US index is being controlled and it will not fall that easily. The price movements for the past 2022 looks to me like they were all happened by either greedy or panic trades. At this moment, 50bps rate hike should pump the US index up a bit in the coming weeks.
Until around Q2-Q3 of 2023, this should be the time when USDX starts falling.
This is only my opinion and not a financial advice. Trade safe!
