USDJPY Short. Double Bottom but still favours downside

Updated
USDJPY 60m. There is a Double Bottom now but the bearish move has already went much below 50%. Several bear spikes and failed bull attempts to go up on 60m. My target for a short here is the beginning of the prior bull channel and then a test of the longer-term trend line.
