GBP is trading higher on account of policy divergence of major central banks. BoE governor Mark Carney also said earlier this week that rate hike might happen earlier given the performance of the UK economy.
Technically Cable is facing strong resistance around 1.5650 and break above will extend gains till 1.5680/1.5750/1.5800.
On the downside it is weak below 1.5600. Short term invalidation only below 1.5550.
It is good to buy at dips around 1.5650-55 with SL around 1.5595 for TP of 1.5750.
