After having missed an 81.56 rally target by just 0.22 points, the Dollar Index has plunged by nearly a full point. The pullback would become bearishly impulsive on the hourly chart if it hits 80.18 today, but there’s no point drawing any conclusions until that happens.  The decline has already exceeded 50% of the rally from last Wednesday’s low, but support at 80.24, where 0.618 Fibo line comes into play, remains to be tested.
