CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. Excess volatility increases risk further. Be cautious. Past performance is not an indication of future results.

What is forex, and why does every rate arrive as two figures? · Taiwan

The screen shows two numbers for one currency pair, and beginners read that as a quirk of the platform. It is not: it follows from what this market is.

Forex — short for «foreign exchange» — is the global market where one currency is swapped for another, euros for US dollars. There is no building, no opening bell and no institution that prints an official rate for the day. A rate is not published; it is offered, by somebody prepared to take the other side of the swap right then. And an offer always answers two separate questions — what will be paid to acquire the currency, and what will be paid out to part with it — so it arrives as two figures rather than one. Everything a trade costs to open begins there.

Where the second figure comes from

A swap has two sides, so a quote has two prices

Picture the smallest possible version: two people, one wants euros and holds dollars, the other holds euros and wants dollars. Nothing about that arrangement produces a single agreed number by itself. Each is answering a different question, and the two answers are never identical — if they were, neither side would have any reason to be in the business of standing there ready to swap.

Scale that up to banks, companies and travellers in every time zone, all doing it continuously, and the shape survives intact. What reaches a trading screen is the best offer available at that second in each direction: a higher figure to buy at, a lower figure to sell at. The distance between them is not a fee somebody added to the market — it is the market, seen from a position where you must deal at one end of it or the other.

That is also why the distance is a live number rather than a price-list entry: it depends on how much is standing ready to be swapped at that second, and that quantity is never constant. Whichever direction an order takes, it meets one end of the offer and not the middle. What that comes to in practice, hour by hour, is the subject of the front page of this site.

Reading the pair itself

Two currencies in one price, and which one is being priced

A price always names two currencies, because a currency has no price except in terms of another one. EUR/USD is the price of one euro in US dollars: at 1.1000, a euro costs a dollar and ten cents. The first currency is the one being priced; the second is doing the pricing. When the number rises the euro has become more expensive against the dollar, and when it falls, cheaper.

Both quoted figures are written this way, and that is the practical reason to have it straight. Buying the pair means acquiring the first currency and paying with the second, so the order meets the higher of the two figures; selling it first does the reverse and meets the lower. Direction decides which end of the offer is yours before anything else about the trade is settled.

Sizes are conventions, not opinions

What stays the same wherever the swapping happens

Shapelessness stops at the numbers. 1 lot, the standard size, is 100,000 units of the first currency, and nobody starts there: 0.01 lot is a hundredth of it. A pip — 1.1000 becoming 1.1001 — is worth about 10 cents at that smaller size and around $10 on a full standard lot of most US-dollar pairs. A Standard Cent account keeps the balance in cents and trades roughly a hundred times smaller again.

Those conventions are what make a quoted distance convertible into money. A gap of so many pips means nothing until a size is attached to it, and attaching one is arithmetic anybody can do before an order exists — it is worked step by step on the practice calculator, and the four checks that use it are in start here.

The stretch with no offers

What the weekly pause actually pauses

Weekday trading runs 24 hours a day: desks finishing in one part of the world hand on to desks opening in another, and there is nothing to shut because there was never a door. Once a week the last of them finish with nobody opening behind them, and the swapping stops.

What that pause removes is not a building's opening hours but the offers themselves. With nobody standing ready, there is no figure to deal at — which is why an order cannot be filled across it, and why the first quote of the new week need not continue from the last one of the old. Two days of news arrive with the first swaps at the restart.

Getting to it

Reaching a market that lives nowhere

An account is opened with a broker — the company that connects a person to those offers and relays them — and the nearest thing to a trading floor is a program on a device: MetaTrader, or the Exness Terminal. Exness has operated as a global multi-asset broker since 2008, with more than 100 instruments across forex, metals, energies, stocks and indices.

What arrives that way is not the swap itself. Everyday traders rarely own the currencies at all: they hold a CFD that follows the pair, which is a separate contract with its own written terms. What a broker does and does not do is set out in what a broker does.

The honest part: understanding the quote is not predicting it

  • No one predicts these moves reliably. Not banks, not experts on television, not beginners.
  • Knowing why there are two figures says nothing about where either goes. It says only how far behind a trade starts.
  • Money is lost here as readily as made. Keeping a mistake small is the subject of risk basics.
  • Watching costs nothing. A demo account quotes the same live figures against virtual money, and a demo result promises nothing about a funded account.

This site is an independent guide, not a broker: it opens no accounts and holds no money. CFDs are complex instruments and trading them is risky.

Questions about the two figures

Is one of the two numbers the «real» rate and the other a markup?

Neither is more real. Each answers a different question — what it costs to acquire the currency, and what is paid out to part with it — and both are live.

Is there an official exchange rate somewhere that these are based on?

No single institution prints one for trading purposes. There is no central board; what exists is the best offer available in each direction at that second.

Why does the distance between them change during the day?

Because it depends on how much is standing ready to be swapped at that second. At some hours there is a great deal to match an order against, and at others very little.

Two people swap on opposite sides of the world. One market or two?

One. The market is the swapping, not a room around it, and the offers reaching your screen come from all of it at once.

Nothing was swapped for two days and the figure still changed. How?

At the restart. The first offers of the new week carry two days of news, and there was no quoting in between for the price to travel through.

Money changed at a travel counter — is that the same thing?

The same exchanging, with a different ending: the traveller keeps the currency. Two figures were quoted there too, on a board.

Do the trading hours belong to the market or to the broker?

To the market, and to the individual instrument. The hours during which anything is quoted are written into the instrument's specification.

Does a market this size expect a large first trade?

It does not. One lot is the standard size, not a minimum, and 0.01 lot is a hundredth of it.
