that's all I am trading right now, USD. It's the one currency I am not afraid to be 100% long or 100% short. I fell asleep Fri am at 8:00 100% short USD, and woke up and still didn't make any money because I got stopped out too many times on the chop. I was flat AUD and went short at the very bottom, got stopped out and went long at the very top. (and this was all why I was asleep due to some stop loss and some stop to add open orders.)
The heck with it, I'm going into the weekend flat the aud and long a full load of eur.usd (and long a full load of usd.cad), so that makes me long eur.cad, and I don't care what the dollar does right now. But I'd sure like to get out of this long eur as soon as possible. 1.10 is the magnet. I see it as the price where Greece (no matter what) is already priced in. Who knows? If the fed doesn't do something soon will they start trashing the dollar? I don't know, but I see the dollar as the most stable currency out there right now, if you are looking for a good stable currency to trade against. And just a month ago I was trading against the eur because I thought it was the most unstable. I guess it just depends on what you are looking for.
