All forex trades involve two currencies because you're betting on the value of a currency against another. Think of EUR/USD, the most-traded currency pair in the world. EUR, the first currency in the pair, is the base, and USD, the second, is the counter. When you see a price quoted on your platform, that price is how much one euro is worth in US dollars. You always see two prices because one is the buy price and one is the sell. The difference between the two is the spread. When you click buy or sell, you are buying or selling the first currency in the pair.
Traders are people who work on the Forex market, trying to ascertain the direction in which the value of a currency will go and make a trade for the purchase or sale of that currency. As such, by buying a currency cheaper and selling it for more, traders earn money on the Forex market. Traders make their decisions based on the analysis of all factors that can affect prices; allowing them to work out precisely in which direction prices are moving. You can make a profit on the Forex market when the value of a currency drops as well as when it increases. Furthermore, traders can make trades on the Forex market from anywhere in the world; from London to Timbuktu.
Forex traders should proceed with caution, because currency trades often involve high leverage rates of 1000 to 1. While this ratio offers tantalizing profit opportunities, it comes with an investor's risk of losing an entire investment on a single trade. In fact, a 2014 Citibank study found that just 30% of retail forex traders break even or better. But tellingly, 84% of those polled believe they can make money in the forex market. The chief takeaway: new forex investors should open accounts with firms that offer demo platforms, that let them make mock forex trades and tally imaginary gains and losses, until investors become seasoned enough to confidently trade for real.
Major Currency — currencies from the world’s most developed economies including Europe, Japan, Canada, and Australia — represent the most heavily traded and liquid currency markets for any forex trader. A major currency pair is created when one of these currencies is traded against the U.S. dollar. Examples include Euro vs. the U.S. Dollar (EUR/USD) and the U.S. Dollar vs. the Canadian Dollar (USD/CAD). Their availability on a forex brokerage is essential.
