The GBP/USD made a strong bullish bounce at the 78.6% Fibonacci level of wave X vs W, which was also an inverted head and shoulders reversal pattern (purple boxes). The bullish momentum seems to be confirming a larger bullish correction within wave 2 (pink) via a WXY (purple) pattern. The break of the downtrend channel could confirm this wave pattern whereas a break below the Fib level could indicate a continuation of the downtrend.
The GBP/USD seems to have completed 5 bearish waves (green) within a wave C (blue) at the 78.6% Fib. The bullish bounce is showing strong bullish momentum and is most likely a bullish wave A (blue) of a larger ABC pattern.
