i've used both and carlin trader goes down less. they have the open book and a demo. u have the option to hold orders at the server, but i never used that option. i was paying .0075 and no other fees.
trust me im not defending them nor am I too smart to avoid their little games. I get screwed by those pigs daily. but it is just part of the game. but that is sometimes how i make money by taking advantage of the ineffeciency of the NYSE.
we all use the specialist system to profit from NYSE trades. It is definately an unfair system but it gives us and edge if we can get on the right side. what is wrong with just enforcing the specialist rules better?
i've read it and it is definately good but it wasn't what i expected. no concrete examples of tapereading. i don't know if im just reading the wrong books but everyone seems to just be telling their own personal story.
