Ind-TD-DeMark-3-1_v2

This script is designed for the MetaTrader platform to provide visual market analysis by identifying specific price structures known as "TD Points." It helps traders visualize market trends and potential reversal levels by automatically plotting geometric data on their charts.

Core Functionality

The primary purpose of this tool is to scan historical price data to identify significant highs and lows. Rather than just looking at every peak, it uses a specific logic to find "TD Points," which are key structural anchors in price action.

Depending on your settings, the script can identify these points using one of two methods:

  • Standard TD Points: Uses specific price movements (comparing current highs/lows against previous bars and closing prices) to determine a significant point.
  • Fractal Method: An alternative mode that uses "fractal" patterns—specific shapes where a high or low point is surrounded by lower or higher points on either side.

Visual Elements and Analysis

Once the script identifies these key structural points, it performs several automated actions to assist with technical analysis:

  • Trend Line Mapping: It automatically draws trend lines connecting consecutive highs and lows. This allows you to see the immediate trajectory of the market price.
  • Horizontal Support/Resistance: For specific levels, the tool can project horizontal lines. These act as "markers" for areas where price has historically interacted with significant structural points.
  • Take Profit Projections: One of the more advanced features is the automatic calculation of potential target zones. Based on the angle and distance between identified high/low points, the script calculates and draws three different possible levels (labeled as targets) where a trend might exhaust or reverse.
  • On-Screen Reporting: The script provides a text summary directly on your chart window. This summary lists the specific price coordinates of the current Highs and Lows and confirms whether the data currently being displayed is based on the standard TD logic or the Fractal method.

Key Customizations

The tool is designed to be highly adjustable to suit different trading styles:

  • Visibility: You can choose how many "steps" (consecutive points) of analysis you want to see at once.
  • Toggle Features: You have the ability to turn specific visual aids on or off, such as the trend lines, horizontal levels, or the take-profit projections.
  • Color Coordination: The script uses a variety of colors to differentiate between different trend steps, making it easier to distinguish between immediate and long-term price structures at a glance.
