Dollar is down today...UUP
I believe today's rise e.g. in Euro vs USD is an inflection, a short-term counter-rally. Conceivably fallout from Germany's naked short law: I'm not competent to judge.
However the trend in (for instance) Euro vs USD in one of those trends you can 'see across the room'. Those are the trends we can take to the bank, and which dollar-shorters watch with great fear. Gold, Silver and the resource-backed CAD rise month on month against USD: other currencies tend to fall.
As far as I can tell, inflection points on a downtrend trend are the time to divest. Perhaps because you can more easily find buyers and a better price.
