Opal
Title: Opal Lines
Short Title: Opal Lines
Description:
Opal Lines is a dynamic overlay indicator that plots horizontal price levels at the open of key market sessions throughout the trading day, based on Eastern Time (ET). Designed for traders who rely on session-based price action, it marks significant intraday events such as the European Open (3:00 AM ET), Gold Open (8:20 AM ET), Regular Market Open (9:30 AM ET), and Globex Open (6:00 PM ET), among others. Each line is color-coded and toggleable via inputs, allowing users to customize which sessions they want to track.
Unlike generic time-based tools, Opal Lines captures the opening price at precise minute intervals and extends these levels across the chart until the daily reset at 5:00 PM ET (except for the Globex line, which persists into the next day). This makes it ideal for identifying support/resistance zones, breakout levels, or reference points tied to major market openings. Traders can use it across forex, futures, equities, or commodities to align their strategies with global session dynamics.
Key Features:
Seven toggleable session lines with distinct colors for easy identification.
Time-specific logic using ET, adaptable to any chart timeframe.
Persistent lines that reset daily, with Globex extending overnight.
Lightweight and overlay-friendly, preserving chart clarity.
How to Use:
Add the indicator to your chart and enable the sessions relevant to your trading style. Watch for price interactions with these levels—e.g., bounces, breaks, or retests—especially during high-volume periods. Combine with other tools like volume or oscillators for confirmation.
Note: Ensure your chart’s timezone is set to “America/New_York” (ET) for accurate alignment.
