For how long can we buy USD?

I have been riding trend for several months and wonder if this trend shows sign of correction? Or do I keep buying dollar and sell euro?

That is a very broad question. What does your own system say? What is your target? What can happen from here per your system? Where in the whole trading cycle does your system say you are?

[I][B]Per my methods.[/B][/I] I would not hold a buy short term, but you can hold it long term if you want.
