Is GBP in overbought territory?

GBPUSD behaves like EURUSD, but unlike EURUSD, GBP was not in a downtrend before it went up and traded range-bound at1.57-1.56300. Now the correlation with EURUSD is reaching absolute values, which means that the currency is also in overbought territory and I think that it’s dangerous to keep buying. I would recommend refraining from launching positions until next week.
