Tristan's W%R Strategy

Overview:
This strategy uses the raw Williams %R oscillator to automatically generate buy and sell signals based on overbought and oversold levels. It is session-aware, allowing you to restrict trades to specific market hours (New York, London, or Asia).

Key Features:

• Buy Signal: Fires whenever the raw Williams %R is at or below the oversold level (default −100).
  
• Sell Signal: Fires whenever the raw Williams %R is at or above the overbought level (default 0).
  
• Session Filtering: Only triggers trades during the selected session (All, New York, London, or Asia).
  
• Pyramiding: Allows multiple trades to stack, so every qualifying signal results in a new trade.
  
• Alerts: Optional alerts for automation via webhook or broker integration.
  
• Session Highlight: Background shading indicates when the selected session is active.
  

How to Use:

• Set the Williams %R length, overbought, and oversold levels to match your trading style.
  
• Select the session you want the strategy to be active in (New York, London, or Asia).
  
• Enable alerts if you plan to automate trades with an API.
  
• Add the strategy to your chart. It will execute trades automatically whenever the raw %R meets the configured thresholds during the selected session.
  
• Adjust pyramiding if you want to limit the number of stacked trades per session.
  

Note:
This script uses the raw W%R signal vs the smoothed one because I found it to be more accurate for automated trading.

Every qualifying signal results in a trade, even if positions are already open.
