Interactive Brokers will automatically convert currencies when trading non-GBP denominated securities. To do this, Interactive Brokers will engage in “spot” currency transactions on your behalf in order to settle your buy orders or convert the proceeds of a sell order. For opening orders Interactive Brokers will base the exchange rate off the spot exchange rate at the time of trade plus our 0.03% fee. For closing orders any non GBP balances will be closed at the end of the trading day at the closing exchange rate of the day plus our 0.03% fee.
The below example illustrates the cost in GBP of a $1,000 USD Trade
Example GBP/USD Spot Rate: 1.3432/1.3433
| Order Type | FX Conversion Rate inc 0.03% fee | Cost of $1000 USD Trade |
| Buy | 1.3430 | £744.61 |
| Sell | 1.3435 | £744.31 |
