So if you only check on lower timeframe chart, you might be mislead by the fluctuations.
Lets go back to monthly chart. There is a long-term corrective triangle wave for USDJPY which seems about to end at the end of 5th wave. The warning signal in Jan is the signal.
USDJPY is very likely to break through the triange to 114 for the new impulse grand super ascending wave. 116 could be also the option for the end of this wave.
But that would take months to finsh.
So what you need is using the idea of this monthly chart to guide your trade in real trading world. Keeping finding bull signal or entry signal to open a long order to follow the main trend.
