What is forex trading?
Forex is the market where currencies are exchanged. This guide explains how a trade works, what moves a price, and what the risks are — in plain language, with no jargon left unexplained.
Forex trading is buying one currency while selling another at the same time. Currencies are always quoted in pairs, like EUR/USD. If you buy EUR/USD, you profit when the euro strengthens against the dollar, and lose when it weakens.
It is the largest financial market in the world, and it runs 24 hours a day from Sunday evening to Friday evening.
Forex in one simple idea
Forex stands for foreign exchange. Every time money changes from one currency into another, that is a forex transaction — whether it is a bank moving billions or you changing euros for dollars before a trip.
What makes it a market is that those exchange rates move constantly. A trader is not exchanging money to spend it; they are trying to profit from the movement itself.
Because currencies are always priced against each other, you never trade one currency alone. You trade the relationship between two.
EUR/USD at 1.0850 means one euro costs 1.0850 US dollars.
And because every trade has two sides, you can profit in both directions:
Pips and spreads, visually
Every pair shows two prices at once. The bid is what you get if you sell, the ask is what you pay if you buy. The gap between them is the spread, and it is the main cost of the trade.
What is a pip?
A pip is the smallest standard move in a currency pair — the fourth decimal place for most pairs, so 0.0001. If EUR/USD goes from 1.0850 to 1.0851, that is one pip.
Pips are how traders measure both profit and cost. On a standard lot, one pip is roughly $10; on a micro lot, about $0.10.
What is a spread?
The spread is the difference between bid and ask. A tighter spread means a cheaper trade. Spreads widen when the market is volatile or thin — overnight, or seconds before a major economic release.
This is why the account type you choose matters more than most beginners expect: on an active strategy, the spread is paid on every single trade.
See real spreads before you commit
A free demo account uses live market prices with virtual money. You can watch how spreads move through the day without risking anything.
A market that never really closes
Forex has no central exchange. It runs across a chain of financial centres, so as one closes another opens. That is why it trades 24 hours a day, five days a week.
The sessions are not equal. When London and New York overlap, volume peaks and spreads are usually at their tightest. In the quiet hours between New York closing and Tokyo opening, the opposite is true.
London and New York overlap between 13:00 and 17:00 UTC — the busiest window of the day.
Leverage changes the exposure
Leverage lets you control a position larger than your deposit. With 1:100 leverage, $100 controls $10,000 of currency.
The part beginners miss is that leverage does not increase your edge — it increases the size of every outcome. The same 1% market move becomes a very different event depending on how much leverage sits behind it.
In the high-leverage column, a single 1% move against the position wipes out the entire account. This is not a rare scenario — 1% daily ranges are ordinary in forex. Choose your leverage so that an ordinary day can never take you out of the game.
Major, minor and exotic pairs
Not every pair behaves the same way. They fall into three groups, and the group tells you a lot about what to expect from spreads and volatility.
- Majors — all include the US dollar: EUR/USD, GBP/USD, USD/JPY, USD/CHF. Highest volume, tightest spreads, most predictable behaviour. Where most beginners should start.
- Minors — major currencies without the dollar: EUR/GBP, EUR/JPY, GBP/JPY. Still liquid, but spreads are wider and moves can be sharper.
- Exotics — a major paired with a smaller economy: USD/TRY, USD/ZAR, EUR/TRY. Wide spreads, thin liquidity, and prone to violent moves on political news.
Beyond currencies, most brokers also offer indices, metals, energies and crypto from the same account, which is why many traders never trade forex exclusively.
What you actually need to begin
Three things: a broker, a platform, and a method for deciding when to enter and exit. The first two take minutes. The third is the work.
- A broker — the company that gives you market access. Compare spreads during real market hours, not the number on the homepage, and test a withdrawal with a small amount before funding seriously.
- A platform — where you place trades. TradeLocker runs in a browser with nothing to install; MetaTrader 5 is the standard if you need automated strategies or custom indicators.
- A demo account — live prices, virtual money. There is no reason to learn the mechanics with real capital at risk.
When you do go live, position sizing matters more than picking the right direction — these five rules cover most of what protects a new account:
Before your first live trade
- Always use a stop loss — on every trade, without exception.
- Risk 1–2% of the account per trade at most, so no single loss changes the plan.
- Start with major pairs — tighter spreads, steadier behaviour.
- Keep leverage low while learning, whatever the account allows.
- Keep a trading journal — it is the only reliable way to see what actually works.
Start with a demo, move to live when you are ready
Both run from the same HeroFX account, on TradeLocker and MetaTrader 5. Raw spreads from −0.4 pips, and withdrawals in crypto.
Key takeaways
- Forex is always traded in pairs — you are buying one currency and selling another simultaneously.
- The spread is the cost of every trade, so it compounds with how often you trade.
- Leverage multiplies both directions equally — treat it as the first risk setting you control.
- Majors have the tightest spreads and the most predictable behaviour — start there.
- A demo account removes every reason to learn the mechanics with real money.
Forex vs other markets
Forex is not the only market a broker gives you access to. This is how it compares with stocks and crypto on the things that change how you trade:
| Feature | Forex | Stocks | Crypto |
|---|---|---|---|
| Trading hours | 24/5 | Exchange hours only | 24/7 |
| Liquidity | Very high | High | Medium |
| Leverage available | Up to 1:500 | 1:30 | 1:30 |
| Minimum to start | Very low | Varies | Very low |
| Volatility | Medium | Medium | Very high |
At HeroFX all three trade from the same account — see the full markets list.
Forex trading FAQs
How much money do I need to start forex trading?
Less than most people assume. Many brokers, HeroFX included, let you fund an account from $5 with crypto. The more useful question is how much you can afford to lose while you learn — and the answer for most beginners is to start on a free demo account with no money at all.
Is forex trading profitable?
It can be, but it is a skill with a real learning curve — consistent results come from risk management, position sizing and discipline far more than from predicting the market. Treat any promise of guaranteed returns as a warning sign, and give yourself time on a demo before real capital is involved.
What is the best currency pair for beginners?
EUR/USD. It has the highest volume of any pair, which means the tightest spreads and the fewest surprise moves. Exotic pairs look tempting because they move more, but wide spreads and thin liquidity make them unforgiving.
What leverage should a beginner use?
As little as possible while you learn — 1:10 or lower keeps a normal daily move from doing serious damage, as the comparison above shows. Brokers may offer far more (HeroFX goes up to 1:500), but offered and advisable are different things: professional traders typically use a fraction of what is available. Increase it only when your results on low leverage justify it.
Do I need to understand economics to trade forex?
Not in depth, but you should know what moves prices: interest rate decisions, inflation data, employment figures and political events. Knowing when a major release is due matters more than being able to forecast it.
Can I trade forex with a full-time job?
Yes — this is one of the practical advantages of a 24-hour market. Traders in Europe often work the London session, while those elsewhere use the Asian or New York sessions. What matters is trading a session you can actually be present for, consistently.
