Well, I sure like your thought AND that is quite a bit below the thought James is looking at at 1.5239 and you are looking at "next week" for those levels !!!
I have been waiting patiently for the USD to take off but so far it is still struggling.
With GPB at about 12% of USD I'm not up to speed on how it tracks [e.g. Euro is pretty inverse] so watch with interest.
And I'm all set to short that sucker when it starts to move down !!!
I would like to think that for GBP to get down to your numbers the USD will have to go up a bit and in concert Euro down, and hopefully Silver will drop as well !!
I guess we just have to wait it out ....
Have a Happy Holiday !!
