Remember when Nasdaq had mmid's so you knew when GS was buying or selling? Is there anybody here old enough that profited from this strategy? The reason I ask is because Bovespa trading occurs exactly like that. GS shows their hand so does Credit Suisse and everybody else. How do we profit from a new market like bovespa which is full of inefficiencies?
You hack into the local power grid and cause power outages to the BOVESPA Exchange and then bid-up and offer-down EWZ elsewhere.
