GBPUSD had a very volatile week with the interest rate hike and the non-farm payroll. It's too early to be optimistic on sterling in regards of how the price reacted to those events. My game plan is to wait for reversal sign @ 1.2960-1.2990, to see if it can get support there. If so , it could be a good opportunity to long GBPUSD in my perspective.
In terms of reversal sign for daily chart analysis, at least on hourly chart is necessary, and it's better to wait for a 4hr chart one.
