When the fund is profitable, the unit price will decrease after selling, and it will increase when losing money. If you buy another one when the fund is down or low, the cost will be diluted and your unit price will be reduced. The more you buy, the more your cost will be reduced. Of course, considering the risk, you can't buy too much at once.

The fund position cost is confirmed at the time of purchase and will not change after confirmation. The cost price of fund position generally refers to the price after adding the handling fee when buying the fund. You can check the position cost directly in the fund position.

Precautions:

After redeeming half of the fund every day, it will increase the yield according to the diluted cost. Since I can't support the average cost calculation, I think of a good method, that is, rate of return = position income/(total fund position-position income). If the fund has not been sold at one time, it does not need to be converted according to the original calculation.

T+ 1 trading of the fund, buy on the same day, confirm the share on the second trading day, and calculate the income after the share is confirmed. Trading hours are: 9: 30am-1:30am from Monday to Friday, and1:30am in the afternoon-15: 00pm. Trading is not allowed on legal holidays.
