GBP/JPY stayed in range of 142.58/145.67 last week and outlook is unchanged. Initial bias remains neutral this week first. On the upside, break of 145.67 will target 38.2% retracement of 156.59 to 139.88 at 146.26. Decisive break there will be a strong signal that fall from 156.59 has completed at 139.88, ahead of 139.29/47 key support zone. Further rally should then be seen to 149.30 resistance for confirmation. On the downside, though, break of 142.58 will turn bias back to the downside for retesting 139.88 low instead.
In the bigger picture, at this point decline from 156.59 is still seen as a corrective move. Focus remains on 139.29 cluster support (50% retracement of 122.36 to 156.59 at 139.47). Strong rebound from there will re-affirm the bullish case that rise from 122.36 is still to extend through 156.59 high. However, sustained break of 139.29/47 should confirm medium term reversal. GBP/JPY would then target a retest on 122.26 (2016 low).
In the longer term picture, the failure to sustain above 55 month EMA (now at 152.97) is mixing up the outlook. Nonetheless, as long as 139.29 holds, rise from 122.36 is in favor to extend to 50% retracement of 195.86 (2015high) 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.
