I have a Roth IRA account with IB and my base currency is Usd. I would like to trade the FDAX intraday. My understanding is that with this account type I would have to execute a currency trade on IDEAL because you can not borrow currencies with a Roth IRA. So my question is: If I purchase enough Eur.Usd to cover my trading on FDAX, should I just hold the Eur.Usd position or close it out on a daily basis? And if I should hold the Eur.Usd position should I hold it for the week or just hold it as long as I continue to trade the FDAX?
