On daily and hourly Charts, GBPJPY has been testing a strong support for few days already.
RSI and MACD shows oversold conditions, inducing probable bullish behavior.
My advice will then be to wait for the upward crossing of the MACD, an a value of RSI closer than 50 to go long (Safe approach) or after the upper pattern starts, to go long (more risky)
You can then adapt your TP and SL according to risk management techniques.
PS: this is valid only if GBPJPY doesnt break the strong support.
Good luck
