Download script
This tool is designed to identify and visually map specific price "zones" on a trading chart based on defined time windows during the trading day. Instead of looking at the entire day's price action, it isolates specific hours to determine key historical highs and lows that may act as significant levels for future price movement.
Core Logic Overview
The script operates by scanning the market history and categorizing price data into two distinct chronological blocks. It identifies the highest and lowest prices reached during these periods and projects them across the chart.
1. Time Window Definition
The tool is configured to monitor two specific sessions:
- Session 1: A morning period (e.g., 05:00 to 09:00).
- Session 2: An afternoon period (e.g., 12:00 to 15:00).
2. Dynamic Range Identification
As the script moves through the historical data, it "listens" for the start and end of these specific time windows. During these periods, it continuously tracks:
- The Highest Price reached.
- The Lowest Price reached.
Once a session ends, the highest and lowest points captured during that timeframe are locked in as the boundaries for that specific zone.
3. Visual Mapping
The script then paints these boundaries onto your chart as horizontal lines (Zones).
- Zone 1: Represents the price range established during the first morning session.
- Zone 2: Represents the price range established during the second afternoon session.
4. Daily Reset Mechanism
The logic is designed to be "day-aware." It automatically detects when a new day begins on the calendar. When the script moves into a new trading day, it clears all previous calculations and resets the trackers. This ensures that the zones shown on your screen are always relevant to the current day's price action rather than carry over old data from previous days.
Summary for the User
Essentially, this tool helps you see the "high-water marks" and "low-water marks" of the morning and afternoon sessions. By identifying these boundaries, it allows you to visualize where the market spent its most significant time during peak hours, helping you identify potential areas of interest for your own trading analysis.
