You know I have exactly the same idea about this issue. If you are a Broker, chances are it will make easier for you to find him. Just tracking secretly your clients activities.
Fortunately, you can try with me. You give me some money to start then you secretly monitor my trades and do exactly the opposite of mine. Does it sound good? When can we start?

Quote from romik:
Has anyone tried trading against a total loser by opening reverse trades? Losers are not easy to find on BBs, more chances in the open world, that is not an issue anyway. The difficulty comes from finding The One that consistently makes wrong trades and going against him.
