What Is Forex Trading?
Forex — short for foreign exchange — is the global market where currencies are bought and sold. Every time you've exchanged money at an airport or bought something from another country online, you've participated in the forex market in a small way.
But the forex market as traders know it is something much larger. It's a decentralized, over-the-counter (OTC) market that runs 24 hours a day from Sunday evening to Friday evening. There's no single exchange or building where forex trades happen. Instead, it's a network of banks, institutions, brokers, and individual traders connected electronically around the world.
The daily trading volume is staggering. According to the Bank for International Settlements (BIS), the forex market turns over roughly $7.5 trillion per day. To put that in perspective, the New York Stock Exchange handles about $25 billion per day. The forex market dwarfs every other financial market on Earth.
For retail traders — people like you and me — forex trading means speculating on the price movements of currencies through a broker. You're not physically buying euros or yen. Instead, you're entering contracts (usually CFDs) that track currency prices. If your prediction about price direction is right, you profit. If it's wrong, you lose.
How Currency Pairs Work
Currencies are always traded in pairs. You can't just "buy the euro" in isolation — you buy the euro against something else. That something else is another currency.
The most commonly traded pair in the world is EUR/USD — the euro versus the US dollar. When you see this pair quoted at, say, 1.0850, it means one euro costs 1.0850 US dollars.
Every pair has two parts:
- Base currency — the first currency (EUR in EUR/USD)
- Quote currency — the second currency (USD in EUR/USD)
If you think the base currency will get stronger relative to the quote currency, you buy the pair (go long). If you think it'll weaken, you sell (go short). That's really the core mechanic of forex trading.
Say you buy EUR/USD at 1.0850. The euro strengthens, and the price moves to 1.0950. You've just made 100 pips of profit. If the price had dropped to 1.0750 instead, you'd have lost 100 pips.
Major, Minor, and Exotic Pairs
Not all currency pairs are created equal. They fall into three categories based on how widely they're traded:
Major Pairs
The majors all include the US dollar on one side. There are seven of them:
- EUR/USD — Euro / US Dollar (the most traded pair globally)
- USD/JPY — US Dollar / Japanese Yen
- GBP/USD — British Pound / US Dollar
- USD/CHF — US Dollar / Swiss Franc
- AUD/USD — Australian Dollar / US Dollar
- USD/CAD — US Dollar / Canadian Dollar
- NZD/USD — New Zealand Dollar / US Dollar
Majors have the tightest spreads and most liquidity. They're where most beginners start, and for good reason — trading costs are lowest.
Minor Pairs (Crosses)
Minors combine major currencies but skip the US dollar. Think EUR/GBP, GBP/JPY, or AUD/NZD. They're still reasonably liquid, but spreads are wider than majors.
Exotic Pairs
Exotics pair a major currency with a currency from a developing economy: USD/TRY (Turkish lira), EUR/ZAR (South African rand), or GBP/MXN (Mexican peso). These can be wild. Wide spreads, lower liquidity, and sometimes massive overnight moves. Not recommended for beginners.
How to Read a Forex Quote
A forex quote always shows two prices: the bid and the ask.
If your broker shows EUR/USD as 1.0845 / 1.0847:
- 1.0845 is the bid — the price you get when selling
- 1.0847 is the ask — the price you pay when buying
The bid is always lower than the ask. That gap between them? That's the spread, and it's how your broker makes money on each trade.
Most currency pairs are quoted to four decimal places. Japanese yen pairs are the exception — they use two decimal places. So USD/JPY might be quoted as 149.85 / 149.87.
Some brokers show five decimal places (or three for JPY pairs). That extra digit is called a pipette, and it gives you slightly more precision.
The Bid/Ask Spread
The spread is your primary trading cost in forex. Every time you open a trade, you start in a small loss equal to the spread.
For major pairs with a competitive broker, the spread might be as low as 0.1 to 0.5 pips. For exotic pairs, it could be 5, 10, or even 30+ pips. The wider the spread, the more the price needs to move in your favor before you break even.
Spreads aren't fixed — they widen and narrow depending on market conditions. During major news releases, at the daily rollover (around 5 PM New York time), or during low-liquidity hours (like the Asian session for EUR/USD), you'll see spreads widen.
Some brokers offer fixed spreads that stay constant regardless of conditions, though these are usually wider than variable spreads during calm markets.
What's a Pip?
