What Forex Is and How the Currency Market Works
Forex is the global over-the-counter market for exchanging currencies. It has no single venue and no "center" that sets the rate: price is formed by supply and demand between banks, brokers and traders. Below is how it is built and why results here are decided by a system, not by luck.
Why Forex Has No Single Exchange
Unlike the stock market, forex trades are made directly between participants through a network of electronic systems rather than on one exchange. Because of that the market runs around the clock five days a week, rolling from the Asian session into the European and then the American one.
What you see in the terminal is the aggregated quotes of liquidity providers, primarily large banks. The gap between the buy and sell price (the spread) is the main transaction cost of a trade.
| Parameter | How it works on forex |
|---|---|
| Venue | None — an over-the-counter (OTC) market |
| Trading hours | Around the clock, 5 days a week |
| Source of price | Quotes from banks and liquidity providers |
| Trader access | Through a broker, usually with leverage |
How a Trader Reaches the Market
A retail trader operates through an intermediary broker, which usually provides leverage. Leverage magnifies both profit and loss proportionally — and it is leverage, not the "complexity of the market," that most often wipes out a beginner's deposit so quickly.
- A trading system with rules
- Managing risk per trade
- Discipline in execution
- Guessing the direction
- Maximum leverage
- Chasing losses back
In brief
- Forex is over-the-counter: there is no single exchange and no "official" rate.
- Price is the aggregated quotes of banks; the spread is the main cost of a trade.
- Leverage magnifies profit and loss symmetrically — it is the main source of risk.
- Durable results come from a systematic approach and risk management, not from guessing.
