Download script
This script is a visual information dashboard designed for the MetaTrader 4 trading platform. Its primary purpose is to display real-time market data in a clean, organized graphical box on your trading chart, allowing you to monitor key statistics at a glance without cluttering your workspace.
Core Functionality
The script creates an interactive "Information Rectangle" on your screen. Instead of just showing raw numbers in a list, it houses the data inside a customizable background box with specific colors, borders, and fonts. It automatically handles the placement of text so that all information is neatly stacked and aligned.
Key Features & Data Displayed
The dashboard is designed to be modular, meaning you can choose which pieces of information to display via the settings:
- Symbol Information: Displays the current trading pair and its timeframe.
- Spread Tracking: Shows the current market spread (the difference between the buy and sell price), which is vital for understanding transaction costs in real-time.
- High/Low Range: Calculates and displays the price range (High to Low) of the current daily candle, giving you a quick sense of today's volatility.
Intelligent Logic & Design
To ensure a smooth user experience, the script employs several "smart" behaviors:
- Dynamic Positioning: You can choose which corner of the chart the dashboard appears in (e.g., bottom-right, top-left, etc.). The script automatically calculates the correct coordinate directions to ensure the text stays perfectly aligned with the chosen corner.
- Auto-Scaling Geometry: One of the more advanced features is how the rectangle handles text size. The script calculates the width of the text being displayed and automatically adjusts the size of the background rectangle to fit that text perfectly. This prevents the box from being too small for long words or unnecessarily large for short ones.
- Real-Time Updates: The script continuously refreshes the data. It uses a timer system to ensure that as market prices change, the Spread and High/Low values update instantly on your screen.
- Clean Workspace Management: When you load the script, it automatically clears any old versions of itself from the chart to prevent "ghost" images. When you remove the script, it cleans up after itself by deleting the dashboard objects, leaving your chart exactly as it was before.
Summary for the User
Think of this as a customizable heads-up display (HUD). It takes raw market data that is usually hidden in menus and pulls it onto your main screen into a stylized, professional box. You can customize colors, fonts, and positions to match your trading style, while the script handles all the math required to keep the layout organized and accurate.
