After the fund is bought, it can set a profit point and sell it when it reaches the profit point. However, the time to reach the take-profit point is not fixed. For example, it reaches the take profit point in 6 months and sells it in 6 months; 1 year reaches the take profit point, and then holds 1 year before selling. The selling time is related to the set profit-taking point. It is suggested not to set it too low or too high, so as not to cause the fund not to be sold or affect the income.
