JC - trial Line Break Alert
Download script
The JC - Line Break Alert is a specialized monitoring tool designed for traders who need real-time notifications when market prices reach specific, predefined levels. Instead of requiring you to watch the charts constantly, this script acts as an automated "watchdog" that triggers alerts based on your customized price targets.
Core Functionality
The logic operates in two distinct modes depending on your trading strategy:
1. Single Line Crossing (Line Mode) In this mode, you define one specific price point. The script monitors the market to see if the price moves from above that line to below it, or vice versa. The moment a "cross" occurs, the system registers the event and notifies you.
2. Channel Breakout (Channel Mode) This mode is designed for identifying "breakouts." You set two distinct price levels, effectively creating a corridor or channel. The script monitors for instances where the price moves outside of this boundaries:
- Breakout Up: Triggered when the price crosses above your upper boundary.
- Breakdown Down: Triggered when the price drops below your lower boundary.
How the Logic Works
To ensure accuracy, the script evaluates the market in the following ways:
- Price Tracking: You can choose whether the script monitors "Ticks" (the absolute live movement of price) or "Bar Data" (the prices at the open and close of a candle). This allows you to decide if you want instant reactions or confirmation based on completed candles.
- Notification System: When a breakout or crossing is detected, the script can perform several actions simultaneously:
- Audio Alerts: Plays specific sound files to grab your attention immediately.
- Pop-up Alerts: Displays a visual notification box on your trading platform containing the symbol name, timeframe, and the exact price reached.
- Email Notifications: Optionally sends an email summary directly to your inbox (if configured).
- Alert Management: The logic includes a "Deactivate" feature. If enabled, the script will alert you only once per breakout, preventing repeated notifications for the same movement. There is also a "Sleep" function in the channel mode to space out audio alerts, ensuring they remain clear and audible.
User Benefits
By using this script, traders can set their "danger zones" or "take-profit targets" ahead of time. The logic handles the heavy lifting of constant price surveillance, ensuring that you are notified the very second a significant market move occurs, regardless of whether you are currently looking at your screen.
