There are many people buying funds now, and they only sell a certain share every day. After queuing for a long time, I couldn't buy it. This would only happen if there is a subscription limit for newly issued funds. As long as you open the subscription for open-end funds, you will generally be able to buy them. It is very convenient to open online banking and buy and sell online. If it is easier for you to find someone you know at the bank, that would be better.
