Moment of truth for GBPUSD

I am looking that GBPUSD is on a strong downtrend but it is trying to re-test the highs of the channel. It is making a nice rebound from the lower part of the Bollinger band so if it breaks the channel, we may see a long uptrend.

Let's see, I am adding a SHORT if it fails to break the channel but most likely scenario will be it will go up.
