Install the necessary libraries<\/li>\n<\/ol>\nWhen you install Kiwoom Securities Open API+, dedicated DLL files that allow you to use <OpenAPI> are provided. To communicate with Python, you need to install the pywin32<\/code> library. To do this, enter the following command:<\/p>\n\n
pip install pywin32<\/code><\/pre>\n<\/div>\nHandling Login Events<\/h2>\n
The first step of the Kiwoom Securities API is to log in. The basic procedure for handling login events is as follows:<\/p>\n
\n- Initialize the API<\/li>\n
- Send login request<\/li>\n
- Check login success<\/li>\n<\/ol>\n
Initializing the API<\/h3>\n
To use the API, you must first initialize the COM object. Below is a basic code example for initialization:<\/p>\n
\n
import win32com.client\n\n# Initialize Kiwoom Securities API\nkiwoom = win32com.client.Dispatch(\"KHOpenAPI.KHOpenAPICtrl.1\")<\/code><\/pre>\n<\/div>\nSending a Login Request<\/h3>\n
Login is accomplished by calling the <CommConnect> method. This method opens a login window and processes the login. Below is the code for sending a login request:<\/p>\n
\n
# Send login request\nkiwoom.CommConnect() # Create login window<\/code><\/pre>\n<\/div>\nHandling Login Events<\/h3>\n
After sending the login request, you need to handle the information about the login result. You can check the login result using the <OnEventConnect> event handler. This event is called upon successful login and can be handled as follows:<\/p>\n
\n
class MyKiwoom:\n def __init__(self):\n self.kiwoom = win32com.client.Dispatch(\"KHOpenAPI.KHOpenAPICtrl.1\")\n self.kiwoom.OnEventConnect.connect(self.on_event_connect)\n\n def login(self):\n self.kiwoom.CommConnect() # Send login request\n\n def on_event_connect(self, err_code):\n if err_code == 0:\n print(\"Login successful\")\n else:\n print(\"Login failed, error code:\", err_code)\n\n# Example usage\nmy_kiwoom = MyKiwoom()\nmy_kiwoom.login()<\/code><\/pre>\n<\/div>\nActions After Successful Login<\/h2>\n
After a successful login, you can now make various requests through the API. Below is how to retrieve a list of held stocks after logging in:<\/p>\n
\n
def get_stock_list(self):\n count = self.kiwoom.GetAccountList()\n stock_list = []\n for i in range(count):\n stock_code = self.kiwoom.GetAccountStock(i)\n if stock_code:\n stock_list.append(stock_code)\n return stock_list\n\n# Example of retrieving held stocks\nprint(my_kiwoom.get_stock_list())<\/code><\/pre>\n<\/div>\nConclusion and Further Advice<\/h2>\n
In this session, we learned how to handle login events using the Kiwoom Securities API. The possibilities for automating stock trading through various API methods are limitless. It is also advisable to explore how to build automated trading algorithms using real-time data.<\/p>\n
Finally, remember that stock trading always carries risks, so be sure to conduct sufficient testing before proceeding with automated trading!<\/p>\n
