Azhagesan-dev/order-flow-chart — reverse-engineered prompt

Build me a local web app for tracking NIFTY futures order flow in real time using my Angel One broker login.

I want it to connect to the live tick feed, turn that into candles and footprint style bars, and show an interactive chart in the browser. The chart should make it easy to read buying versus selling pressure with things like delta view, volume profile style display, dual side numbers, and imbalance highlights. Please also save tick data into a local SQLite database so I can reload history later, and include a way to import old tick data from CSV for offline analysis.

Add a simple but polished interface with live updates, date jump navigation, and saved UI preferences so it remembers my settings. Use the env file pattern for broker credentials and instrument settings, and make it easy to run locally on localhost. If there are legacy or better options for real time updates, pick the most reliable one. Look up current SmartAPI or Angel One docs online if you need to.
