#### **Description**

##### *Financial meaning*

**FX Rate**, or exchange rate, is the price of one currency (base currency) in terms of another currency (quote currency).

##### *Platform abstraction*

**FX Rate** in Finmars (a.k.a. Currency history) is an entity which evaluates a [currency](https://docs.finmars.com/books/entities/chapter/currency "Currency") (base currency) in system default currency (quote currency, USD by default) on a specific date for specific [pricing policy](https://docs.finmars.com/books/entities/chapter/pricing-policy "Pricing Policy"). By default, system currency is set to USD, it can be changed in [default settings](https://docs.finmars.com/books/default-settings "Default Settings"), but it's not recommended due to some modules may depend on system default currency set as USD.
