EUR/USD: the Euro against the US Dollar
EUR/USD is the price of the Euro measured in US Dollars, and it is the most heavily traded currency pair in the world. The Euro is the "base" currency and the US Dollar is the "quote" currency, so the price tells you how many dollars one euro is worth. Because it links two of the largest economies on the planet, it tends to be steady and deeply liquid, which is why many beginners start here.
What EUR/USD is
EUR/USD pairs the Euro, the currency of the Eurozone, against the US Dollar, the currency of the United States. The first currency listed is the base and the second is the quote. If EUR/USD is trading at 1.1000, that means one euro buys 1.10 US dollars. When the price rises, the euro is getting stronger against the dollar. When it falls, the dollar is getting stronger against the euro.
Movement is measured in pips. A pip is the fourth decimal place for this pair, so a move from 1.1000 to 1.1001 is one pip. EUR/USD is the single most traded pair in the world, and it carries the nickname "Fiber". You do not need to know the nickname to trade it, but you will hear it used.
What moves it
This pair is a tug of war between two central banks. On the euro side sits the European Central Bank (ECB), which sets interest rates for the Eurozone. On the dollar side sits the US Federal Reserve, often called the Fed. When one of them raises or cuts rates, or even hints at it, the pair can move sharply.
The key idea is the interest-rate differential, meaning the gap between the two central banks' rates. Money tends to flow toward the currency offering the higher relative return. So if the Fed is raising rates while the ECB holds, the dollar often strengthens and EUR/USD can fall, and the reverse can lift it. Beyond rates, watch inflation data, growth figures, and jobs reports from both regions. The US Dollar is also a "safe haven", which means that in times of global fear investors often buy dollars for safety. That can push EUR/USD down even when nothing has changed in Europe.
When it is most active
The forex day moves through four main sessions, all given here in UTC: Sydney roughly 22:00 to 07:00, Tokyo roughly 00:00 to 09:00, London roughly 08:00 to 17:00, and New York roughly 13:00 to 22:00. These are standard-time hours and shift by about an hour when regions move on or off daylight saving.
EUR/USD comes alive during the London session, and especially during the London and New York overlap, roughly 13:00 to 17:00 UTC. Both the euro's home market and the dollar's home market are open at once, so trading volume and price movement are usually at their highest. The quietest stretch is the late Sydney and Tokyo hours before London opens, when this pair often drifts. If you want activity, the European and US hours are where it lives.
What to know as a beginner
EUR/USD is the most liquid pair in forex, which simply means there are always plenty of buyers and sellers. High liquidity usually brings tight spreads. The spread is the small gap between the buy price and the sell price, and it is a cost to you on every trade. Relative to almost any other pair, EUR/USD's spread tends to be among the lowest, which is one reason it is friendly to learn on.
It also tends to move in a relatively orderly way rather than in wild, thin jumps, though it can still react fast to central bank news. Trading is risky and most retail traders lose money, so treat this pair as somewhere to practise sound risk habits, not a shortcut. Those habits, like position sizing and discipline, carry over to other markets too, but at TradeInTune the teaching is forex first.
Common questions
Why is EUR/USD called the "Fiber"?
"Fiber" is just a long-standing market nickname for EUR/USD, the way GBP/USD is called "Cable". It does not change anything about how the pair works. You can trade EUR/USD perfectly well without ever using the nickname.
Is EUR/USD a good pair for a complete beginner?
It is a common starting point because it is the most liquid pair and usually has one of the tightest spreads, so your trading costs are typically low. It also tends to move in an orderly way. That said, it is still risky and most retail traders lose money, so start small and focus on learning.
What is a pip in EUR/USD?
A pip is the standard unit of price movement, and for EUR/USD it is the fourth decimal place. A move from 1.1000 to 1.1001 is one pip. Most platforms also show a fifth decimal, called a fractional pip or pipette, for finer pricing.
When is the best time to trade EUR/USD?
Activity is highest during the London session and the London and New York overlap, roughly 13:00 to 17:00 UTC, when both major regions are open at once. The hours before London opens are usually the quietest for this pair.
