I use interactive brokers.

The cost of a ES mini (SP500 mini future) trade is $2.40.

Stocks trade for half a penny to a penny per share with a minimum of $1.00 per transaction.

I think they require 20k to start a new account these days though.

IB has been by far my favorite brokerage

For those who use IB: How long have you been using them? Do you use their client or their API? Is it alright to use both, in parallel? People complain about their customer service; have you had any problems? Is it easy to transfer money to/from your IB account?
