I don't want to just shill for Lightspeed here. There are other brokers who offer some of what IB offers at lower prices. You honestly would be shocked at what rates are available with no volume requirements whatsoever. I'm talking about regular SIPC firms and not prop. Some prop firms offer a range of markets similar to IB and at lower rates. The one advantage of IB has always been its breadth of offerings but there are similar firms. It pays to look around folks.
