Definition. Correlation to BTC (7D) is the 7-day rolling correlation coefficient between BTC's returns and Bitcoin's returns, measuring how closely the asset's price movements track Bitcoin over a weekly period.

Interpretation. Values range from -1 to 1: 1 indicates perfect positive correlation (the asset moves in the same direction as BTC), -1 indicates perfect negative correlation (opposite direction), and 0 indicates no correlation.

This is the Point-in-Time (PiT) variant of Correlation to BTC (7D). PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
