Fund period: generally divided into three stages: subscription period, operation period (closed period) and subscription period. At first, it was a subscription period, usually about half a month. In this half month, you can only buy and cannot redeem (sell), and the buying price is generally 1 yuan. Then enter the operation period (closed period), during which the fund company takes your money to open a position, which can also be said to be the preparation period, which generally does not exceed three months. After opening, most of the foundation will increase, and some will fall back to 0.9* or lower. Don't think that you have lost money at this time, because your investment has just begun. Next, enter the subscription period, at which time you can buy and sell freely.
