People do Forex trading all the time; they just don’t realize it. If you are an American citizen and you take a trip to
Europe
somewhere as a vacation, chances are you will be doing Forex trading at some point. You take your American currency and then either in the
United States
before you leave or alternatively in
Europe
wherever you end up staying you will exchange that American currency for European currency to allow you to spend it without losing a lot of money at the poor exchange rates offered by most merchants. Then, whatever European currency you have left will get changed back to American currency when you return to the country. Whether you realize it or not, you have just conducted a Forex transaction.
