The USD/JPY seems like forming a Head and Shoulder pattern on a 30 minute time frame. If the price does break the neck line of this H&S should pattern, then we could see the price near its minor support zone (110.65-100.46). Moreover, the price action has also broken its upward rising channel which suggests that the price is weakening. Finally, the RSI is showing a very clear sign of deflection between the price action and the RSI, which suggests that the strong bias could be towards the downside.
The USDJPY pair is trading below its 50 day (shown in green) moving average but still well above its 100 day (shown in yellow) moving average.
