Under what circumstances would my money be in danger in IB futures account? Let's say I have $10K in my futures account and $30K in my equities account. IB bankrupts overnight. Does it mean that my $30K is insured and $10K is not. What happens if I move my money on daily basis from futures into equities account? What protection do large traders have ($1mil or more)? I don't understand how could someone (like guys from "market wizards") have so much money in trading accounts and not being insured.
