1. The initiative principle uses its own "initiative" to enter and exit, control the risk (profit and loss) of futures trading under its own eyes, and realize the futures profit and loss by itself. 2. Micro-differentiation principle "Micro-differentiation" The time for profit, loss and position (especially loss) is controlled within a few dollars of the price difference. Stick to the post for the longest time, just a few minutes; The shortest, only 2 or 3 seconds. Decisively enter and exit, and never delay holding loss orders for any reason for a long time. 3. Independence In principle, the profit and loss of one transaction has nothing to do with the next transaction, and the decisive entry and exit of the next transaction cannot be affected by the profit and loss of the previous transaction or the entry and exit price. 4. The principle of objectivity is short selling in the day. The most intolerable thing is that the market of the day was decided subjectively in advance. Short-term speculators subjectively think that they can only go long or short today, which is a wrong thinking. 5. Break-even Principle "Break-even" means that short-term speculators earn and lose roughly the same amount in each transaction. The reason why speculators can make money is to win by "probability". Assuming that there are as many gains as losses every time, there are 100 transactions on that day, of which 70 are gains and 30 are losses, then the day is earned. Speculators only calculate the profit and loss of the general ledger every day. Of course, you'd better control the loss of each transaction within the profit of the previous transaction. In other words, if you earned 20 yuan in your last transaction, the biggest loss of your transaction can only be 20 yuan, so you should stop the loss in advance before the loss reaches 20 yuan.
