fluttrader is apparently the only one around who has any experience with him, that's why you aren't getting any other info ... nobody else has "been there, done that". Like I said, give it a twirl and if you like it ... buy it.
I don't think seeing his statements is adequate. Let's assume he produces them and you can confirm what he posts in the chat room in realtime. All that tells you is he very good, but it doesn't mean you will be anywhere near as good. Also, be aware his room is NOT a trade calling service--he posts after he is already filled and so you will not be able to copycat him unless the price drops below his entry and at that time, he maybe looking to exit. You are on the right track. Wait for replies from actual students who purchased the course(s). The key question is: are they consistently profitable using the methods. Try to speak with them to test their sincerity. Alternatively, ask him if he will refer a few people to you if you come up with goose eggs here.
Does anyone know why no responses from previous customers are being received to the question? Can any conclusions be drawn from that?
