NZDUSD double top?

The Kiwi has been in an ascending channel since June, grinding higher and finding buyers on dips. Over the last couple days the NZDUSD found significant resistance at the .6800 level and now will be focusing on support at the .6600 level. A break of .6600 would trigger a double top and a measured move would be back to the .6400 level which just so happens to be the 200dma. The important thing to note should that happen is the ascending channel would be broken and the NZDUSD would be in “sell rallies” mode.
