USDX plunged in Wednesday's session and it's testing the support level of 102.55. However, the general structure is still choppy and one could expect another bearish leg towards the 102.08 level. In the alternative scenario, if we see a rebound at the current stage, the index is likely to resume the overall bullish bias to post new multi-year highs.
