Forex trading is the act of buying and selling currencies to make a profit. With about $9.5 trillion traded a day (BIS, 2025), it's the largest financial market in the world. Understanding how it works, and how traders lose money in it, comes before anything else.
What Does Forex Mean?
Forex stands for "foreign exchange." It refers to the global marketplace where currencies are traded against each other. When you exchange dollars for euros at an airport, you're participating in the forex market on a small scale.
In trading, forex involves speculating on whether one currency will rise or fall against another. Traders buy currencies they believe will strengthen and sell those they expect to weaken.
How Does Forex Trading Work?
Forex trading always involves currency pairs. You're simultaneously buying one currency and selling another. For example, in the EUR/USD pair:
- EUR is the base currency (what you're buying or selling)
- USD is the quote currency (what you're paying with)
If EUR/USD is trading at 1.1000, it means 1 euro equals 1.10 US dollars. If you believe the euro will strengthen against the dollar, you would buy EUR/USD. If correct, you profit from the price increase.
Why is Forex So Popular?
Several features make forex attractive to traders:
24-Hour Market: Unlike stocks, forex trades around the clock from Monday to Friday. This allows flexibility for traders in any timezone.
High Liquidity: The massive trading volume means you can enter and exit positions quickly at stable prices.
Low Starting Capital: Many brokers allow you to start with as little as $100, making it accessible to beginners.
Leverage: Brokers let you control positions larger than your deposit. This magnifies losses exactly as much as gains, which is why position size matters more than anything else on this list.
Two-Way Trading: You can profit whether currencies rise or fall by going long (buying) or short (selling).
