Nifty50 Real-Time Screener Build

I need a bespoke, full-stack stock screener focused exclusively on the Nifty 50 stocks and other nifty 500 stocks as well. The tool must stream real-time quotes while retaining the ability to look back through historical data so I can validate strategies before I deploy them...
