There is no 7-day limit for index funds in the market, and the trading mode of index funds in the market is similar to that of stocks. The 7-day limit means that the fund is held for less than 7 days, and the redemption fee is charged at 1.5%. On-site fund sales only charge commission and no redemption fee.

The longer the OTC fund is held, the lower the redemption fee. The cost of on-site funds has nothing to do with the holding time, but only with the transaction amount. Therefore, OTC funds are more suitable for long-term investment, while OTC funds are relatively more suitable for short-term investment and have better flexibility.
