Dapanz1,
My impression is that there is a lot that goes into the valuation of a currency and so this is why I cautioned about the political comments. I didn't want a lame comment like, "because Bush is leaving office." That comment is lame, because since we don't know who will be taking his place, it actually suggests an unstable gov't. Usually, the currency of an unstable gov't declines.
I think the value of a currency is based on history, fundamentals, track records, inflation, gov't stability, type of gov't, interest rates, current state of one's economy, size of one's military, overall value of assets within a country, GDP, jobless rate, future prospects, population, balance of trade, ability to weather economic storms and much much more.
Surely some factors are more important than others so I could see a group of economists debating over which are more important. I can also see that the top 5 factors aren't always in the same order or for that matter the same factors.
How they decide on any given day that the dollar is worth more than the pound or the euro is beyond me.
Whatever the factors are at any given time, looking at charts, it seems currencies, like the stock market, go up for a time and then goes down for a time so.... cyclical. Traders ride the wave. How do you decide which currency to buy?

Were you riding the wave too?
Question: You are paid in dollars so if the dollar is going up, you really can't play in the forex now, true? I mean, you can't buy dollars with dollars and you aren't going to buy Pounds and Euros right now.
