Market playing is to get good enough return without the risks to lose your shirts or burn your hard-earning money. So each buying should be dealt with as you start a new project for others and then you get your return for your efforts. Market crowd is your customer, economies is the background you have to work on and each share is your project to satisfy the crowd and market requirements. As any project could fail, your buying could fail too. Failure is not a problem but fail to design your buying for fail-safe would wipe you out. Do you know the term, "Design failure mode effects analysis?" It is a logical design process for any project which is in the strategic level. How many market players really want to know the failure possibility, probability, affordability, and design failure mode effects for their buying shares per day if not per year? You have to identify, quantify, and reduce design risk of your buying, holding, and selling. It has to provide a traceable record for your reasons to buy, hold, and sell, and the consequences of these projects. You have to get your own way to justify the design of your buying, holding, and selling activities. You have to get a means for continuous return improvement. Most of market if they know what they should do would do skillfully. The problem is most of them don't know what is right way for their project: Some said BHP is in downward trend but all of the assertion is about which line they use and they don't have ideas how these lines set in past and how these line up or down in future. They guess the future based on the random movement of the past. Why do you lose your shirts in GFC? Did you use the same thing now and then? Did you behave the same now as then? What's the logic and sense: 35.8, a stop losses line? It is insane to repeat the way you lose for the dream of huge fortune in future. I was very insane before 2004. I was insane again since April 2011. It was the fact even I felt shamed before but now I just want to be wiser and intelligent. I want to be right logically first. Who care about the lines only? The losers! Did you lost a lot before? Warning: you could lose more in future and be wiped out!
