The Yen price dropped like a stone in the past few weeks. Due to factors as dollar strength, Russian tzar wars in Ukraine, inflation. Whatever reason you may find - find it! Technically speaking, the pair is extremely overbought, it demands correction from the bottom to top of 2/3 healthy way down before it can rise again. Many scholars here, are building lots of short term shorts to catch that correction wave. And it’s good, as it adds to volatility and unstable pair condition. My recommendation is watching closely the important levels of support and resistance, looking down and short peaks with correctional waves sell. Good luck!
