Auto Trend Channel + Buy/Sell Alerts

This indicator automatically detects trend channels using a linear regression line, and dynamically plots upper and lower channel boundaries based on standard deviation. It helps traders identify potential Buy and Sell zones with clear visual signals and customizable alerts.

💡 How It Works:
🧠 Regression-Based Channel: Calculates the central trend line using ta.linreg() over a user-defined length.

📏 Dynamic Boundaries: Upper and lower channel lines are offset by a multiplier of the standard deviation for precision volatility tracking.

✅ Buy Signals: Triggered when price crosses above the lower boundary — potential bounce entry.

❌ Sell Signals: Triggered when price crosses below the upper boundary — potential reversal exit.

🔔 Alerts Enabled: Get real-time alerts when price touches the channel lines.
