Hi, I have an account with IB that I don't use anymore, its a Reg T account, and decided to withdraw funds last week (GBP). Bringing the balance close to zero. I have no open positions at all, yet I get a margin call on friday telling me they have liquidated my positions and sold Â£4950 GBP. My account is now -Â£4950. Can anyone tell me why this has happened and what I can do about it? Is this a mistake considering I have no positions open? Thanks in Advance.
