Fixed investment can not be stopped if it is not good, so the loss is even greater. On the contrary, it is more important to insist on a fixed investment at a low point. Of course, I don't think you can hold on. I suggest that you can redeem it when you reach the ideal value, but the fixed investment can still continue. You got it? Because redeeming the fixed investment does not mean stopping the fixed investment, for example, if you make a fixed investment in a bank, then the bank is your agent and invests the agreed amount at the agreed time. This contract is signed between you and the bank, and your redemption is an agreement between you and the fund company, so it is separate.
I think we can use the smiling face exchange method. When the fund you invest in is profitable, on the right side of the smiling face, you can start to consider redemption. According to my experience in investing in funds, you should start to consider redemption when the income reaches about 20%. 20% may also be high, so you can set yourself an ideal rate of return.
