When Octoboard connects to a cloud application it retrieves data in the currency that you use in that application. For example, if your Facebook Ads account is setup in British Pound (GBP), we will get all Spend, Cost Per Click and other metrics in British Pounds.
Since we do not know what currency is being used (we can not ask this information from Facebook), by default, we will display a dollar sign ($) next to financial metrics. However, you can always override this default value by specifying another currency in Octoboard.
To change currency symbol, go to LEFT MENU, select CLIENTS, choose your CLIENT, select "Formatting" tab and use available configurations as shown on this image:
Please note that this configuration is defined on a PER-CLIENT level. This means that if you have multiple clients operating in different currencies, you can always set different currency symbols for each individual client.
It is also possible to change currency per widget. Click top-left corner of your widget, select PARAMETERS and use Options tab to manage currencies.
