But it's program rules are unclear. Some of the programs require licenses. And they do not specify if there is a per share commission depending on the program. I know litespeed has pretty competitive commission but I don't know about these guys.
The underlying of the futures contract can be the stock indexes or corn or crude oil, or bonds or a whole host of others.
it could also be stock then. how do they expect to compete charging 4 dollars per stock trade? did you make that up?
Topstep doesn't allow stock trading; it is futures only. It is just a bit under 4 dollars per contract round trip which as stated before is pretty standard for futures trading.
It's just under $4 per round-trip. It's not stock trading. It's futures. If you can find a way to trade futures for much less than that, good luck to you. For myself, I strongly suspect you have no idea what you're talking about.
