[c3s] CWS - M2 Global Liquidity Index & BTC Correlation

[c3s] CWS - M2 Global Liquidity Index with Offset BTC Correlation

This custom indicator visualizes and analyzes the relationship between the global M2 money supply and Bitcoin (BTC) price movements. It calculates the correlation between these two variables to provide insights into how changes in global liquidity may impact Bitcoin’s price over time.

Key Features:

1. Global M2 Liquidity Index Calculation:
   
   Fetches M2 money supply data from multiple economies (China, US, EU, Japan, UK) and normalizes using currency exchange rates (e.g., CNY/USD, EUR/USD).
   
   Combines all M2 data points and normalizes by dividing by 1 trillion (1e12) for easier visualization.
   
   
2. Offset for M2 Data:
   
   The offset parameter allows users to shift the M2 data by a specified number of days, helping track the influence of past global liquidity on Bitcoin.
   
   
3. BTC Price Correlation:
   
   Computes the correlation between shifted global M2 liquidity and Bitcoin (BTC) price, using a 52-day lookback period by default.
   
   
4. Correlation Quality Display:
   
   Categorizes correlation quality as:
   
   Excellent: Correlation >= 0.8
   
   Good: Correlation >= 0.6 and < 0.8
   
   Weak: Correlation >= 0.4 and < 0.6
   
   Very Weak: Correlation < 0.4
   
   Displays correlation quality as a label on the chart for easy assessment.
   
   
5. Visual Enhancements:Labels: Displays dynamic labels on the chart with metrics like M2 value and correlation.
   
   Plot Shapes: Uses shapes to indicate data availability for global M2 and correlation.
   
   Data Table: Optionally shows a data table in the top-right corner summarizing:
   
   Global M2 value (in trillions)
   
   The correlation between global M2 and BTC
   
   The correlation quality
   
   
6. Optional Debugging:Debug plots help identify when data is missing for M2 or correlation, ensuring transparency and accurate functionality.
