Brokerage fee is a fee they use to take your money. :-))

Mine has 4 different categories for a total of $4.72 per round turn. As long as it stays there, or goes down, I don't concern myself with how they divvy up the money.

Maybe one of the brokers can better answer your question. I just thought I would smart ass off cause as slow as this place has become it might be two or three months before anyone replied.
