Quote from TraderZones:
one day, there will be a catastrophic event - even just a story published something like Pakistan nuked India.
Sort of like the accidentally published (news was 6 years old) story about United airlines declaring bankruptcy.
These seasoned traders who use extreme leverage will become bugs on the windshield. Then, they will not feel so clever.
Some brokers who specialize in $300 day trading margins will become the blood in the street. They will be overwhelmed by the losses of their customers. $300 controlling $60K of emini? Not so clever on judgement day...
Brokers like IB, who don't allow insane margins, stand a lot better chance of coming through in excellent shape. Customers may see a mega-Refco like event, but much worse.
