Funds can take profits when they are profitable and consider adding positions when they are losing money. Investors can set take profit and increase positions (positions are decided by investors themselves, and each investor's situation is different). When the fund's profit reaches the take profit point, it can take profit, or when the fund's loss reaches the add position point, it can add positions.

Fund take profit: it is uncertain whether the fund will rise in the future. You can stop the profit by half first and guarantee some income. The fund will continue to rise and then stop making half of its profits until the fund is sold. When the fund falls after reaching the expected return, investors can completely take profit.

Fund jiacang: after the fund loses money, it can add positions. For example, if the fund loses money to the jiacang point, then the investor adds money once and loses money to the jiacang point again, then the investor adds money again, and so on.
