GBPUSD waiting for sell setup

I'm waiting for break out of the trend line for several sell setups.

both directions possible, maybe upside is more likely because of divergence

הערה:

break out below (b) wave can be a trigger for short setup

I was expecting a WXY correction, but it continued for WXYXZ correction which is more complex.
Although there was no trade setup to downside, because price didn't make a correction after breaking the trendline and price never breaked below 1.43337 which i mentioned in the above chart as an entry order.
Now this corrective pattern is about to end and I expect a wave to downside will form soon.
