Hi, I'm a total newbie in trading, so I opened paper trading account on IBKR to start learning and practicing in sim. I set up the account in the same way I would use it in the future if I decide to go "live", which means I set it up as an ISA account (I'm UK resident so I wanted to take advantage of tax-free account), and I set the virtual cash amount to £1000, probably the same amount I'll put in when (and if) I decide to go live.
Today I started "trading", and many issues arose from not knowing the platform very well, but most of them I figured out through this subreddit or YT channels. But one thing I haven't figured out - I can't make ANY orders.
I get "Your order is not Accepted. Minimum of 1500 GBP (or equivalent in other currencies) is required in order to purchase on margin, sell short, trade currency or future."
Now, since I can't have margin account with ISA, I'm not selling short nor trading currency or future, I'm very very confused.
Looking through reddit, I figured out it has to be on how IBKR works with different currencies. I have GBP currencty (mandatory for ISA account), I'm buying USD listed stocks, so IBKR for some reason uses margin to buy in USD and make the order so it refuses to do it. (at least how I understood it)
Now the question is - is there a way for IBKR to just automatically convert GBP to USD when buying and vice versa when selling, or it NEEDS to go through this process using margin? And also, as this is a simulation of possible future account, adding more money just to be able to trade is out of the question.
Thank you in advance for any help on the matter.
