It is obvious that trading has concepts. There are even rules and factors to consider in trading. There is also knowledge and discipline to take when engaging in trading. This alone can obviously tell us the concept about trading.
Trading isn't like gambling where you guess and put your bet and you are ok waiting to either win or lose. Trading needs learning, a grasp of different concepts in order to maximize profit. There is also these tecnical and fundamental analysis that has lots of concepts to offer.
Trading is not only the attitude and traits to follow but also follows learnings and adaptability of the decision a person should do in case of a different situations in hand.
The concepts and everything that has to do with the theory in trading is already a matter of seeing what they want to become familiar with, be it one theory or the other, as far as I am concerned it is that I have always used Wyckoff's theory, something of Livermore's teachings and also with other theories, but I have something to lean on, however concepts as such do not exist for me, everyone interprets trading according to what they learn, what they read or what they learn in certain academies or what they that they learn as their own method, but concept, the word concept is something general and I think that instead of concept what exists are specifications.
