GBP/JPY rose to as high as 149.48 last week but failed to take out 149.70 resistance and retreated sharply. As it stays above 146.28 minor support, initial bias is neutral this week and another rise is mildly in favor. On the upside, decisive break of 149.70 will resume whole rise from 139.88 and target 153.84/156.59 resistance zone. On the downside, below 146.28 minor support will turn bias back to the downside for 142.76 instead.
In the bigger picture, as long as 139.29 cluster support (50% retracement of 122.36 to 156.59 at 139.47) holds, up trend from 122.36 (2016 low) would still extend beyond 156.69 high. However, decisive break of 139.29/47 will suggest that such up trend is completed and turn outlook bearish. In that case, next target is 61.8% retracement at 135.43.
In the longer term picture, as long as 139.29 holds, rise from 122.36 is in favor to extend to 50% retracement of 195.86 (2015 high) to 122.36 (2016 low) at 159.11, and possibly further to 61.8% retracement at 167.78 before completion. However, firm break of 139.29 will turn focus back to 116.83/122.36 support zone instead (116.83 as 2011 low).
