The analyst expects the correction to end when the USDX reaches a value of 101.800. This is the predicted target for the end of the "C" wave of the correction. Once the index hits 101.800 (according to this analysis), the correction is expected to be complete, and the USDX may then resume its previous (likely upward) trend.
In short: The USDX is expected to fall to 101.800 to finish a temporary price dip (correction) that's shaped like an ABC pattern.
