I have been looking to open an account at one of the better capitalized, large FCMs (Goldman, JP Morgan, Morgan Stanley, etc.), and it seems like they do not take individual accounts. They all seem to be looking for corporate accounts, CTAs, funds, etc. Is there any way to open a futures account at one of those big firms? Account size requirement, annual commission threshold, etc. The reason I am looking for a big FCM is that it seems the smaller FCMs don't have access to swaps, and cash fixed income, which is a big fly in the ointment.
