Subscription is the purchase of issued funds, and the purchase follows the principle of "unknown price". That is to say, when you buy and sell open-end funds, you buy them by a certain amount, that is, you want to buy a fund of 1000 yuan, but you don't know how many copies you can buy and how much each one costs. When you sell funds, your share is certain, that is, when you sell, you sell 1000 funds, but you don't know how much each of these funds sells.
The specific rule is to submit the application before the trading day 15: 00, and take the net value of the fund on that day (calculated after the market closes at 15: 00) as the transaction price; If it is submitted after trading day or non-trading day 15: 00, the net value of the fund on the next working day shall be the transaction price.
