On the 1D time frame, a strong positive correlation relationship emerges - where previously on the 4h time-frame the correlation looked relationship-less and "noisy".
However, looking back at the Daily correlation over the last 2-3 years for GU and EU one noticeable and significant trend emerges -
A steep fall in correlation, either from positive-lower positive, or positive to negative, is historically ALWAYS followed shortly by a plummet/ Sell-off in GBP$.
Thus as we see below GU v EU correlation has been descending and has just turned negative - so in my opinion we should consider selling GU as if history holds true an aggressive sell off on the daily is close by.
