I have new idea based on the new trend on GBP. I post my long-term view of GBP in 2018, now it still works. Price reach 7(see in the link), but doesn't move higher now. So I think GBP will move down a little and then you will get a better price to buy it.
*Now bat pattern is in your eyes. B is 50% retracement of XA and D is 88.6% retracement as well as 2 times of BC. Hence potential reversal zone is around 1.3580.
* stop loss:1.3625 target:1.3400
*Also if GBP fall into the target area, you can buy it!
