I’m looking for a quick-turnaround MVP that connects to Broker A’s API (credentials and docs supplied) and lets me view and act on an options chain. Core requirements • Authentication: Creating Access token through broker API. • Options chain: pull live data for a chosen stock or index and present it in a clean table format (strike, expiry, bid/ask, Greeks, etc.). • Trading actions: Buy / Sell for CE and PE directly from the table, passing the order to Broker A. • Position view: show open positions in a separate table with P/L updating in real time. • Payoff chart(High Charts): visualisation of potential payoff for the current position with real update of Option metrics. Tech expectations Feel free to use modern, rapid-dev tools—React or Vue on the front end, Node.js, Python (FastAPI, Flask) or similar on the back end—whatever lets you produce a clear, maintainable codebase fast. Simple styling with Bootstrap, Tailwind or Material UI is fine; no heavy theming needed. Deliverable A lightweight, self-hostable web application (source code + brief setup guide) that demonstrates the above features in working form. I’m after a functional proof of concept rather than a polished product, so focus on clean code and reliable API calls over fancy UI extras.
