I have stopped trading the USD/JPY. If you look at the chart you can see it’s flat lining with no price swings. Take a look at the ATR on different time frames, the intraday isn’t that great either.
The average weekly range was around 430 points just prior to 2009, and since then it has fallen lower and lower, and now stands at a 117 points PER WEEK. The average daily trading range has often been in the 50-60 points region, sometimes more, but it has dropped off sharply to what must be close to an all-time low of just 31 points.
It is probably best to concentrate on the other major currency pairs instead, such as the GBP/USD and EUR/USD pairs for example, but watch that EUR slide!!
