If all your ad accounts for a given network share the same currency, that currency symbol appears next to the cost figure in the Totals Bar and throughout the table.

If you have accounts in **multiple currencies**, TheOptimizer does not perform automatic currency conversion. Instead:

* The Totals Bar adds the raw values together regardless of currency
* An asterisk (`*`) replaces the currency symbol
* Hovering over the asterisk shows a tooltip confirming that multiple currencies are present

<Warning>
  When accounts in multiple currencies are selected, treat the Totals Bar as a directional indicator — not an exact financial figure. For precise reporting, use the **Ad Accounts** filter to narrow down to accounts that share a single currency before reading the totals.
</Warning>

***

## Filtering by Currency Tag

Every ad account is automatically tagged with its currency when connected. You can use this tag in the **Ad Accounts** filter to instantly scope the view to a single currency — for example, selecting only `USD` accounts before running a report.

To add or customise account tags, go to **Integrations → Ad Network → Ad Accounts**.
