Choose stocks with good trends, first intervene in 30% positions, then add 30% positions after intervention, and the remaining 30% positions can be moved with high sales and low absorption.

Of course, for some stocks, you can also intervene in the whole warehouse at one time. After pulling up to a certain extent, you can reduce your position to 60%, which is equivalent to locking in profits. However, this method is suitable for retail investors with certain trading experience. If a novice does this, there is a certain risk.
