This is breaking through a big weekly support level. Best time to enter a short is on a retest of the support now acting as resistance. This will give the safest trade setup, for a SL the highest previous point is too high for a good risk/reward ratio so it can be just above 0.618 Fib. TP is at the next support level downwards.
As I said best entry is to wait for a retest and rejection from the new resistance (previous support).
