The interactive lesson walks these ideas one screen at a time and checks your answers as you go. The text below covers the same ground for reading.

A currency pair is two currencies in one price

The first, the euro, is the base currency. The second, the US dollar, is the quote currency. The number is what one unit of the base costs in the quote currency, so EUR/USD at 1.08651 means one euro costs 1.08651 US dollars.

The ask is the price a seller is asking for the base currency, which makes it the price you are quoted when you buy.

The bid is the price a buyer is bidding
