"So it is not by chance that there are so many people trying to add complexity to the markets. Whatever rules are put in place, whatever metrics are devised, traders will try to find ways around them. In an engineering system, if you find a poorly designed valve in a nuclear power plant and replace it with a new and better deigned one, the new valve doesn’t try to figure out ways to make you think it is closed when it is really open. But traders will do that."
