Quote from powerfade:
Care to explain that for the ill-informed among us? You mean our orders never go to the exchange? Or you mean that they take the other side of our trades legitimately simply because they know that the majority lose? If so, what do they do when they find a trader who's making the right calls? Code his account so that they aren't taking the other side of his trades?
EDIT: If you mean that they're taking the other side of our trades at the same price that we would have got had they routed to the exchange, simply because they know that the majority lose, then who cares? Why would anyone care? As long as they're not manipulating data, does it matter who takes the other side of your trades?
