Much volatility was seen in USD/JPY last week but the pair's rally attempt was limited at 77.48. Also, there is no follow through buying to help USD/JPY sustain above near term falling trend line yet. More choppy sideway trading could be seen between 76.11 and 77.48 initially this week. But we'll remain slightly bearish in USD/JPY as long as 77.48 resistance holds and favor an eventual downside break out through 75.94 support. Nevertheless, sustained break of 77.48 will argue that whole decline from 85.51 is possibly over and further rise would be seen back towards 80.23 resistance.
In the bigger picture, USD/JPY is still staying well inside the falling channel that started back in 2007 at 124.13. There is no indication of trend reversal yet even though medium term downside momentum is diminishing with bullish convergence condition in weekly MACD. Such down trend is still in favor to continue to 70 psychological level. In any case, break of 80.23 resistance is first needed to indicate completion of fall from 85.51. Secondly, break of 85.51 is needed to be the first signal of medium term reversal. Otherwise, we'll stay cautiously bearish in the pair.
In the long term picture, current decline suggests that the long term down trend in USD/JPY is still in progress. Such down trend is expected to extend further into uncharted territory with 70 psychological level as next target. In any case, we'd at least need to see sustained break of 85.51 before considering trend reversal.
