IBD Style RS Rating Line Indicator

Purpose

• Measures relative performance, not just price action.
  
• Recreates the IBD-style 1–99 RS Rating inside TradingView.
  

RS Line

• Plots stock price relative to a benchmark (default: SPX).
  
• Scaled for readability; supports indices and sectors.
  
• Optional MA overlays and positive/negative fill zones.
  

RS New Highs / New Lows

• Scans a user-defined lookback.
  
• Marks RS new highs (blue) and new lows (red).
  
• Modes for historical, last-bar-only, or “RS leads price.”
  

RS Rating (1–99)

• Calculates a weighted performance score over 1–12 months.
  
• Compares this score to market-wide thresholds pulled via request.seed().
  
• Converts score into percentile bands (e.g., 70–89, 90–98).
  
• Assigns 99 to top leaders and 1 to laggards.
  

Fallback Logic

• Missing environment data = shows “RS” without a number.
  
• Replay mode uses fixed thresholds to approximate ratings.
  

Output

• Clean label showing RS Rating near the RS line.
  
• Helps traders instantly judge whether a stock is a true leader.
