You can make a fixed investment without choosing the right time to make a fixed investment. However, the fund will make better fixed investment in the downward trend, and the cost of fixed investment in the downward trend will be lower. The lower the cost, the lower the risk that investors bear, and the greater the probability of gaining profits in the future.

Investors are not advised to make fixed investment in the upward trend. In the upward trend, the cost of fixed investment will be higher. The higher the cost, the greater the risk that investors will bear and the greater the probability of future losses. In the process of fixed investment, if the fund rises, the fixed investment can be suspended.
