Quote currency
The second currency in a pair, the one in which the base currency is measured.
How to read the number
The result of a trade arises in this currency, which is why profit on a pair and profit in the account currency are not the same thing.
When the metric lies
In a pair without the home currency the result appears in a third one and is converted at its own rate, so the outcome depends on two moves rather than one.
