I need a compact, reliable script that pulls four data points—price, volume, open interest and strike price—for all live Nifty option contracts directly from the NSE website. The feed must refresh automatically every five minutes and deliver the latest snapshot in an easily consumable format such as JSON or CSV; I’m flexible on which one as long as it remains consistent. Please tap the official NSE endpoints where possible and handle any session tokens, cookies or anti-scraping quirks so the flow stays uninterrupted throughout the trading day. A simple configuration file that lets me tweak the refresh interval and output path later on would be ideal. Deliverables • Well-commented source code (Python preferred, but I’m open) • A brief README covering setup, dependencies and how to run the job on Windows or Linux • Sample output file generated from a live pull • Proof that the script loops successfully over at least one full market hour without missing an update If you’ve built market-data collectors before—especially for NSE—let me know; that experience will be a big plus.
