What are they? Where you can see all the offers, not just the highest bid and lowest ask? Can I get them at interactivebrokers? And can one trade profitably using the simple system of watching them, and when a ton of orders pop up on sell side or buy side, act as if that was going to be downward/upward pressure, and sell/buy accordingly? I'm sure its not that simple, just curious how they might be used.
Thanks!
