Real-Time Performance Inquiry and Trading Decision Support System

Project Overview:
Develop a Windows application that can automatically scan a specified website, scrape usernames, and use these usernames to perform real-time performance inquiries on another website. The system will automatically support trading decisions based on the inquiry results and predefined filtering criteria.

Specific Requirements:

1. Data Scraping and Processing:
• Automatically scan and scrape usernames from a designated website.
• Use the scraped usernames for real-time performance inquiries on another site.
• The system must be able to handle usernames and related numeric data.
2. Trading Decision Logic:
• Decide whether to display buy or sell signals based on performance inquiry results and predefined filtering criteria (to be further specified).
3. User Interface Design:
• Provide an intuitive and easy-to-operate graphical user interface.
• The interface needs to display real-time data inquiry results and provide clear buy or sell signals.
4. Technical Requirements:
• The application should run stably on Windows platforms.
• Considering data security and stability, the application needs to have error handling and data protection mechanisms.
