GM board...pennies the relationship between EUR/GBP and the beast is a complex issue but I use EUR/GBP to determine movements of the beast and GBP/USD. The complexity stems from the fact that the Yen is in the equation.BGP/JPY is basically a synthetic pair...IOW if you have a US dollars account and go long on the beast then your transaction is to buy GBP/USD and sell USD/JPY..this cancels USD and leaves a net long on GBP/JPY.EUR/GBP helps me measure the strength of the Euro and the pound at any given time as well as a glimpse of EUR/USD.The beast does not correlate perfectly with GBP/USD but usually correlates with trend direction so EUR/GBP is what I keep my eye on. As I said...its a complex issue but it works well for me
