JC - Line Break Alert_v1
Download script
The JC - Line Break Alert is a specialized monitoring tool designed to track specific price levels on a financial chart and notify the user immediately when those levels are breached. It functions as an automated watchdog, ensuring that you don't have to constantly watch the screen to know when a price hits your target.
Core Functionality
The script allows users to define specific price points and choose between two primary monitoring methods:
- Line Mode: This focuses on a single price level. The script monitors the market movement and triggers an alert the moment the price crosses that specific line, whether it is moving up or down.
- Channel Mode: This monitors two distinct price levels, effectively creating a "channel" or zone. It detects movements in both directions: it will alert you if the price breaks upward through the top level or downward through the bottom level.
Detection Logic
The tool evaluates market data in real-time based on your preference for "Tick Mode."
- In Tick Mode, the script analyzes the very latest price updates to provide high-sensitivity alerts.
- If disabled, it looks at the opening prices of historical candles to monitor movement on a slightly broader basis.
The logic is designed to identify the exact moment a price transition occurs (e.g., moving from below the target to above it). To prevent the system from sending repetitive notifications for the same event, it includes a "Deactivate" feature; once a breakout is detected and an alert is fired, the script can be set to ignore further crossings until the system is reset.
Notification System
When a price breach occurs, the script can communicate with you through several channels simultaneously:
- Audio Alerts: Plays a specific sound file a designated number of times.
- Visual Pop-ups: Displays a clear alert message on your trading platform screen, specifying the asset, timeframe, and the exact price reached.
- Email Notifications: Sends an automated email to your registered account providing a written record of the breakout.
Visual Representation
The script draws horizontal lines directly on your chart at your specified price points, providing a clear visual reference of your targets while it performs its background monitoring.
