The shares of the fund's fixed investment can be redeemed at any time, and these shares have nothing to do with the fund's fixed investment itself. Because the fund's fixed investment generally stipulates the buying rules: for example, on a certain day of each month, a fixed investment fund is purchased at a certain amount, which is the buying rule of the fund's regular fixed investment. Under this set of rules, there is no selling rule.

If the open-end fund is not a special type that stipulates the redemption period or redemption conditions, most of it is impossible to limit redemption. This is also the basic feature of open-end funds.
