and the trading model used by ltcm probably makes th's look like a 6th grade project. what's your point?
No one will ever have a 100% garantee. Your money will always be safe until it is not safe anymore. But by the time you will know that it isn't safe anymore it will be too late. That logical no? That's the way it goes everywhere, banks brokers, big companies, small companies, a friend you lend money to...... Conclusion: never put all your eggs in one basket. Trade through several brokers. The possibility that they will all go broke is minimal.
