When you instruct us to trade U.S. company stocks, the order's basis is the value of the shares you want to buy or sell (unless you're closing your investment, in which case we'll sell all your owned shares) in British Pounds Sterling (GBP).
For a buy order, we'll then handle the currency conversion with our FX partner, Airwallex.
They convert your GBP into U.S. Dollars (US$) before our investment broker acquires as many shares as possible in your selected company, based on the current market price.
For a sell order, our investment broker will sell the company shares you own at the best available market price.
Following this, Airwallex will convert your money back from U.S. Dollars (US$) into British Pounds Sterling (GBP).
