The software package of currencies allow you to choose between 40 and 70 different currencies, though, in reality, roughly 180 pairs exist. You won’t need to access that many different currencies in any year. The country fiats that you can buy and sell, however, are based on the broker you work with. Like all self-directed investments, you won’t need a broker’s help as you enter and exit positions. Still, you do need to understand how to masterfully use software.
