Hi, Here is the situation. I recieved email from broker compliance dept. to explain minor infraction. Problem was related to small amount of money and shares and was related to my very small unintentional error (one of my accounts bought very small number of shares the same time as other account sold). And I was told to explain why this happened within 5 business days. Few hours later after original email my account was frozen - no buying, no withdrawals. Compliance Dept. kept total silence and emailed that they would take as much time as needed for investigation. Luckily they lifted freeze 1 day later , but they don't want me as a customer any more. They refuse to give reason - just ignore my questions. My main question - is it possible to find out reason? Can anybody guess the reason. Also, I am curious - can brokerage refuse customer without reason pointing to their stated policy? I somehow suspect that they paid more to exchanges for some of my orders than commission they charged. Any ideas?
