I plant my flag somewhere in the middle of all of this. Yes, it's possible to develop an intuitive sense of the market IF one is immersed in the action and his cash outlasts his learning curve. Most, however, don't take this route. They trade part-time or they trade swings or they trade whatever other incidental opportunities present themselves. They therefore take far longer to learn the pulses and the rhythms and the flows, if they ever do, and it is during this stage that "psychological issues" are most likely to present themselves.
I used to think that one needed to "get in touch with himself" and examine his feelings and his fears and his hopes blah blah, but I eventually found that if one had a consistently profitable trading plan, the "psychological issues" pretty much evaporated. After all, it is no great leap to imagine that the less confidence one has in what he is doing, the more likely he is to be, for example, fearful (of pulling the trigger, of taking a loss, of cutting profits short blah blah).
Few things breed confidence and discipline as well as a consistently profitable trading plan. And if one is confident and disciplined, what is there to get all emotional about?
Of course, one must also decide just what it is that he wants from the market, and few people go beyond "make money", but so few do that one wonders just what it is that they really want from the market. So my first questions have to do with what the trader-to-be wants. Then he figures out how to get it. And with at least two charting programs offering replay functions, what used to take a year can take less than a month.
The stick in the spokes, of course, is developing the plan, which most people will avoid at all costs. But it's a lot easier and a lot cheaper than therapy, and probably more effective.
