<human>: Hi Reddit,

I was just wondering, what affects currency exchange rates and how is it set? I'm from Canada, so taking a look at the CAD/USD exchange rate, Ive been watching it for the past few weeks and it's always around USD/CAD 1.078 to 1.02, but I have no idea what makes it go up and down.

My second related question is, after learning what makes it go up and down, are there people who can gauge what will happen tomorrow? next week? in the foreseeable future? If so, does it take many years of experience and education, or can mr. joe blow (with enough patience and self-education) be able to make certain claims and be accurate?

Provide a brief overview of the text.
