The Exchange Bot helps you keep multiple Books in different currencies in sync.
It works by mirroring transactios from one book to other books, automatically applying updated conversions rates.
For every transaction in a base book, it will generate another transaction on associated books, with different currencies.
The Bot also adds a menu item to your books too update gains and losses, based on exchange rates variation.
The Exchange Bot uses rates from exchangeratesapi.io by default, but any rates source endpoint can be used.
