How can the fund stop falling after buying it? In this case, you can set a tracking take profit point. For example, after the fund is bought, it rises by 20 points, that is, it has a yield of 20% at this time. At this time, the tracking take profit point is set to 15%, that is, if the fund falls later, it will take profit when the rate of return returns to 15%, otherwise, if the fund does not return to 15%. Setting a tracking stop profit point can protect profits when the fund takes back profits.
