Brokers usually handle securities reservation requests according to the loanable quantity of stocks and market demand. If the loanable amount of a stock is limited, or there is a great demand for securities booking in the market, your chances of successfully booking securities may be very low. In addition, brokers will also consider your account capital status, credit rating and other factors.
Usually, brokers will provide customers with some information about securities contracts, such as the amount of loans, borrowing costs and so on. This information can help you judge whether the reservation is likely to succeed, but it does not necessarily provide a specific probability of success. If you have specific questions about margin trading, it is recommended to consult your brokerage or financial professionals for more detailed information and suggestions. Brokers usually provide documents about the policies and procedures of margin trading. You can refer to this information to understand the specific details of securities cancellation.
