2. statistical analysis of trading results
3. statistical analysis of various trading systems in order to rank them by effectiveness and risk adjusted return

6. at institutional level, the relationship between now and supply and demand in determining price
7. the ability to forecast market responses based on the law of large numbers and mass psychology

8. tolerance of uncertainty, ambiguity and risk
9. articulation and operationalization of goals and objectives into quantifiable measures
10. qualitative descriptions of successful outcomes of your trading practice
