Under normal circumstances, after the end of the raising period and the opening period of open-end funds, the fund shares can be purchased and redeemed at any time within the specified time of the trading day of the stock exchange. However, when the fund continues to purchase and the scale continues to expand, sometimes the fund scale is excessively expanded. In order to protect the interests of investors, the fund company may take measures to suspend the purchase to control the further expansion of the fund scale. At this time, the fund is not open and cannot be purchased again. Similarly, fund companies may sometimes suspend redemption, so they cannot redeem.

Therefore, it can only be purchased or redeemed on the fund open day. The so-called open-end fund open day is the working day for investors to apply, convert and redeem open-end funds. The so-called fund working day is the normal trading day of the two stock exchanges. That is to say, under normal circumstances, the fund can handle business such as subscription, redemption and conversion on working days, but it cannot handle business such as subscription and redemption during the period when the fund suspends business such as subscription and redemption, that is, it is not an open day. Therefore, if you want to handle the above business, you must check whether the fund is in the open day period, that is, whether the fund suspends the subscription and other businesses. Otherwise, the subscription and other services are invalid.
