The amount is not equal to the minimum subscription/subscription amount plus an integer multiple of the transaction level difference. It should be that the subscription amount you submitted does not meet the requirements of the fund company. First of all, general funds have a minimum subscription amount. In addition to the minimum subscription amount, a trading range will be set, that is, the amount you submit must meet both the minimum subscription amount and the trading range. For example, if the minimum subscription amount of Fund A is 1 1,000 yuan and the trading range is an integer multiple of 1 yuan, you cannot submit 500 or 1, 0 1 and so on.
