All trades at BUX will be done in your base account currency

So if you have an account in the United Kingdom, your base currency will be the GBP (£). 

This means that if you trade £100 in Facebook stocks, for which the price is in USD ($), we use the same exchange rate for the entire period that you keep this position. If the exchange rate of the USD ($) against the GBP (£) changes, then this doesn't have an impact on the result of your investment. This way, you'll never run into any surprises.
