GBP/JPY short opportunity

Looking into this trade for early next week or end of next week using ichimoku waves , time theory and %R .

The waves are forming a first wave of 13 bars , the corrective also 13-1 bars. I expect most likely a third wave with 13 bars as well but could also stopped earlier at 9 bars before correction.
I'll look at bearish cross with %R , a bearish candle with a trigger. An extension up to the 161.1 level is also possible. Looking into a short opportunity with confirmation.
