The GBP/USD remains in an indecisive spot from a wave perspective. The main aspect to keep an eye on is whether price bounces or breaks at the top (red) resistance line of the downtrend channel. A bearish continuation, especially below the 100% Fibonacci level, could indicate an impulsive wave 3 pattern whereas a reversal could indicate a bullish wave count instead.
The GBP/USD has made a bullish retracement back to the top of the downtrend channel and the 144 ema, which is a key decision for a bearish bounce or bullish breakout. A bearish reaction could indicate a continuation of the wave 3 (green) whereas a breakout could either be part of a larger 4 (green) correction or the start of a new uptrend (green arrow), which will depend whether price can break above the 50-61.8% Fibonacci levels or not. Fro the moment, a bearish breakout seems the most likely scenario.
