Quote from Landis82:
It's ALL about the CLEARING FIRM.
They are the "guarantor".
I just had all my money wired out of MF.
If you or I can't meet a loss the exchange makes good our counterparty and then goes to the broker for payment who in turn goes after us the client.
BTW you have NO protection in the event of a big client blow up - all other accounts with a broker can be used to cover the big blowup clients defecit. Theat's right, they use YOUR maney to pay someone elses debt but do not use e'g. Directors assets first. I discovered this not heavily advertised fact throgh having funds withh Refco - I am talking CFTC brokers here.
