The USD/JPY broke below the support trend line (dotted green) but both a bullish bounce or bearish break remains valid options. The direction will depend on the next breakout.
The USD/JPY could be building a bearish ABC (purple) within wave Y (pink) as indicated in the image. A break below the support trend line (green) would confirm the bearish breakout. A break above the resistance trend line (red) makes it likely that the wave X (pink) is still ongoing.
