Download script
This script is designed to enhance your trading chart by automatically calculating and displaying the price distance of any trend lines you draw. Instead of having to manually calculate the difference between two points on a trend line, this tool does the math for you in real-time.
How it Works
The logic follows a simple three-step process every time the market updates or the chart refreshes:
- Detection: The script constantly scans your active trading chart to identify any "Trend" objects (trend lines) that you have placed manually.
- Calculation: Once it finds a trend line, it looks at the starting price and the ending price of that specific line. It calculates the vertical difference between these two points to determine exactly how many price pips or points the trend covers.
- Labeling: The script then automatically generates a text label on your chart. This label is placed right at the starting point of the trend line and displays the calculated distance (e.g., "Trend 50p.").
Key Features for the User
- Automatic Updates: You do not need to trigger the script manually; it monitors the objects on your screen dynamically.
- Visual Consistency: The generated text automatically matches the color of the trend line you drew, ensuring the chart remains clean and easy to read.
- Hidden Organization: To keep your workspace uncluttered, the labels are set to be "hidden" from the main object list, so they won't interfere with your ability to click on and move your primary trend lines.
In short, this tool acts as a personal assistant that automatically measures the "reach" of your trend lines, providing you with instant data on price movement without requiring manual calculations.
