Brokerage commission is a way for brokers to collect fees for customers to operate securities. When customers buy and sell securities, brokers will charge a certain percentage of commission according to the transaction amount. The idea of split warehouse means that if customers open securities accounts with multiple brokers at the same time, brokers will calculate the commissions of different accounts separately, which is the concept of split warehouse commission.

The implementation of brokerage commission can bring diversified investment effects to customers. Because for different securities markets, different brokers will have their own resources and strategies. Customers can get more investment advice and more comprehensive market information by opening securities accounts in different brokers, thus improving the probability of successful investment.

Although brokerage commission improves investment flexibility, it also makes commission calculation more complicated. In order to avoid the inconvenience of multi-head brokers in calculating commissions, customers are advised to concentrate their operations among different brokers as much as possible. If the customer has opened multiple brokerage accounts, it is suggested that the investment strategy and the judgment of a securities market should be coordinated and managed accordingly. So that the warehouse-dividing operation can be carried out smoothly and the commission cost can be reduced.
