What Is Forex Trading? (And Should You Try It?)

You're trading one currency against another

Forex is short for "foreign exchange." When you trade forex, you're always dealing with a pair of currencies. EUR/USD, for example, means you're looking at the euro versus the US dollar. If you buy EUR/USD, you're betting the euro will get stronger relative to the dollar. If you sell, you're betting the dollar will win.

You've actually done forex before without realizing it. If you've ever traveled to another country and exchanged your dollars for euros or yen at the airport, that was a forex transaction. You were buying one currency and selling another. The exchange rate told you how much you'd get.

The difference between that airport exchange and forex trading is scale and speed. Forex traders are doing thousands of these exchanges per day, trying to profit from tiny price movements in currency pairs. A one-cent move in EUR/USD doesn't sound like much, but with enough volume, it adds up fast.

It's the biggest financial market on Earth

About $7.5 trillion changes hands in the forex market every single day. That number is hard to wrap your head around, so here's some context. The entire US stock market trades roughly $500 billion per day. The forex market is about 15 times larger.

Why is it so big? Because every international business transaction involves currency exchange. When Toyota sells cars in America, they eventually need to convert dollars back to yen. When a European pension fund buys US Treasury bonds, they need dollars. All of that flows through the forex market.

For individual traders, the sheer size of the market means high liquidity. You can almost always get in and out of a trade quickly because there's always someone on the other side. That's one of the things that attracts people to forex. Getting stuck in a position because no one wants to buy is rarely a problem.

The 24-hour market

Unlike the stock market, forex doesn't close at 4pm. It trades around the clock from Sunday evening to Friday evening (US Eastern time). The market rolls through four major sessions: Sydney opens first, then Tokyo, then London, then New York. As one session winds down, the next one picks up.

The busiest hours are when sessions overlap. The London-New York overlap (roughly 8am to noon Eastern) is when you'll see the most volume and the tightest spreads on major pairs. The Tokyo-London overlap is another active window, especially for yen pairs.

This 24-hour schedule is a double-edged sword. It means you can trade whenever it fits your schedule, even at 3am. But it also means prices can move significantly while you're sleeping. You might go to bed with EUR/USD at 1.0800 and wake up to 1.0750 because of something that happened during the Asian session.

Why beginners often lose money in forex

Most retail forex traders lose money. That's not an opinion. Brokers are required to disclose these numbers, and they consistently show that 70-80% of retail forex accounts are unprofitable. There are a few reasons why.

The biggest one is leverage. Forex brokers let you control large positions with a small amount of money. You might put up $1,000 but control $50,000 or even $100,000 worth of currency. When the trade goes your way, the profits are amplified. When it goes against you, the losses are amplified by the same factor. A 1% move against a 50:1 leveraged position wipes out half your account.

The second reason is overtrading. Because the market is open 24 hours, there's always a temptation to place "just one more trade." Beginners often end up taking low-quality setups out of boredom or the desire to recover losses. This compounds into a slow bleed of the account balance.

Practice forex in a simulator first

Given the statistics above, jumping into live forex trading with real money is not a great first move. A simulator lets you trade currency pairs at real prices with fake money, so you can learn the rhythm of the market without risking anything.

Watch what happens to EUR/USD during a Federal Reserve interest rate announcement. See how USD/JPY moves overnight during the Tokyo session. Try holding a position for a few days and notice how much it fluctuates. These experiences will give you a gut-level understanding of forex that no textbook can provide.

Stock Academy includes forex pairs alongside stocks and crypto, so you can compare how all three asset classes behave. You might find that you prefer the slow, steady movement of major currency pairs over the wild swings of crypto. Or you might decide forex isn't for you. Either answer is valuable, and you'll get it without spending a dollar.
