Either way, investors can buy it once or every day. You can open a fund to make a fixed investment every day, and you can set it as a fixed investment every day.

One-time buying is suitable for investors who have frequent trading and certain trading experience, while fixed investment is more suitable for investors who have no time to watch the market and have no trading experience. Compared with fixed investment, fund purchase has the advantages of saving time and worry, taking average income, and no need to stop loss at the right time.
