Even that is meaningless for someone with 5 or 6mln in the account. IB in the past purchased private insurance from Lloyds of London I think it covered up to 10mln of non trading related losses per client account if I remember correctly. Not so anymore.
Well yeah guess for all the guys with 6 million dollars looking for a "prop" firm, you are right, they are only insured up to 250k, it might be a million now but dont know in the states, i know its a million in canada now, but you can spread money around, and anyone the government is insuring, you can bet its not going tooo happen, it only happens with prop firms.
