sustainable profitable growth The knowledge of the futures market is not too much. If you work hard, you will be able to learn the knowledge of futures by the end of the year. So the introduction of futures is very easy, but this is only the first phase of learning. After completing this initial study, many people conclude that futures are easy to operate and start trading. As a result, losses ensued, and in real deals he found that he had too much to learn. This will allow investors to move quickly into the second phase of learning: confusion and confusion. At this stage, investors find that there is so much to learn that they don't know what to learn. It seems that everything needs to be learned, and it seems that learning nothing is useless. Most investors are not able to get through this stage and are eliminated from the market. Investors who can get through this stage will enter another state where he can form his own trading philosophy, form his own trading patterns, and even form his own trading philosophy. In other words, his mind and trade have formed a system. But he still phases into the state of investors profit, it is impossible to a steady profit, the average person after reaching this state, he again learning motivation will gradually lose, he started to cycle around their own system, he felt he had to understand the market: the market. But the market is far from "just that". His own system began to become a barrier to his further learning, and he began to close himself, deny others, even laugh at investors in the first two stages, and refuse to communicate with others. Indeed, there are not many people who can reach this stage, so he becomes lonely and it is difficult to learn and progress again. When investors reach this stage, they will form their own system: technical or fundamental, or policy-based, much like the wuling faction, each other light. However, the study of the futures market is really starting from the third stage, which is equivalent to the basic course, and the third stage begins to enter the specialized courses. The first two stages are all knowledge, and the third stage is to learn skills. The learning of skills is endless and the continuous improvement of skills is the foundation for you to stay profitable. The conversion of commodity value into cost price + profit (k+p) includes the possibility of deviation from the residual value. Because profits for more than the balance of cost price, and the cost price is less than the goods value, it provides the individual capitalists in cost price above and below the value of the possibility of selling goods, so that to achieve the profit with the goods actually contains surplus value does not agree in number. The capitalist makes use of the difference between the value of the commodity and the cost price, as a driving force in the market competition. As the competition between different production department and the free flow of capital, make different special margin balance into average profit margins or average profit margins, so that the profits further into average profit, realize the amount of capital to achieve the same amount of profit. In the usual case, the average profit and the surplus value are inconsistent in quantity. The average profit is proportionately proportional to the total amount of capital in advance and not the amount of live labor that is governed by individual capital. This and make an objective truth, essentially profits is the product of capital, it is nothing to do with labor, in this way, capital on the relationship between the wage labor to make money and to be make, will be further. In the near future, the car owner who has changed the gasoline pump or unloaded the gas pump will not panic if there is a gasoline smell in the car. It is likely that the residue has not been cleaned up after the removal of the vehicle. The probability of such a situation is small, and the general replacement cycle of the gasoline pump is 100 thousand kilometers. But the gasoline filter is connected with the gasoline pump. The replacement cycle is shorter and the gasoline pump needs to be removed when replacing. In this case, simply check the installation of the gasoline pump and clean the surrounding area. In New York, the U.S. energy information administration (EIA) released data showing U.S. crude inventories fell by 649.5 million barrels a day in the week ended Dec. 15, beating expectations. Gasoline stocks rose by 12.37 million barrels, but the increase was less than expected. Although an enterprise's internal trade fair eliminates or reduces some of the market transaction costs, it also brings with it the specific transaction costs of the enterprise. The main reason for this defect is also the incompleteness of information. Specifically, first, there are various contractual relationships among enterprises, including contractual relationship between enterprises and workers, contractual relationship between enterprises and managers, etc. The enterprise should supervise the work of the workers and products that it employs, as well as the managers and other personnel, and induces them to work hard for the enterprise. So, companies are signing contracts and spending on oversight and incentives. Secondly, on the one hand, corporate decision makers often need to obtain information from subordinates. On the other hand, the decision-making information of the upper level of the enterprise should be realized by passing it to the subordinate. The information transmission of these two different directions will be distorted by the increase of subordination of enterprise scale, resulting in the loss of enterprise efficiency. Once again, the subordinate of the enterprise often conceals or passes the wrong information to the superior for selfish motives, so that the superior can make decisions that benefit the subordinate. Or, the subordinate's decision to the superior only passes or executes the part that is advantageous to oneself. These will result in the loss of enterprise efficiency. Thus, the expansion of enterprises is limited. According to coase's theory, the scale of the enterprise should be expanded to this point, that is at this point to increase the cost of an internal exchange cost equals the cost through the market exchange cost and so on.
