We always display the currency relevant to your selected marketplace within the formula or function. For instance, if you choose ‘CA‘ as your marketplace, the currency will be displayed as CAD. Similarly, for the ‘US’, it will be shown as USD.
In this example, as the marketplace is set to the US, all amount values are in USD

When we set DE as the marketplace, the amounts are displayed in Euros.

As noted before, when you select ‘ALL’ (where applicable), you’ll see the amount values from various marketplaces, each corresponding to its specific currency.
