Hoggy, I cannot really help you with GBP currently as I do not have any triggers in lay on it.
I became bullish on cable when it broke 1.5730 up.
To me it is bullish until it becomes bearish again.
The reason for this may simply be that Yellen is not going to taper soon and that itself continues to hurt the USD. This in effect means all other currencies strengthen.
Also there is talk of rising interest rates sooner rather than later in the UK and that keeps the POUND underpinned.
I may be well of the mark as currencies are no longer my domain.
Plan your trade, trade your plan!
