1-Month RS histogram

Original idea: x.com/jfsrev/status/1806709652975141131

I would recommend to pair it with 3-Month Weighted RS to visualize both short-term and medium-term RS for the ticker.

• Definition: Takes the direct price ratio = close / SPY close.
  
  Tracks that ratio over a rolling lookback (default = 26 trading days ≈ 1 month).
  
  Computes the percentile rank of today’s RS relative to the last N bars.
  
  Shows it as a blue-colored histogram.
  
  
• Interpretation: If percentile is high, the stock has been stronger than SPY over that lookback window; if low, weaker.
  
  
• Assumption: All days in the lookback have equal weight → recent vs older returns treated the same.
  
  

Majority of code and indicator idea is taken from an old post likely by @ChartsLector. I couldn't find the actual post.
