A friend of mine went into Friday with a 200k margin call. He was heavily long the metals. So midmorning he sends in 200k but the positions are drastically moving against him. The account goes negative before the wire hits and his intraday margin call has gone to about 800k The clearing firm blows him out of all his positions. The 200k wire would have put the account out of negative LV but they still blew him out I guess because of the huge positions he had and intraday margin call. Can they do that? Were they wrong in blowing him out?
