If a Multicurrency Solution is enabled in your account, any transactions that involved a currency exchange can now be found by navigating to Intelligence -> Currency Exchange.

Select the main currency of the account. This is the currency that will be used to process all payments in the account when interacting with third party payment providers.

This configuration set in Admin -> Account will stablish the name to be displayed for the account, which currency or currencies the account will accept, if taxes should be included in price or not, languages, country, among other general settings related to the account.
