The U.S. dollar made its recent break to the upside against the Yen around 108.830, and reached highs of 109.985 a couple of times in last week's session but failed to progress further. It has fallen below a critical support price level at 109.850 which has activated a short sell signal. A break below 109.590 would confirm the change of direction to the downside with a price target at 109.340, 109.950, and 108.950.
