EURGBP : SHORT THE PULLBACK

The price makes lower low and breaks the neckline near 0.85970, so I am interested to sell the pullback, and the price i want to short will be near 0.85930-0.86050, where FIBO 0.50, and small AB=CD converge at there, and also the structure resistance of neckline.
TRADE IDEA :
SELL AT NEAR 0.85970-0.86050
SL : 0.86300
TP : 0.84853
