If a trader buys or leases a exchange seat, they are basically their own broker, no? How can I trade CME without a broker, and how much money will this cost? I'm sorry this is a basic question, I have no background in institutional companies.
I should have noticed that the largest firms in the nation use brokers. Some smaller in person "friends" I know were saying they were their own brokers. I wish I didn't assume they were truthful.
