At the H1 chart, the USDX is forming a higher high pattern below the resistance level of 99.22, as we're expecting more upside moves in the coming days. We should note that the support zone of 98.79 could be strong in a short-term basis, because it's in the 200 SMA price zone. This scenario should be invalidated when the Index breaks the 98.39 level.

H1 chart's resistance levels: 99.22 / 99.49

H1 chart's support levels: 98.79 / 98.39

Trading recommendations for today: Based on the H1 chart, place buy (long) orders only if the USD Index breaks with a bullish candlestick; the resistance level is at 99.22, take profit is at 99.49, and stop loss is at 98.94.
