Nice graph showing dollar amount of currencies traded in the Foreign Exchange Market---Impress your econ teacher or your Professor!!

I knew lots of currencies are traded in the Foreign Exchange Market on a daily basis, but I did not know how much in dollar terms. This graph (HT: The Conversable Economist) gives a pretty good idea--in the $4 Trillion dollar range.  Nice for teachers to show students and great for students who want to impress their economics teacher!! :
