1. Every time you buy or sell in the market, you can't lose more than one tenth of your capital. That is to say, when the loss reaches 10% (which is the maximum allowable loss), you must leave anyway, because generally speaking, the loss of 10% is enough to show that the operation strategy is wrong, so you should leave decisively at this time.

2. Be sure to set a stop loss. This is a re-emphasis on the previous rule, but the stop loss is not necessarily 10% of the loss, and it can be set appropriately as needed, such as 5%.

3. Don't buy and sell excessively. The so-called never excessive, that is, the right amount of buying and selling here, has two meanings: first, don't invest too much money when the direction is unclear; The second is not to operate too frequently.

Never let the position you hold turn from profit to loss. Simply put, this is to set the take profit position on the basis of profit. The take profit position is set relative to the lowest profit in the account, and the position set is not lower than the cost price of buying. This is a good way to ensure effective profit.

Never go against the market. On the contrary, following the trend is the most common understanding. But in fact, many people say that it is difficult to grasp the trend, how can we follow the trend? In fact, it is impossible to completely measure the market trend forever, and it is possible to be as accurate as possible most of the time. Therefore, many people focus on forecasting the market trend. In fact, it is basically applicable to know some basic trend indicators (such as moving averages). The key to success is not whether the forecast is accurate, but whether to buy and sell in strict accordance with the forecast trend. Many people clearly know that the market trend and their positions are in the opposite direction, but they find a reason (such as losing money) to hold positions, and eventually they become deeply locked. Fundamentally speaking, it is a violation of this law that leads to such a result.
