GBP/USD and USD/JPY Correlation

Hi,

All along Ive heard people say that those two pairs have a strong reverse correlation, but when I look at Correlation Charts or online Correlation tools that I find the results usually suggest that there is little correlation between the two. Whats the case with these two pairs guys? Thanks!

The correlation is largely due to the Carry Trade. Carry traders like the GBP/JPY. When they sell (or buy) Yen and buy (or sell) Pound this influences the G/U and the U/J.

GU up and UJ up or GU up and UJ down?...both are correct and wrong..
if the correlation between pairs exist there should be some formulae
to calculate them...as far as i know there are no such things which mean what happen is "maybe" a coincidence...so corelation isnt a factor in trading judgement...news ,rumors,corelation,indecision
all can be found in your technical analisys and indicator...
so why spent more time talk about correlation than study ur technical...
just my opinion...

because it has same USD currency (can't be more silly than this i guess)

nippon export many goods to US so their currency tend to be goes with the same wind as US, till lately the Europe take more yen, and since the yen are mostly depend on how good is the export, while the buying power are better when the currency is up, then yen will be likely floating between this two great nation , no?
