Correlation
Rolling Pearson correlation (-1 to 1) of two indicators' period-over-period returns over N paired observations. Flat or degenerate windows read no-signal instead of a fabricated number.
Correlation
Definition
Rolling Pearson correlation (-1 to 1) of two indicators' period-over-period returns over N paired observations. Flat or degenerate windows read no-signal instead of a fabricated number.
Parameters
Two indicators, Lookback observations (60)
Example
`Correlation(Price(AAPL), Price(QQQ), 60) < 0.3` (AAPL decoupling from QQQ)
Usage notes
Correlates returns, not price levels — two co-trending assets do not read 1.0 just for both going up.
