Anyone have any experience with Simplex, Greenmoore, or any other of these prop/arcade firms that scalp options? I've had offers from a couple but I'm a little skeptical. Their pitch is that trading as a customer and getting priority in the book, they are able to lean on the size and take a nickel or scratch 90% of their trades. My scalping experience is in futures where you can't lean on anything. Do any of these guys make any real money? It seems like a tough way to make a living.
