What to Watch
Unusual right now
Recent correlation (+72%) is 2.2σ from the long-run average of -30% — pair is behaving differently than usual.
Tighter in drawdowns
Pair moves more tightly when both fall (+62%) than when both rise (-13%) — typical risk-off behaviour.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
Time Series
Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.

Stability
How the correlation evolves over time. A stable line means the relationship is reliable; large swings signal regime-dependent behavior.
