You can edit your currency settings by selecting 'Settings' on your RepricerExpress menu.
If you want to reprice multiple marketplaces through the same RepricerExpress account, you may need currency conversion rates set. These rates will translate your min/max prices from your base currency to the local currency of your other marketplaces. For example, Pounds to Dollars.
RepricerExpress will by default automatically update these exchange rates each morning based on the European Central Bank rates. If you want to control these yourself you can change the setting to 'OFF' in which case you can update the rates manually, as you need to. Some sellers may prefer this so they can manipulate rates to be what they need them to be.
