I really don't think the dollar is going lower here. We've largely been moving sideway for the past 6 months consolidating.
You'll see on the chart that price action in January fell below key support. Then after that we rallied and tested the 200 DMA 3 times and have also retested support 3 times and haven't broken through. Now that price action is well above support, I think the next big move is up through the 200DMA.
The only way the dollar is going lower is if it breaks that key support. And I think we need to see a higher dollar before that support is broken.
I bought a lot of $30 UUP calls for September to express this view.
