Torque is the force that causes the object to rotate. Engine torque refers to the moment when the engine outputs from the crankshaft. It is inversely proportional to the engine speed under the condition of fixed power, and the faster the torque is smaller, the larger it is, which reflects the load capacity of the car in a certain range. 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.

So, again, stay objective and open, don't close yourself, always be curious and curious, so that you can get motivated to keep moving forward. Strictly speaking, closing yourself out, denying someone else is the equivalent of your trading life going into the end. The key is to see what you want. Identifying your pursuit determines the direction and motivation of your study. The market is changing, the pursuit is improving, so you never stop learning. Through continuous thinking and learning again, I found any trading tools on the market and reasonable analysis method has its existence value, but there is a reasonable value, not the existence of absolute value. The market will always operate under these limited factors, but different stages affect the dominant factors of the market. If you close yourself and stick to some idea, then when the market's dominant factor is not your acceptance and understanding, you will be in a state of confusion and loss. Not learning or accepting other valuable things is equivalent to losing a lot of market opportunities and understanding the market. The market is very big, the connotation won't have big change, but the disposition and the expression way but often change. If you don't keep learning and absorbing, you will eventually be eliminated by the market, regardless of who you are.
