http://www.all-forex.net/trade-at-forex-with-opteck/ The Forex market is the largest financial market on Earth. Its average daily trading volume is more than $3.2 trillion. Compare that with the New York Stock Exchange, which only has an average daily trading volume of $55 billion. In fact, if you were to put ALL of the world's equity and futures markets together, their combined trading volume would only equal a QUARTER of the Forex market. Why is size important? Because there are so many buyers and sellers that transaction prices are kept low.
