What Is Forex: The Global Market That Never Sleeps

Risk warning: Forex trading carries high risk. You can lose all the money you put in. This article teaches how the market works. It is education, not financial advice. Only trade with money you can afford to lose.

Forex means "foreign exchange". It is the act of changing one currency into another.

When you travel from Lagos to London and change your ₦ (naira) into £ (pound), you take part in forex. But most forex trading is not travel money. Banks, companies, and everyday people buy and sell currencies to profit from price changes.

The market never sleeps

The forex market opens on Monday morning in Sydney. It then moves through Tokyo, London, and New York. When New York closes, Sydney opens again. This cycle runs 24 hours a day, 5 days a week.

From Nigeria (WAT, West Africa Time), the busy sessions fall in your day and evening. London runs roughly 8am to 5pm WAT. New York runs roughly 1pm to 10pm WAT. So the most active hours are your afternoon and evening.

Why do people trade forex?

Currencies move up and down every day. A trader tries to buy a currency low and sell it high.

Example: if $1 = ₦1,500 today and $1 = ₦1,550 tomorrow, a trader who bought dollars made a small profit.

A warning before you start

Forex is risky. Prices can move fast. Many beginners lose money. Never borrow money to trade. Never use money you need for rent, food, or school fees.
