Bitcoin Power Law Corridor + Z-score

This script visualizes the long-term Bitcoin Power Law Corridor, a conceptual model originally discussed by Harold Christopher Burger, and enhances it with a logarithmic Z-Score framework.
The indicator plots Bitcoin’s long-term regression curve together with estimated resistance and support bands based on power-law relationships between price and time since inception.

The added Z-Score expresses the statistical distance between price and the central regression line, using logarithmic scaling:

Z ≈ 0 → price near its long-term fair-value trajectory.

Z ≈ +2 → price near the lower corridor boundary (historically undervalued region).

Z ≈ −2 → price near the upper corridor boundary (historically overheated region).

This indicator is designed for visual and educational purposes only.
It should not be considered financial advice, a predictive model, or a signal provider.
Users should always combine this tool with other forms of technical, fundamental, and sentiment analysis to confirm confluence before making any decision.
