The 45 minutes chart shows that the currency pair is losing its upward momentum after touching its resistance level at 1,21954 (Fib 61.8%). Aroon p is at 85.71% and showing the possibility of further weakening of the pound against the dollar. Next price point of interest is at 1.21804 (Fib 78.%) if the currency pair sticks to its course. At this point I will take my profits and wait for another signal.
