Does anyone know the answer to this?

Hello long term index trader (on other platforms) new to FX. My base currency is SEK but I have so far only played around with EURUSD in a demo account trying to learn the FX profession. How is the exchange rate determined from SEK to EUR when I enter a trade? Is it per tick intraday? Does this mean a gamble on EURUSD is as much a gamble on SEKEUR? Is this exhange taken into account in the demo account or will the fee for exchanging SEK to EUR be a nasty surprise once I go live? Or am I overthinking this?

How do I get rid of these order tickets that are flickering with the price but never got executed? I cant click on the x since the whole order bar is grayed out. Very frustrating.
