Some are trouble maker like this Melissa Pinto of IBKR Mumbai, Maharashtra, India. Her title Team Lead - Dispute Resolution (from linkedin). I had one of clients arguing with her and the result is she closed his account almost immediately. So now I am trying to manage his $300k from another platform. I managed a total of 15 accounts in IBKR and different accounts get different settings some requests like European index options got totally rejected. What ever regulations they quote do not come in harmony for different accounts.
