Basic Forex Terminology
Base Currency and Quote Currency
Base Currency: The first currency listed in a currency pair. It represents how much of the quote currency is needed to buy one unit of the base currency.
Quote Currency: The second currency in the pair, which shows the value of one unit of the base currency.
Example: In EUR/USD, Euro is the base currency, and USD is the quote currency.
Pip
A pip (percentage in point) is the smallest price movement in a currency pair. For most currency pairs, a pip is the fourth decimal place (0.0001). For pairs involving the Japanese Yen, a pip is the second decimal place (0.01).
Lot Size
A standard lot in Forex trading equals 100,000 units of the base currency. Other common lot sizes include:
- Mini lot: 10,000 units
- Micro lot: 1,000 units
