>The exchanges are only required to make order information public with a significant delay. However, they sell the real-time order information to a few market players enabling them to engage in the dubious tactics at the expense of other players. It's easy to see why you view this as unfair. But it is fair. Anyone can buy the real-time information if they have the capital. Obviously markets are going to be more friendly towards you the more money you throw at them. Just like everything else in capitalism, the fairness comes from anyone being able to have money. If you think this is unfair, you're essentially opposing capitalism.
