Honestly I would say having John in your back pocket, so to speak, is extremely valuable. If you don't understand something, even the smallest point, you just pop him an email or call him.
For a few months on 5 markets I practiced creating levels. 3 of those John did levels too and each day I compared mine against his. It can take a bit of time to clearly see on the chart as you train yourself. So I would email him questions a few times a week. Without this communicate the course would not of had its main benefit.
I have great contempt for those private sellers selling John's course....lol..... Failed traders one and all. You sign a contract before the course is delivered. In this world what comes around goes around there is ABSOLUTELY zero way around this fact. I understand most have no clue that this last statement is true.
