Oh, I've never seen anyone buy and sell stocks like this. The price at which you buy the pending stock is the actual price, and the cost price is simulated by the trading software of the brokerage firm. To buy stocks, if it is lower than the minimum fee standard of brokers, it is generally 5 yuan. For example, your total amount is 1290 yuan, which is usually the commission (handling fee) of 5 yuan, followed by Shanghai and transfer fees. In addition to the handling fee, there is also a stamp duty of one thousandth.
