StrikeZone Pro is a trading indicator designed to identify and mark price zones based on the opening minutes of the London (08:00) and New York (14:30) trading sessions. It records price action during a configurable opening range period (default 15 minutes) to establish a zone defined by the highest high and lowest low within that timeframe. This zone is visually represented on the chart as a filled rectangle with labels indicating the exact high, low, and pip width.

The indicator offers two signal modes:
1. Breakout mode triggers a single alert per session when price closes above or below the zone boundaries.
2. Retest mode waits for a breakout and then signals when price returns to retest the zone boundary, allowing multiple alerts per day.

Alerts are generated only on closed bars to reduce false signals and can be configured to display popups, play sounds, or send email notifications. Each alert includes details such as symbol, time, session, and signal type.

StrikeZone Pro supports independent tracking of London and New York sessions with distinct colors and is optimized for use on 1-minute or 5-minute charts. Users should ensure their broker's server time aligns with session start times for accurate zone detection.
