This current set of fibs was drawn July 7th using Weekly data and has highlighted a few tradeable entries over the past four months or so. This pattern remains valid until either -23.6% or 61.8% line is broken.
The ZXY and DXY currency indexes are currently moving in opposite directions after reversing from recent . I think this opposite movement - negative correlation - increases the chances of a profitable change, and at the very least gives a headsup if one of the currencies in the pair may work against the trade.
A great entry would have been the point highlighted by arrows - all three charts lined up increasing likelihood of a profitable trade on the NZDUSD .
