too clear short timing(rising wedge)

this chart show us too clear rising wedge.
this indicate price will go down.

i short 50k at 45k.
stop loss 45500(previous high prise in 4h chart).
ta 1 -> 40k (10%) (3k below parallel channel)
ta 2 -> 37k (20%) (6k below parallel channel)

if price above 45500, then i think price can go 48k.
I think it will probably be difficult.
