Overall I believe we should see 0.8530 again as the rise has been like three climbing mountain tops, and it created a kind of strong rising wedge so the speak.
This will not bode well short-term and perhaps GBPUSD will move upwards sharply due to the larger fall of USDJPY affecting GBPJPY as a thought.
Strategy is SELL 0.8730-0.8780 and take profit 0.8578 for now.
