At time of writing, the Dutch-based brokerage Saxo Bank offered more than 180 different currency pairs on its platform. This is more than just a bragging right. The foreign currency market is dominated by a handful of pairs. In fact most trading in this space occurs between just four pairs, known as the “major” pairs. (They are, in no particular order: USD/EUR, USD/GBP, USD/JPY and USD/CHF.) As a result, many currency brokerages tend to build their offerings around these four major pairs, as well as a handful of other currencies that dominate the rest of the market.
