The securities and stock trading interface is a software interface that can implement securities trading functions. It provides a set of functions or methods for trading. By calling these interfaces, you can perform operations such as buying and selling stocks, querying account information, and obtaining market conditions. The securities stock trading interface can be connected to the trading system of a stock exchange or a securities company, allowing users to conduct stock trading through automated programs or software.
Through the securities and stock trading interface, users can obtain real-time market data, personal account information, order transaction status and other information from the trading system, and can send relevant trading instructions through the interface call to conduct trading transactions. Such an interface can achieve fast, accurate and reliable transaction execution, improve transaction efficiency, and can develop and implement custom trading strategies according to their own needs. For example, the development document for multiple accounts to place orders in batches:
| Multi-account batch orders, distinguish each order by subscript |
|
| ClientId[] |
ClientId array |
| Category[] |
An array of entrusted categories, please refer to [Delegated Categories] for specific meanings |
| EntrustType[] |
An array of quotation methods, please refer to [quotation methods] for specific meanings |
| Gddm[] |
shareholder code array |
| zqdm[] |
Security code array |
| Price[] |
Order price array |
| Quantity[] |
Order Quantity Array |
| Count |
The number of entrusted items, that is, the length of the array |
| Result[] |
Array of entrusted results, each result needs to allocate 1024*1024 bytes of space Please refer to [Result format] for the format |
| ErrorInfo[] |
Error message array, each error message needs to allocate 256 bytes of space |
| None, whether the i-th commission is successful or not is judged by whether ErrorInfo[i] is an empty string |
|
Securities and stock trading interfaces are usually provided by securities companies or third-party institutions, and the specific interface forms and usage methods will vary, including but not limited to API interfaces, website interfaces, and dedicated software interfaces. Users need to make corresponding interface calls and data transmissions in accordance with the specifications and requirements of the interface provider to ensure the security and compliance of transactions.
Finally, the source code development of the stock trading pending order interface generally includes the following steps:
1. Determine the development environment and tools: According to the requirements of the interface provider, select a suitable development environment and integrated development tools, such as Java, C++, Python, etc.
2. Define interface parameters and return results: According to the interface documents or requirements, determine the parameters and return results of the pending order interface, including transaction type, stock code, transaction quantity, price, etc.
3. Connect to the trading system: Use the provided interface or SDK to connect to the relevant trading system and establish a communication connection with the trading server.
4. Realize the function of pending orders: According to the interface documents or requirements, write the logic of processing pending orders in the code, including generating pending order requests, sending pending order requests to the trading system, etc.
5. Processing the returned result: Receive the result returned by the trading system, judge whether the pending order is successful according to the returned result, and perform corresponding error handling or follow-up operations.
6. Error handling and exception handling: according to design requirements, handle possible errors and exceptions, such as network exceptions, server errors, etc.
7. Data encryption and security processing: According to security requirements, the transmitted data is encrypted to ensure the security of transaction data.
8. Unit testing and debugging: After the development is completed, carry out corresponding unit testing and debugging to ensure the normal function of the pending order interface and solve possible problems.
It should be noted that the specific development process and implementation methods may vary depending on the transaction interface provider and specific needs. The above is just a common development process reference. In addition, the development process must comply with relevant laws and regulations and the provisions of the exchange to ensure the compliance and security of transactions. Before development, it is best to communicate and confirm with the transaction interface provider in order to obtain more specific development guidance and support.
