Forex
a.k.a. FX, Foreign exchange, Currency trading
The global market where currencies are traded against each other, open 24 hours a day, five days a week.
Forex (short for foreign exchange, also called FX) is where one currency gets swapped for another. If you have ever changed money at an airport kiosk and winced at the rate, congratulations: you have already traded forex. You just did it badly.
There is no single building where it happens. Forex is a sprawling web of banks, brokers, companies and traders, all wired together and haggling non-stop. The market wakes in Sydney, rolls through Tokyo and London, and roars into New York before going round again. It only goes quiet at the weekend.
Traders do not buy currencies to stuff in a drawer. They bet on how one currency will move against another, always in a currency pair like EUR/USD. Guess right and the exchange rate pays you. Guess wrong and it bites. With leverage in the mix, that bite can be a big one.
An airport swap, the forex way
- EUR/USD is quoted at 1.0850, so 1 euro buys 1.0850 US dollars.
- You swap 500 euros: 500 × 1.0850 = 542.50 dollars.
- A week later the rate is 1.0900. Those 500 euros would now fetch 545.00 dollars.
Bottom line: The euro got 2.50 dollars stronger on your 500. That move, scaled up, is what forex traders chase.
Thinking forex is a shortcut to quick money. It is a skill market, and the people on the other side of your trade have been practising for years.
