If you're on a search results page that has financial filters, you'll see an Any Price box at the top of the page. Click on that box and you'll see the currency being displayed. USD stands for US dollars, which is the default currency at DealStream. Click (or tap) on USD and a popup menu of currencies will appear. Scroll to the currency you want and click on it. The page will refresh and you can now enter your financial criteria in that currency. 

The following categories have financial filters: businesses for sale, real estate, land, financial assets, oil & gas properties, equipment, and mining properties. 

Note: When you change the currency in a filter, it also changes the currency used for listings. For example, if you change the currency to Euros, the price, sales, and profits of every listing is displayed in Euros.
