Traders` mistakes

Here is my point of view about mistakes of trading, in which many people are involve. So, first of all I want to admit something that Glen Neal has written in his time. Every market needs a serious analysis of a situation to appreciate a stage where it is located.( it`s not word for word, but the thought is right). It sounds like an easy thing, but it`s hard to do that(!) firstly, because of the appearing of a question: what are the determinant factors? So, the first thing I`m thinking about is that we have to fight with a light-mindedness in trading, and the second one is - removing from use a "fictitious" methods of analysis. The "fictitious" means when we are getting data from some esoteric indicators, or from the indicators which are analysing some relative power, occasional methods etc. The method of intuitive analysis which I've described earlier, also from esoteric sphere, but I would not compare it to the things which are far from reality. There are also some other points.
Let me stop on these ( let`s not take an intuition into account, because it`s not a fatal mistake). The light-mindedness. A typical script: we are trying to find the levels of entrance in the market, for ourselves. Entering. Then the market is starting to move against us, and we are shutting down even before the losses. The first foolish thing that we are making when we are trying to resist subconsciously, is to stop losses with about 30 -50 points. It`s too much. The ten points and lower - it should be enough ( for such kind of futures as on euro). The second one is: suddenly we are realizing: that all of these levels (our fictitious calculations) - ARE NOT RIGHT. Everything that we have designed is a useless scrap of paper. Which are not confirmed with anything of current market situation, only with smart books. It`s perfect, you can also show your friends impressive pictures, but all of these things are simply imagined.
Isn't it? Were all these levels given to you from exchangers? Yes, there are some examples from the history, and also many profits on the history papers. The moving and the Fibonacci`s network. One of our analytics also have started his way as technical analytic/market trader and then in his books he wrote about necessity of learning economical events, which are happening. I also was impressed by the guys who are working with the data transmitted directly from the exchangers: quotations and the range of the auction. It makes sense. Because of analysing only those levels where was the speculators activity.
