I want to pull live horse-racing odds from Sportsbet, feed them into a small Windows desktop application, and have that app highlight the percentage change in those odds at user–defined intervals (for example every 30 seconds, 1 minute, 5 minutes, etc.). The workflow I have in mind is straightforward: a background scraper grabs the latest market prices from Sportsbet, the data is stored locally in a lightweight database or cache, and a front-end window immediately visualises each runner’s current price alongside the change since the previous poll. A simple colour cue or up/down arrow is perfect—nothing overly complicated, just clear, real-time insight into market movement. Please build the whole stack—scraper, data layer, and Windows GUI—so I can run it from my PC with a single executable or installer. Python with Selenium, BeautifulSoup or Playwright is fine (open to your suggestion), and a clean desktop interface built with PyQt, Tkinter, Electron, or similar will work. The critical part is reliability of the scrape and clarity of the percentage-change display. Deliverables: • Source code for the scraper and desktop app • Compiled Windows build or installer • Brief read-me explaining setup, interval configuration, and how to add further Sportsbet markets in future Acceptance criteria: odds update at the chosen interval without manual refresh, percentage change calculation is accurate, and the UI loads on Windows 10/11 without dependency issues.
