The pair has been limited below 1.5165 during the Asian session after failing to stabilize above 1.5220 with a four-hour closing and now, GBPUSD trades below moving averages.
In the interim, GBPUSD started to move below the previous low, while RSI stabilizes below 50.00 levels and that reflects weakness in the trend.
As far as 1.5220 holds, we will be bearish and a break below 1.5100 will affirm and accelerate, targeting 1.5230 where 127.2% Fibonacci exists.
