I require a web-based Order Management System that allows me to work with multiple brokers from a single screen. Its core features should include: robust order tracking, order punching, order management, money management, real-time data synchronization with every connected broker, and an in-built mechanism to share messages or notes with each broker without leaving the platform. My requirements are as follows: Brokers: Upstox, Alice Blue, Angel One, Dhan, Groww, Shoonya • A browser-accessible interface usable on any modern desktop or tablet. • Reliable, real-time feeds ensuring that positions, fills, and status updates appear instantly. • A backend architecture capable of scaling as new brokers are added, featuring clear REST or WebSocket APIs for future integrations. • Secure login, role-based access, and an activity audit trail. • Direct messaging between brokers (chats or threaded comments linked to each specific order). Acceptance Criteria: • During testing, the ability to place, modify, and cancel orders—with confirmation—across at least three live broker connections. • The dashboard must update within a few milliseconds of any order event occurring. • All communication logs must be stored and retrievable via the Order ID. • Upon project completion, deployment instructions and the source code must be handed over. If you possess solid experience in building trading or FinTech web applications that rely on real-time data, let's discuss your approach and timeline.
