Quote from 2rosy:
aren't all equities routed away or traded on a dark pool now. I thought anything going to an exchange is what no one else wants.
I do see that lime offers futures and options which is new.
All trades are routed directly to an exchange, this beats IB checking your order first with Timberhill. Also, IB does not allow a trader to route away from an exchange, where as Lime does.
