4. Price Validation: Confirms moves exceed ATR threshold

Trend Line Creation

1. Automatic Detection: Connects consecutive swing points
2. Forward Projection: Extends trend lines into the future
3. Channel Creation: Draws parallel lines above and below main trend
4. Real-time Updates: Adjusts as new swing points develop
