GBPJPY H4: Short setup trading plan

GBPJPY is on a pretty heavy corrective movements and has a chance to form a Bearish Gartley harmonic pattern. I will wait a confirmation on entry area to go short. However because it's pretty risky, I am preparing to change the plan and go long if there's an impulsive bullish movement occurred on the entry area (134.50).

Entry: 134.50
TP 1: 133.35 (RR 1:1.9)
TP 2: 132.50 (RR 1:3.3)
SL: 135.10
