The band operation of the fund is mainly based on the net value of the fund, or buying on dips and selling on rallies. When the net value of the fund falls to the previous low level and is supported, investors can consider buying moderately, while when the net value of the fund rises to the upper high level and is suppressed, investors can consider selling.

Fund band trading is suitable for floor trading, with low handling fee and no printing cost. Generally, the round-trip handling fee of 10,000 yuan is around 6 yuan. Some brokers can buy on dips at the opening time and sell later, so that they can buy other on-site funds immediately. If they need it, they can transfer it to their bank card the next day. Off-site band funds utilization rate is not high, and the handling fee is high. Some T+4 redemptions arrive the next day or even longer.
