In forex trading, EURUSD is the abbreviation for the currency pair of the Euro and the United States Dollar. The Euro is on the left side and is the base currency while the US dollar is on the right and is known as the quote or counter currency. When you see a price quoted for EURUSD, it means that one euro is worth 1.17 dollars. In other words, you would need to spend 1.17 dollars to buy one euro.
The reason why EURUSD is such a popular currency pair to trade is because it experiences low volatility relative to other pairs and has very tight spreads. This makes it an ideal choice for traders who are looking to take advantage of small price movements in a short period of time.
