What to Watch
Mostly stable
Correlation drifts a little but stays in the same neighbourhood.
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.
