I recently made an account with IBKR. It is an IB-UK margin account which is supposed to have a 4:1 leverage. Everything it is been approved with my account by the way. I have above 25.000k dollars in my account. They do not give me leverage and I am not even able to short my full initial equity of account. I message them and they send me just an article to read. What I have to do? This is a serious problem I need help.
