- 01What is forex trading?Forex trading is exchanging one currency for another, either because a business needs the currency or to profit from a change in the exchange rate. Prices are quoted in pairs such as EUR/USD, with a bid to sell at and an ask to buy at. Forex turnover averaged $9.5 trillion a day in April 2025.
- 02What is traded in the forex market?The forex market trades currencies, always two at a time: every deal buys one and pays with another. Eight are known as the majors, and the US dollar was on one side of 89% of turnover in April 2025. A retail trader receives no currency and instead holds a cash-settled contract with a broker.
- 03How does buying and selling a currency pair work?Buying a currency pair buys the first currency and sells the second, so you gain if the price rises. Selling does the opposite and gains if it falls. A buy opens at the ask and closes at the bid, and a sell does the reverse. Profit and loss land in the quote currency.
- 04How big is the forex market, and what is liquidity?Forex turnover averaged $9.5 trillion a day in April 2025, in the final results of the BIS Triennial Survey. The figure adds up the face value of new deals. Liquidity is how easily you can trade without moving the price. In AutoFXRebate's measurements, EUR/USD spreads held steady through the sessions and widened sharply at the daily rollover.
- 05Ways to trade forex: spot, forwards, swaps, futures, options and CFDs.Currencies change hands as spot deals, outright forwards, FX swaps, currency swaps, options and futures. Spot settles within two business days, a forward fixes a rate for a later date, and an FX swap pairs an exchange now with its reverse later. Retail traders usually trade CFDs or rolling spot, cash-settled contracts with a broker.
