The measured move of the double top would be confirmed by AB=CD (purple), which would lead the DXY to the base of the Ichi cloud at 0.382 FIb (June 2010 High - May 2011 Low).
Note MACD is crossing the signal line.
Independent of all the taper talk, you can see that DXY has flipped alternatively between the red channel and the yellow one quite regularly for 2 years and atm it seems that it's going to spend some vacation within the red channel, maybe as long as Ben is still with the Fed.
Should this play out, I'd expect some sort of same ranging behaviour for EUR and Cable and other USD pairs.
There's a possible 3 Drives pattern but it's too early to say.
