From the technical perspective, clearly GJ already made a swing low right now which indicates a higher low. supported by rejection from fibonacci 61.8% a.k.a the Golden Ratio, make it clear for me where this currency pair will go. In the other hands, using stochastic oscillator as an indicators which i mostly used to see where the divergence areas are, we could see a bullish divergence also in this matter. long story short, all the technical perspective shown from GBPJPY is going Long.
this trade will fail if the stop loss is hit, so risk management is also a key point to do here. never forget to use risk management everytime you trade in any financial instruments. Good Luck!
