Duration of Correlations

Hi, I’m starting testing some approaches on forex that have to do with pairs being correlated (either positive or negative correlations will do)

What I want to ask is, what do you believe? Are strong positive correlations (like 90 and above) or strong negative correlations (like -90 and below) lasting longer in currency pairs? I mean if a set of currency pairs gets into correlation (no matter the Timeframe) is it more possible to stay longer this way (more candles of that Timeframe period) if it is a positive or negative correlation based on your experience?

Or is there no difference and no pattern and both can keep being correlated as long or as short as they want?

Thanks for any replies!
Have a nice day and stay safe :slight_smile:
