From my observation on the USD/JPY chart, there are signs that the pair may be forming a double top pattern. The current key top is around 156.0 – this is a strong resistance level that the price has reached twice without being able to break out. This is a warning sign for a possible reversal, especially when buying pressure starts to wane.
With the double top pattern, if the price drops and breaks through the support area near 152.0, I think there is a high chance that the pattern will be confirmed. In this scenario, the downtrend could continue, and the price could head towards the lower support area around 151.0. That would be a point where I would consider entering a short position if the downtrend is confirmed.
