On the short term, GBPJPY pair is trying to retest the breakout level from the upward price channel along with the support level broken at 152.50 which should now act as a resistance
My technical bias will be bearish on the pair from the levels of resistance 152.50 along with the broken trendline and levels of 38.20% fibo retracement to resume the downtrend and target the last low again at 150.65
