Exchanges are based on the principle of opening first and leveling first. When we trade, we often follow the logic and do not necessarily conform to this principle of advancing first and leveling first. In this way, what is displayed on the software will conflict with the logic. , leading to confusion in thinking. This situation, for multi-strategy, is indeed encountered from time to time. My opinion is: In fact, in addition to studying the transaction itself, there are many, many things that need to be done to do a good job in trading. For example, the operation of a trading team will update the exchange margin and calculate the benchmark price of positions every day; calculate the statistical table of capital changes corresponding to price fluctuations under each position; analyze and summarize the market stages of each variety, and decide which strategies to bundle. A trading time period will be used or deactivated, and then a trading plan will be formulated. The plan will be very detailed, including the normal conditions that each strategy bundle may face and the entry and exit range, positions, sub-positions, etc., and also plan for emergencies. The response to the situation is not only intraday, but also the response to high opening, low opening or violent fluctuations in the opening; after completing the strategic plan, we will check whether there is any conflict with the product element table of the asset management product, and Whether there is any conflict in the asset management system, whether it conflicts with the overall strategy, and whether it conflicts with the risk control system; if there is no conflict, the transaction plan will be put into the risk control environment for calculation, and the worst-case asset value of all strategies bundled on the day will be calculated. Loss, as a psychological bottom line, if there is a problem with the bottom line, go back and adjust the trading plan, and so on; after the trading plan is completed, each orderr must be clear about the formulated trading plan before the market opens to reduce operational errors. . During the transaction process, in addition to the self-recording of the trading software, the transaction flow will be calculated according to its own requirements, which must be completed by the staff; at the same time, there will be different divisions of labor to complete the market tracking work during the opening period, risk control work, etc.
