During many years Forex traders had been only stationed at the major banks, large financial institutions and most countries central banks; they didn't exist outside that cold world. But these days things have changed, we live in a different world and thanks to the internet the forex market has been totally opened to anyone willing to learn the right techniques that forex trading requires and with the intention of making substantial profits as the before mentioned institutions do. It's a fact that they consistently make pretty high profits from trading in the Foreign Exchange market. Being many times this the most profitable activity of the financial institution.
As a short introduction, the forex market has five major currencies: US Dollar, Japanese Yen, British Pound, Euro and the Swiss Franc. These five major currencies have a great popularity in world's commerce transactions due to the economic power of the countries emitting the currencies so these five currencies account for over 70% of North American trading. What this means is that you should place great attention to these currencies when trading because they will be the ones that will show the most evident trends as the markets evolve with time.
