I plan to have lot of trading activity.Yes, you absolutely can and IBKR has great exchange rates, so some people use IBKR to transfer funds from one country to another while also converting to another currency.
But IBKR does not like this - you should always also have trading activity.
I was planning to fund IBKR account from UAE bank account after moving to UAE to start trading.
I was just worried about withdrawal of profits to UAE bank account. Now it looks like I can use bank account from any country to send and receive funds to/from IBKR after moving to UAE.
Thanks for the clarification.
