I found this setup so convincing that might could give a short position.
Since the price bound multiple time along the acceding uptrend channel. it could might bound back down again.
+ the last Friday the "Pin Bar" was form on the gbpjpy daily chart. + which it was retraced back below 173.75, where it was hold at that level for sometime in 4H chart. where there is an evident from previous day indicate that some seller do make price to move down a bit around at 173.75.
I believe 173.75 - 173.70 could be use as entry point for short position, and 174.2 should be a good place for stop lost where is just slight above the pin-bar.
