Fixed investment in funds is a strategy of investing in funds. After the fixed investment is set, the system will buy the fund in a fixed amount on a regular basis, without manual operation by investors. The characteristics of the fund's fixed investment are saving time and worry, general income, untimely timing and no stop loss.

There are daily, weekly, biweekly and monthly fixed investment. Different fixed investment time has different benefits. The higher the frequency of fixed investment, the more average the cost and the more average the future income. The longer the fixed investment time, the smaller the income gap will be.
