When buying US stocks, you specify the GBP amount you want to invest instead of the number of whole shares. Freetrade will then use this amount to purchase a fractional share of the stock, matching your investment as closely as possible.
For example, if you choose to invest £100 in a US stock, we’ll place an order for £100 and buy a fractional share equivalent to that amount - so you get exactly the value you want to invest, without leftover cash.
