USD/JPY SHORT - Made a clear Bearish start pattern (30min chart)

You can see that the first Bearish channel got broken, but the long term decending line hasen't been broken yet.
We are waiting for a breakout "Downwards" at the support lv and then retest it before entry.
Im still kinda new Forex trader but i wanna share my idea and see what people say :)
Maybe other people have other views on it :D
