The redemption time of OTC index funds is generally 1-3 working days, and the longest is no more than 5 working days (depending on the product). On-site index funds arrive in real time and can be transferred out on the second trading day of the day.

Off-exchange funds are purchased on sales platforms (Tian Tian Fund, Alipay, WeChat, banks and brokers), while on-exchange funds need to open an on-exchange fund account to trade (brokers open accounts). Index funds buy the constituent stocks in the index. Index funds follow a specific index and buy some or all of the stocks in the index in order to obtain the same income as the index.
