Patterns are always repeat on its own way. Check this daily chart of USDJPY, you will find out the answer.
To begining a new swing or new trend, USDJPY needs to prepare itself for a while. Every time it want to drop, it moves with four wave sideways and drop down on its fifth way WITH RSI DIV CLEARLY. Similar things happen when it want to rise.
On the blue channel, we believe that USDJPY want to repeat the similar patter now. And it will rise up back to the red resistance zone which we assumed as valid now. It will drop after breaking down the channel FOR A NEW TREND. So we drop our short trade signal on UJ now manually with 30 pips profit.
