What Is Forex Trading?

Every day, roughly $6.6 trillion worth of currencies change hands on the foreign exchange market. That's trillion with a T — more than the combined daily volume of every stock exchange on the planet. And most people have never heard of it.

Forex — short for foreign exchange — is the global marketplace where currencies are bought and sold. When you exchange dollars for euros at the airport, you're participating in forex (at terrible rates, but still). When a Japanese car manufacturer converts its dollar revenue back to yen, that's forex too. When hedge funds bet on the British pound weakening after a political shock, that's forex at scale.

How the Forex Market Actually Works

Unlike the New York Stock Exchange or NASDAQ, forex has no central building, no opening bell, no closing bell. It's an over-the-counter (OTC) market, which means trades happen directly between participants through electronic networks.

The market runs 24 hours a day, five days a week. It follows the sun around the globe through four major trading sessions:

• Sydney session (10 PM – 7 AM GMT) — relatively quiet, mostly AUD and NZD pairs
• Tokyo session (12 AM – 9 AM GMT) — JPY pairs become active
• London session (8 AM – 5 PM GMT) — the busiest session, roughly 35% of all forex volume
• New York session (1 PM – 10 PM GMT) — USD pairs dominate, overlap with London creates peak volatility

This 24/5 structure means you can trade at 3 AM or 3 PM — whatever suits your schedule. That's one reason forex attracts people who work full-time jobs and want to trade on the side.

Who Trades Forex?

When people picture forex trading, they tend to imagine someone staring at six monitors in a dark room. In reality, the market has a wide mix of participants:

Central banks are the heavyweights. The Federal Reserve, European Central Bank, Bank of Japan — they influence currency values through interest rate decisions and monetary policy. When the Fed raises rates, the dollar typically strengthens. Their moves ripple through the entire market.

Commercial banks make up the bulk of daily volume. Deutsche Bank, JP Morgan, Citibank — these institutions trade currencies for their clients and for their own profit. The interbank market, where banks trade with each other, sets the exchange rates you see on your screen.

Hedge funds and institutional investors trade forex to profit from currency movements or to hedge their international portfolios. George Soros famously made $1 billion in a single day betting against the British pound in 1992.

Corporations use forex for practical purposes. If Toyota sells cars in the US but pays workers in Japan, it needs to convert USD to JPY regularly. These hedging transactions are a big part of market activity.

Retail traders — that's you and me. Individual traders account for roughly 5-6% of total forex volume. That might sound small, but 5% of $6.6 trillion is still $330+ billion daily. Retail trading has exploded since online brokers made it accessible with accounts as small as $50.

Why People Trade Forex

Several characteristics make forex attractive compared to other markets:

Liquidity. The sheer volume means you can almost always find a buyer or seller. In major pairs like EUR/USD, you can enter and exit positions of practically any size without moving the market. Try doing that with a small-cap stock.

Low barriers to entry. You can open a forex account with as little as $10-50 at many brokers. Compare that to futures (often $5,000+ minimum) or the pattern day trading rule in US stocks ($25,000 minimum for active trading).

Leverage. Forex brokers let you control large positions with relatively small deposits. A $1,000 account with 1:100 leverage can control $100,000 worth of currency. This is a double-edged sword — it amplifies both profits and losses — but it means forex is accessible to smaller accounts.

Flexibility. Markets open 24 hours. You can go long or short equally easily. There's no uptick rule, no waiting for borrows. If you think the euro is going to fall, you sell it. Simple.

Low costs. Most forex brokers charge no commission on standard accounts — they make money on the spread (the difference between buy and sell prices). On major pairs, that spread can be as low as 0.1-0.5 pips, which translates to just a few cents per micro lot traded.

Common Misconceptions

Let's clear up a few things that trip people up.

"Forex is gambling." It can be — if you trade randomly with no plan, no risk management, and no idea what you're doing. But the same applies to stock trading or any other market. Professional forex traders use well-defined strategies, strict risk controls, and treat it like a business. The difference between trading and gambling is a plan.

"You need a lot of money to start." You don't. Micro and nano lots let you trade with tiny position sizes. A $200 account trading micro lots (0.01) risks about $1 per 10-pip move. That's plenty for learning. The goal when starting out isn't to make money — it's to learn without blowing your account.

"Most forex traders lose money." This one is actually true — studies show that 70-80% of retail forex traders lose money. But that statistic includes everyone who opens an account, trades recklessly for two weeks, and quits. The people who take time to learn, practice on demo accounts, and respect risk management have much better odds. The dropout rate is high because most people aren't willing to put in the work.

"You can get rich quick." No. Anyone promising you guaranteed returns or a "secret system" that makes 50% per month is either lying or selling you something. Professional traders are happy with 1-3% monthly returns on their capital. That might sound modest, but compounded over years, it builds real wealth.

What You'll Need to Get Started

Getting into forex trading doesn't require expensive software or a finance degree. Here's the basic checklist:

• A computer or smartphone with internet access
• A forex broker account (we'll cover how to pick one in Lesson 6)
• A trading platform — usually MT4 or MT5, which are free
• Starting capital — even $50-100 is enough for a micro account
• Patience and willingness to learn

Before you put any real money at risk, you should spend time on a demo account. Every reputable broker offers one with virtual funds so you can practice without consequences. Think of it like a flight simulator — you wouldn't skip that before flying a real plane.

In the next lesson, we'll break down how currency pairs work — the fundamental unit of forex trading. You'll learn the difference between majors, minors, and exotics, and understand what it actually means when you "buy EUR/USD."
