On the 4h chart of USD Index we have seen a deep decline over the past few months, which is seen as a corrective move, but still unfolding after that gap down to 99.10.

An updated structure and recent activity suggests that downward movement is underway in wave C) of four and is looking for a low near 98.00/98.50. We would need a new impulsive bounce to confirm a low in place.
