Is correlation between 2 time-series a useful indicator? In currency pairs for example, sometimes the correlation between 2 pairs (e.g. EUR/USD and GBP/USD) for the past x days is strong, but it can weaken very fast. Should I just take the average over time and go with it, or is there a better indicator to measure a relation between 2 time-series?(adsbygoogle = window.adsbygoogle || []).push({});
