GBPAUD very long term (1 year) sell

GBPAUD long term sell, maybe 3500 pip drop over the next year. On the weekly time frame its formed a channel after a very big impulse to the downside. Its in a clear downtrend therefore i believe this weekly channel will break down from around the area its at now. On a closer look a smaller 4 hour channel has formed which price is at the top of and has also hit the 0.382 level signalling a point of entry for me.
