since futures accounts aren't insured like securities accounts are with SIPC, anyone have experience with how market crashes affect the liquidity cushion of futures brokers? I'm with Tradestation, who clears through RJ Obrien. Obviously RJ Obrien made it through the 2000 crash. Anyone remember if the 2000 crash caused futures firms to go out of business? If so, what happened to customer accounts? The reason I ask is say some idiot leverages up and gets wiped out, and a broker is stupid enough to let it affect its net liquidity.
