I already have my Kotak Neo API credentials working on an Ubuntu-based AWS EC2 instance and can log in successfully from Python. What I need now is a small but reliable web application, hosted on the same EC2 box, that will let me trade from a browser instead of the command line. Core user flow • The landing page should stream BOTH Nifty and Sensex options chains in near-real-time. • From the chain I want a clean Buy / Sell button that instantly sends the order through the authenticated Kotak Neo session. • A separate panel must allow one-click strategy tickets: Straddle, Strangle and Iron Condor (entry as well as the automatic pairing of legs). • Once an order is fired, the app should display current positions, the exact fill details and give me a Square-Off / Close button for each open position. Tech environment The EC2 instance runs Python 3.10. Feel free to use Flask, FastAPI or a lightweight Django setup for the backend; WebSockets or SSE for live data push; and a minimal React/Vue/Plain-JS front end—whatever lets you deliver a fast, responsive UI. All secrets will live in environment variables and I will handle the SSL certs and domain. Deliverables 1. Source code with clean README explaining setup, env vars and deployment commands. 2. A requirements.txt or Pipfile plus a simple systemd / supervisor service file so the app survives reboots. 3. Brief test script that demonstrates a dummy order to the Kotak Neo sandbox (or live if sandbox isn’t available). 4. Short video or screenshot walkthrough confirming: options chain display, manual Buy/Sell, Straddle-Strangle-Iron Condor ticket, position view, square-off. Acceptance criteria The dashboard must execute a Straddle on Nifty, show both legs filled, and let me close them from the UI without shell access. If something in this flow is unclear, let’s sort it out before you start coding—I’m ready to move quickly.
