The GBP/USD is building a bearish correction which is probably part of a larger a wave 4 (brown). The 38.2% and 50% Fib levels are expected to act as support, but this wave pattern is invalidated if price breaks below the 61.8% Fibonacci level of wave 4 vs 3.
The GBP/USD is having troubles breaking below the support with the downtrend channel. A break above the resistance (orange) could indicate a potential bullish bounce and breakout.
The EUR/USD is building a bearish trend channel but price action remains choppy and corrective. This is making a wave 1-2 (pink) pattern more likely and the next potential support zone could be at the 50% Fibonacci level. A break below the bottom (purple box) invalidates this wave pattern.
The EUR/USD again broke below the support trend line (dotted green) and fell below 1.18. Price seems to be slowly moving towards the Fibonacci levels of wave 2.
The USD/JPY has bounced at the bottom / support (green) of the uptrend channel and is showing a break above the resistance trend line (dotted orange). This could be ware of a wave 3 (blue).
The USD/JPY bullish breakout could still face some resistance from the previous highs.
