What a pain in the arse to even try to train anyone to trade real time, they constantly asking questions while you trying to concentrate, you are missing signals, missing to get out or reverse. They forget most of what you keep telling them hundred times, they don't study enough, they go to parties to "unwind"? They keep telling you what they think I should do and you have a losing trade, they say never would have taken it, but don't say jack when you hit a dozen in a row of no losses. And whatever they can pay, most likely make in less than a day. Unless the poor sap mentor is a masochist and enjoys pain, the student is going to have to watch him a fricking year and sit next to mentor just watching.
Mentor can show direction, and the student should spend time on proving the directions to be wrong or right for them, but you still need to do the screen hours. And it you think you can just start programming without knowing charting well, you have a long losing road to walk, I think it best you manually able to trade then program.
Maybe most or few at some point of their career have a need to teach someone live, unless you have insane amount of patience and only trading few contracts and don't take many signals, could work out.
