Currency
Currencies are the money of different countries, and currency trading is the buying and selling of these currencies. There are almost as many different currencies as there are countries, but the most popular currencies for trading are the US Dollar, the Euro, the British Pound (Sterling), and the Japanese Yen.
The currency markets are some of the most popular day trading markets, and they therefore have some of the highest volume (number of contracts) and liquidity. This high volume and liquidity makes the currency markets attractive to all types of traders, including individual day traders, trading companies, financial and non financial companies, banks, and governments
