GbpJpy- Where to sell?

Since the 168.50 top reached in April, GbpJpy has started to trade in a range with a bottom around 160 zone.
Now the pair is approaching the higher boundary of the range and this can offer a good opportunity for bears.
Also, the rise from 162 is a rising wedge that can be a signal that bulls are getting tired.
Selling around 168 can have a good 1:3 R: R and a new high would negate this scenario
