In this article I will share with small add-on I developed for one of my customers.
Let’s assume that you are employee of company that uses CRM with several currencies. Of course you want to have actual information in your system and currency exchange rates should be current.

Every currency has exchange rate field that is used for calculation of base fields of your currency fields but there is no out-of-box possibility to actualize exchange rates.
