If investors are at a loss at this time, they can make up their positions, which will reduce the cost of investors. The lower the cost, the better. The lower the cost, the lower the risk that investors bear, and the higher the probability of returning to capital or making profits in the future. It should be noted that it is not possible to open positions at one time, and investors can make up positions in batches.

If investors are profitable at this time, there is no need to make up positions, which will increase the cost of investors. The higher the cost, the higher the risk that investors take, and the greater the possibility of future losses.
