This is not a perfect head and shoulders - and it is rather unusual to find a perfect pattern. I say what I see: 1. One big H&S on GBPJPY (1D). 2. Price had collapsed south from the base, almost the distance of the head. 3. Price is re-challenging the base at an important structure level.
There is an opportunity here for a controlled affordable loss (alias stop-loss). Did I say loss? Yes I did - so if you short this and lose your money kindly sue yourself.
