GBP/JPY rose further to 148.09 last week but lost momentum ahead of 148.42 resistance. Considering bearish divergence condition in 4 hour MACD, a short term top is in place. Initial bias is neutral this week for more consolidation. Deeper pull back might be seen. But in that case, downside should be contained by 38.2% retracement of 135.58 to 148.09 at 143.31 and bring rise resumption. Break of 148.42 will target 150.42 long term fibonacci level first. Break there will pave the way to 100% projection of 122.36 to 148.42 from 135.58 at 161.64.
In the bigger picture, based on current momentum, rise from 122.36 bottom should be developing into a medium term move. Break of 38.2% retracement of 195.86 to 122.36 at 150.42 should pave the way to 61.8% retracement at 167.78. This will now be the favored case as long as 135.58 support holds.
In the longer term picture, based on the impulsive structure of the decline from 195.86 to 122.36, such fall should not be completed yet. But we will now pay close attention to the structure of the rise from 122.36 to determine whether it's a corrective move, or an impulsive move. That would decide whether a break of 116.83 low would be seen.
