The GBP/USD could be completing a wave B (green) if price manages to make a bullish bounce at the Fibonacci support levels. A break below the bottom and 100% Fib could, however, invalid the bullish ABC (green) wave pattern.
The GBP/USD is expected to make at least one more lower low which could be finishing a final wave 5 (brown) of wave C (orange). The Fibonacci retracement levels are key support zones.
