Price Alert: USD/JPY Testing Key Trend SupportU.S. Dollar / Japanese YenFOREXCOM:USDJPYFOREXcomUSD/JPY is testing critical support this week at 146.54/70- a region defined by the March low and the 38.2% retracement of the April advance. Note that basic trendline support extending off the yearly low converges on this threshold into the October open and the focus is on a possible inflection off this key zone. Initial resistance is eyed with the 200-day moving average (currently ~148.30) and is backed by the December low / May high / 61.8% retracement of the August decline at 148.65/84- a topside breach / close above this threshold would be needed to mark resumption of the broader uptrend. A break below this key threshold would threaten another bout of accelerated losses with subsequent support objectives seen at the May high-week close (HWC) at 145.63 and a key Fibonacci confluent at 144.10/52- look for a larger reaction there IF reached. Bottom Line: The October opening-range is taking shape just above multi-month uptrend support. A good zone to reduce short-exposure / lower protective stops- watch the weekly closes and look for a breakout monthly range in the days ahead of guidance here -MB
