Overview
Forex (foreign exchange) is the global market where currencies are traded. It is the largest and most liquid financial market in the world, with over $6 trillion traded daily. When you trade forex, you are buying one currency while selling another, speculating on how their relative values will change.
The forex market operates 24 hours a day, five days a week, across major financial centers including London, New York, Tokyo, and Sydney. This around-the-clock operation allows traders to react to news and events as they happen.
Key Concepts
Key concepts in forex include
- Currency pairs: Currencies are quoted in pairs, such as EUR/USD (euro vs US dollar). The first currency is the base, the second is the quote.
- Bid and ask: The bid is the price at which you can sell; the ask is the price at which you can buy. The difference is the spread.
- Lots: Standard lot sizes are 100,000 units of the base currency. Mini and micro lots allow smaller positions.
- Leverage: Brokers offer leverage, allowing you to control larger positions with less capital. Leverage amplifies both gains and losses.
Why Trade Forex
Forex trading appeals to many because of its liquidity, 24/5 access, and the ability to profit in both rising and falling markets. However, it carries significant risk. Beginners should start with a demo account, learn risk management, and never risk more than they can afford to lose.
