According to Cai Xi. Com, the fees charged by securities companies when conducting transactions are calculated in proportion to the transaction amount. Specifically, every stock with a turnover of 1 10,000 yuan needs to pay 2.5 yuan's commission. If a single transaction is dissatisfied with 5 yuan, it will be charged according to 5 yuan.

After opening an account, investors can negotiate the commission rate with the securities company according to the amount of funds. Generally speaking, the more funds in an investor's stock account, the greater the decrease in commission.
