Quotes are streamed directly from the market, showing both bid and ask. Capital.com adds no spread or markup to the price – the only charge is the 0.4% FX markup.
Where the instrument currency differs from your account currency, a conversion takes place and the 0.4% FX markup applies. The rate shown at order placement is an estimate; the final rate is confirmed at execution (buys) or settlement (sells).
Currency movements can affect your realised and unrealised P&L. Execution prices may also differ from the displayed quote due to slippage, which is a function of market conditions outside Capital.com's control.
Example
Buying by amount (fractional)
You hold a EUR account and buy €500 of a US stock priced at $200. Capital.com converts EUR to USD, applies the 0.4% FX markup, and reserves a small buffer (around 3%) for currency movement, resulting in a fractional purchase of approximately 2.45 shares.
After execution, the final exchange rate is confirmed and any unused buffer is returned to your balance.
