Just a tip which might be helpful for you.....you can gauge the reputation of any trader by viewing the number of times he has been thanked for his posts. However this is just one broad yardstick and by no means a general rule.
I feel All the senior traders are successful in their own way....its not correct to rank them by picking few of the lot as THE BEST.....each has their own style and knowledge. You can follow the one whose trading style/psychology matches with yours.
