Sessions
Download script
This tool is designed for MetaTrader 4 to provide a clear visual breakdown of the global financial markets by highlighting specific trading sessions. It allows traders to see at a glance which geographic regions (Asia, Europe, and the USA) are currently active or were active in the past.
Core Functionality
Visual Session Mapping The script automatically draws colored rectangles on your chart to represent the trading windows for three major global markets:
- Asia: Typically highlights early morning activity.
- Europe: Highlights mid-day trading periods.
- USA: Highlights late-day American market movements.
Each session can be customized with its own specific start and end times, as well as unique colors to ensure the chart remains easy to read at a glance.
Automated Price Tracking Beyond simply marking the time, the logic calculates the high and low price points reached during each specific session.
- Dynamic Highs and Lows: The tool identifies the highest price reached within a session's window and draws a visual boundary for it.
- Real-time Price Labels: For the most recent trading day, the script provides specific text labels showing the exact prices at those boundaries. This helps traders identify "key levels"—the highs and lows that often act as support or resistance for future price action.
Key Features for Traders
- Historical Context: The tool doesn't just show today's session; it can project these colored blocks back over a significant number of previous days (user-adjustable). This allows you to analyze historical patterns and see how price behaves during specific times of the day across different weeks.
- Clean Chart Integration: The rectangles are designed to sit in the background of your chart, ensuring that they provide information without cluttering your view of the price candles.
- Customizable Aesthetics: You can personalize the font size, colors, and offsets of the labels to match your specific trading workspace layout.
- Smart Date Handling: The logic includes an internal calendar system that automatically accounts for different month lengths and leap years, ensuring that session blocks are placed accurately on the correct dates without manual adjustment.
