
On-Chart Feedback
The script provides multi-layered feedback for the user:
- Visual Markers: It places arrows directly on the chart at every identified point to show exactly where the logic "triggered."
- Data Comments: In the corner of the screen, the script generates a text summary. This summary lists the specific coordinates of the trend points and provides a written breakdown of the calculated profit targets (including the price in pips).
Summary of User Controls
The logic is governed by several toggleable features that allow you to customize the density of information:
- Step Control: Determines how many historical points to track simultaneously.
- Visual Toggles: You can independently turn on or off Trend Lines, Horizontal Lines, and Profit Target projections to keep your chart as clean or as detailed as needed.
- Method Selection: Allows you to choose between the proprietary TD Point logic or standard Fractal geometry.
