If anyone has this same question and need this information in the future - refer to the below.
The question basically being, ‘what is the usd rate you apply and where can you find it’ I have provided the message that support sent me below.
Greetings,
Thank you for contacting us, we hope this email finds you well!
When you are placing a trade with a stock which is traded in a different currency than yours, we convert your money to the respective currency by using the current exchange rates which we display on our CFD platform, which you can access by having a CFD account.
In case you would like to see the exchange rates which we apply, I would advise you to create a Practice CFD account.
Should you have any further questions, please do not hesitate to contact us.
Kind regards,
Teodor G.
