USD/JPY opened higher than the Friday close to a small retracement in it's initial hour and price is now trying to push high (hourly view) with a wick formed above today's open on the next candle.
Markets could be primed for the Bank of Japan Chief Kuroda who is due to speak in the early hours of Monday and as per recent speeches he will likely be seeking to manipulate Yen strength to support Japanese exporters.
Let's wait and see what happens, the position here is long USD/JPY.
