The theory that a trader must have to be successful is almost known to all traders but not all are able to carry it out well, about discipline sometimes traders will break it even a soldier who is used to discipline will also find it difficult to remain disciplined when becoming a trader.
Intellectual or skill about trading is what traders sometimes do not have so they trade like gambling just following feelings and eventually lose everything.
To become a quality trader we must continue to evaluate what trades made us lose that day and vice versa.
Every trader may be able to understand the theory because it is only limited to learning that we can read or learn, but what is more complicated is when trading directly. Because there will be a difference between theory and practice and we must be able to adjust to the situation we are facing. In theory, we may talk about mentality, for example, what we should be like and how. However, when we are directly in trading, the mentality is very different because we feel it directly. We can no longer speculate for a long time, because we have to be quick in making decisions. Sometimes when we theorize we say we are ready with that mentality, but when we trade directly, it turns out that it is not as easy as we imagined.