A pip stands for "Percentage in Point" and it's the standard unit for measuring price movements in forex. For most pairs, one pip equals 0.0001 — the fourth decimal place. For JPY pairs, it's 0.01 — the second decimal place.
If EUR/USD moves from 1.0850 to 1.0870, that's a 20-pip move.
The dollar value of a pip depends on your lot size:
- Standard lot (100,000 units): roughly $10 per pip on EUR/USD
- Mini lot (10,000 units): roughly $1 per pip
- Micro lot (1,000 units): roughly $0.10 per pip

Leverage and Margin Basics
Leverage is what makes forex trading accessible to people without millions in capital. It lets you control a large position with a relatively small deposit.
With 1:100 leverage, your $1,000 controls a $100,000 position. That's powerful, but it cuts both ways — your profits and losses are both magnified.
Margin is the money your broker holds as collateral while your leveraged trade is open. It's not a fee; you get it back when you close the trade (minus or plus your profit/loss).
Different regulators impose different leverage limits. In the EU and Australia, retail traders are capped at 1:30 for major pairs. Offshore brokers might offer 1:500 or even 1:1000. Higher leverage isn't necessarily better — it just means bigger positions and faster losses if the trade goes wrong.
If your trade moves against you badly enough, you'll hit a margin call — your broker either asks for more funds or starts closing your positions to prevent further losses.

Forex Market Hours
The forex market is open 24 hours a day, Monday through Friday. That's because there's always a major financial center open somewhere in the world. The market flows through four main sessions:
| Session | Major Center | Hours (UTC) | Character |
|---|---|---|---|
| Sydney | Sydney | 22:00 – 07:00 | Quiet, low volume |
| Tokyo (Asian) | Tokyo | 00:00 – 09:00 | JPY and AUD pairs active |
| London (European) | London | 08:00 – 17:00 | Highest volume session |
| New York (US) | New York | 13:00 – 22:00 | Strong moves, especially at overlap |
The busiest period is the London-New York overlap (13:00–17:00 UTC). That's when the most traders are active, liquidity is deepest, and the biggest moves tend to happen. Many day traders focus exclusively on these hours.
Weekends are dead — the market closes Friday evening and reopens Sunday evening. Occasionally, prices "gap" at the open if something significant happened over the weekend.
Who Trades Forex and Why?
The forex market isn't just retail traders staring at MetaTrader charts. It's a massive ecosystem with different participants:
- Central banks manage monetary policy and sometimes intervene in currency markets directly. The Bank of Japan, for instance, has a long history of stepping in when the yen moves too fast.
- Commercial banks are the backbone of the interbank market. They trade currencies for clients, manage their own positions, and provide liquidity to the rest of the market.
- Hedge funds and institutions trade currencies as part of larger strategies — whether that's carry trades, global macro bets, or currency hedging.
- Corporations use forex to manage risk from international business. A European company selling goods in the US needs to convert dollars back to euros — and wants to lock in favorable rates.
- Retail traders are individual traders using online brokers. We're a tiny fraction of the total volume (estimated at 5-6%), but our numbers have grown massively over the past two decades.
Why do retail traders get into forex? The usual reasons: low barrier to entry (you can start with $50-100 at many brokers), the ability to trade 24/5, leverage that amplifies small accounts, and the appeal of being your own boss. The reality is that most retail traders lose money — roughly 70-80% according to broker disclosures required by EU regulators. That's not meant to scare you off, just to be honest. Proper education and risk management dramatically improve your odds.
Getting Started
If you've read this far and still want to give forex a shot, here's a sensible path forward:
- Learn the basics thoroughly. You're already doing this. Make sure you understand leverage, margin, and risk before going further. Our guides on leverage and risk management are good next steps.
- Open a demo account. Every decent broker offers one. Trade with virtual money until you're consistently making decisions you're happy with. Don't rush this step — most people skip it and regret it.
- Pick a regulated broker. Regulation matters enormously. It protects your funds and ensures fair dealing. Our broker reviews can help you compare options. If you're not sure what to look for, start with our guide to choosing a broker.
- Start small. When you go live, use micro lots and risk no more than 1-2% of your account per trade. Your first goal isn't to get rich — it's to survive long enough to learn.
- Keep a trading journal. Write down every trade: why you entered, what happened, what you'd do differently. This is how you actually improve, and almost nobody does it consistently.
Forex trading isn't easy money. It's a skill that takes time, discipline, and a willingness to lose before you win. But for people who put in the work, it can be a genuinely rewarding way to engage with global markets.
