i-Sessions_v1
Download script
This script is designed as a visual navigation tool for traders to clearly identify and distinguish between different global trading sessions on their price charts. Instead of manually tracking time zones, the tool automatically maps out these key periods visually.
Core Functionality
Visual Session Mapping The primary purpose of this tool is to highlight three major global markets: Asia, Europe, and the United States. It creates distinct colored rectangular zones on your chart for each of these sessions. By looking at the chart, a trader can instantly see which global market is currently active or which period they are viewing in historical data.
Customizable Session Windows The tool allows you to define the exact start and end times for each session. For example, you can specify when the Asian markets open and close, as well as the corresponding windows for the European and American sessions. Additionally, you can choose specific colors for each region to make the chart easier to read at a glance.
Dynamic Historical Tracking The script doesn't just show the current time; it calculates and draws these session boxes over a significant historical period (determined by your settings). It automatically moves backward day-by-day to ensure that every trading day in the past is accurately labeled with its respective market hours.
Intelligent Price Scaling To ensure the visual blocks are useful for analysis, the script identifies the highest and lowest price points reached during each specific session. It then scales the height of the colored boxes to fit those extremes. This means that rather than being a static box of a fixed size, the rectangle expands to encompass the full range of price movement that occurred during that specific trading window.
Automated Maintenance The logic is built to be "clean." When you load the tool onto a chart, it generates the necessary objects; if you remove the tool, it automatically clears those boxes from your screen so it does not leave any leftover markings on your workspace.
