This is an interesting setup. UJ is highly likely the first part of a five wave impulse corrective structure that ends as an ending diagonal. These can be very long, very boring and are the bottom-pickers' nightmare. Suggested bottoms indicated to the left.
However; One target is reached already.
Was the 1.618 target extension "it"? If it leaves the channel, most likely yes. If no, try again. Looking to the long UJ rally upwards, I think itwill spend a lot of time going down in narrow range and less time try to fly around. Here the rule is to short all highs within the channel. Reasonable SL is recommended.
