0.86

BTC vs Gold ยท very high

Recommended next actions

  • Plot both series after z-score normalization to show the shared shape without scale differences.
  • Run rolling or windowed similarity if you expect the relationship to change over time.
  • Use structural-profile similarity when scales, frequencies, or observation modes differ too much for raw-shape comparison.
  • Inspect spectral or seasonality-aware models because the two series share rhythm strongly.
Use this as an interpretable comparison summary. If you need alignment paths or distance matrices, pair the result with a lower-level similarity library.
