If we look at 2016 there was huge gain on yen and prices droppet below 100 yen per dollar , most of that drop was recovered up too 118 per dollar before a dovish and directionaless 2017. I'm wieving 2017 as an inside bar and break below 108 will cause a massive move further down. But if it holds I expect a much weaker yen and go long. Please also see my us dollar chart
