Take profit skills: when the fund reaches the expected return of investors and starts to take profit, it is uncertain whether the fund will rise in the future. You can take half of the profit to ensure part of the income, and the fund will continue to rise and then take half of the profit until the fund is sold. When the fund falls after reaching the expected return, then investors can completely take profit.

Stop loss technique: Stop loss when the fund losses reach a certain proportion. Stop loss is to control risk. Investors can sell all the funds for replacement, or add positions to reduce costs. After the cost is reduced, the risk is reduced and the probability of returning to the original is greater.
