USD/JPY’s rise from 127.20 resumed last week by breaking through 137.90 resistance. But as a temporary top was formed at 138.73, initial bias is turned neutral this week first. Downside of retreat should be contained by 136.31 support to bring another rally. Break of 138.73 will turn bias back to the upside for 100% projection of 127.20 to 137.90 from 129.62 at 140.32. Break there will target 142.48 fibonacci level.
In the bigger picture, rise from 127.20 is seen as the second leg of the corrective pattern from 151.93 high. Stronger rally would be seen to 61.8% retracement of 151.93 to 127.20 at 136.34. Sustained break there will pave the way back to retest 151.93. On the downside, however, break of 133.73 support will argue that the pattern could have started the third leg through 127.20 low.
In the long term picture, price action from 151.93 is seen as developing into a corrective pattern to up trend from 75.56 (2011 low). While deeper decline cannot be ruled out, downside should be contained by 38.2% retracement of 75.56 to 151.93 at 122.75.
