The U.S. Dollar Index has broken above 81 and this is the first good bullish sign. Short-term resistance is found at 81.30 and at 81.50 as shown in the 4 hour chart below. Breaking above these levels will be bullish for the intermediate-term trend and it gives us 82.5 as the first target.
If the 81.50 high is achieved, then long-term bulls should use 79.70 as a stop. Target for longer term traders is 85. Short-term resistance is at 81.30 and short-term trend will change if prices break below 80.85.
The decline from 81.50 to 79.70 is a corrective pattern. The rise from 79 to 81.50 is impulsive. This implies that more upside might be expected. Confirmation will come if prices break above the blue resistance area.
