SD Median NUPL-Z

🧠 Overview
SD Median NUPL-Z is a trend-following indicator that leverages a normalized version of Bitcoin’s Net Unrealized Profit/Loss (NUPL) metric, filtered through a median-based volatility band. Unlike traditional NUPL which is often used to spot extremes, this indicator is designed to identify sustained directional trends — entering only when both on-chain momentum and price structure align.

🧩 Key Features

• Z-Scored NUPL Trend Engine: Normalizes NUPL using rolling mean and standard deviation to create a smoothed trend signal.
  
  
• Price Structure Filter: Implements a median-based price band to avoid false entries during short-term volatility.
  
  
• Custom Thresholds: User-defined thresholds determine when the trend signal is strong enough to justify a long or short directional bias.
  
  
• Directional Candle Coloring: Reinforces current trend regime visually with aqua (bullish) and red (bearish) plots and candles.
  
  
• Optimized for BTC: Uses Bitcoin’s Market Cap and Realized Cap to construct the NUPL input.
  

🔍 How It Works

• On-Chain Core: NUPL is calculated as the percentage of unrealized profit in the market: (Market Cap - Realized Cap) / Market Cap * 100.
  
  
• Z-Score Transformation: The raw NUPL value is normalized using a rolling average and standard deviation over a set window (default 134 days), producing the NUPL-Z series.
  
  
• Median-Based Price Filter: A rolling 50th percentile (median) of price is used alongside its own standard deviation to create upper and lower bounds.
  These bounds define a "volatility corridor" around price; the trend signal is only acted upon if price confirms by staying outside these bands.
  

Signal Logic:

• A Long signal is triggered when NUPL-Z rises above the long threshold and price is not below the lower band.
  
  
• A Short signal is triggered when NUPL-Z falls below the short threshold.
  
  
• State Variable (CD): Tracks the current market regime, used to control plotting and color changes.
  

🔁 Use Cases & Applications

• Momentum-Based Trend Following: Helps traders align with directional moves backed by both on-chain sentiment and supportive price structure.
  
  
• Filtered Entry Timing: Reduces premature or noise-based entries by requiring price confirmation before committing to NUPL-based signals.
  
  
• Best Suited for BTC: This tool is designed specifically around Bitcoin’s on-chain metrics and is not intended for altcoins or low-volume assets.
  

✅ Conclusion
SD Median NUPL-Z repurposes a traditionally cyclical valuation tool into a modern trend-following signal by combining statistical normalization with dynamic price structure filtering. It offers a more robust way to participate in high-conviction directional trends, reducing the likelihood of entering during short-lived counter moves.
