t is more difficult to improve ability than to master knowledge. Profitability is dependent on ability, not knowledge, so you should understand why I say the ability to learn is the equivalent of trading profit. Ability can be divided into: the ability of market analysis, understanding of market performance ability, ability to sense the state of the market, the impact factors of market leading identification ability, reading ability in the subject matter of the charts, operation planning skills, and ability to execute.

In another extreme cases, all the production in the economy in a large enterprise, such as the complete car was produced in the enterprise interior, don't need to make any intermediate products trading market. Therefore, the same transaction can be conducted either through the organizational form of the market or through the organizational form of the enterprise. Companies exist, or companies and markets coexist, because some transactions cost less in the enterprise, while others cost less in the market.
