What Tiantian Fund publishes online is the net value, while what the securities companies publish is the market price. The market price is affected by supply and demand, and the net value is only related to the assets of the fund company.
Just like a commodity, the value of the commodity when it is manufactured by the factory is the net value, and the market retail price is the market price. In short, in a nutshell, what Tiantian Fund Network announces is the value of factory-made commodities, while securities companies
is the retail price of goods in supermarkets.
When you buy and sell in the stock market, it is the price of the securities company. If you "subscribe" or "redeem" at the securities company, Tiantian Fund Network, or bank, it will be the net value published by Tiantian Fund Network.
Finally, I would like to say that only securities companies have "on-the-counter funds", and Tiantian Fund Network does not have "on-the-counter funds".
