It is not recommended to buy a full position when buying a fund at the bottom. The risk of a full position is high. When investors are full positions, if the fund rises, they may get the maximum profit. If the fund continues to fall and reaches a new low, there will be no extra funds to cover the position.

This will cause investors to suffer huge losses, and even lead to deep traps.

When investors are at the bottom of the fund, they can choose to buy part of the fund online, and then slowly increase their positions when the fund rebounds. At the same time, they can set take-profit and stop-loss positions to control risks within a certain range.
