USDJPY POTENTIAL BUY (FIB,S/R LINES)

USDJPY has been dropping for a while. I'm not completely sure but I marked up the chart, please feel free to comment/ask questions. I'm 18yrs old, so I'm doing my best. I didn't get any ideas from anyone else, I did it all on my own.

There's also No High Impact events for USD until Wednesday 22nd.
