Understanding a currency exchange as a relative price
Foreign exchange involves two currencies, so a price movement must always be read in relation to another currency.

The BabyPips introductory lesson explains foreign exchange through an ordinary conversion between currencies. An exchange rate is a relative price: it tells you how much of one currency is exchanged for another. A transaction therefore involves buying one currency while giving up the other.
The market includes institutions, businesses and individuals with different purposes. Travel and international commerce are distinct from speculation on future exchange-rate changes. Seeing the same currency name in both settings does not make the underlying product, cost or risk identical.
For research, identify both sides of a quote and the service through which a transaction would occur. A retail conversion, leveraged contract and institutional spot transaction may have different terms. The lesson provides vocabulary for understanding the market; it does not establish that predicting currency changes is easy or that participation is appropriate.
