Looking to short GBP/JPY around 142.55:
Retest area of H&S neckline
38.2 FIB area
Price now trading against moving averages
Recent rejecting of 1D trend line
A slight pull back to 108.6 area will give a potential:
38.2 retracement
rejection of previous lower time frame descending trend
rejection of higher timeframe support/resistance.
Good R/R comes from targeting previous strong higher timeframe support/resistance
