GANN VooDoo Lines

Gann Square of 9 - TOS Scale Edition is a high-precision conversion of the classic ThinkOrSwim (TOS) Gann Square of 9 tool, specifically rebuilt for Pine Script v6. It is designed for traders who rely on mathematical price rotations to identify hidden support and resistance levels.

Unlike standard horizontal line tools, this version is specifically engineered to "handshake" with the TradingView price scale, ensuring that every mathematical rotation is clearly labeled on your Y-axis for instant reference.

How to Use This Script

1. 1. Define Your Anchor Point:
   2. Find a major swing high or swing low on your chart.
      
      
   3. Open the script Settings (gear icon) and enter this value into the Manual Anchor Price field.
      
      
      1. Select Market Direction:
      2. Down (Support): Use this if your anchor is a Swing High. The script will calculate support levels below that price.
         
         
      3. Up (Resistance): Use this if your anchor is a Swing Low. The script will calculate resistance levels above that price.
         
         
         1. Adjust the Visual Scope:
         2. Use the Extend Right and Extend Left toggles. If both are checked, the Gann levels will act as infinite "Voodoo Lines" across your entire chart history.
            
            
            1. The "TOS Scale" Final Step (Crucial):
            2. To see the colored price boxes on your vertical axis, Right-click the Price Scale (the numbers on the right of your chart).
               
               
            3. Hover over Labels and ensure Indicator Value Labels is Checked.
               
               *IMPORTANT: Uncheck the option "No Overlapping Labels." Since Gann levels are mathematically precise, they can sometimes be close together; unchecking this forces TradingView to show every single level simultaneously, just like ThinkOrSwim.
