I can say this with confidence that most successful traders are private. They trade mainly for themselves and if they offer you coaching lessons it won't even make a difference to them as they are already making money.
When one is personally successful in trades, then surely he is a good quality skilled trader. They teach their students in such a way that only rules have to be followed. You will only start to succeed when you follow their rules and master yourself. Following their rules does not mean you will be a good trader but you should follow their rules besides you should always do market analysis, research because the market is not always same. If you can persevere patiently you will begin to succeed very quickly.
