If you check most of the GBP pairs, you will notice something similar. It either broke a major or about to break.
Here is what i see.
GBP-NZD broken the to the upside.
GBP-USD is about to break the triangle.(It may retrace a little before breaking)
EUR-GBP broken the to the downside.I believe top was already in place with 8100 level.
GBP-JPY broken one and touched another one with a move.(may retrace since it's over bought)
And now GBPAUD is about to break the daily . (All these suggests pound will be ).
I will look for long trade if it;s indeed break the daily .
