I bought Jiashi on the 30th, and the price is stable, 10000, and the handling fee is 150. Actually, I only have 9850. I would like to ask what is the net value to protect the capital, that is, 10 150.
The harvest you bought on the 30 th was very stable, and it was broken into one yuan that day. According to the figures you gave, you should * * * buy 10000 yuan, minus the handling fee of 150, leaving 9850 yuan, which is 9850* 1.00.
=9850 copies. As long as the net value of the fund is higher than one yuan, it is earned.
Above 10 150 yuan, the net value must be equal to or higher than 1.030 yuan.
