I’m building an end-to-end trading platform that streams live market data and lets users act on it instantly. The heart of the site is a wallet-based login system that holds only cryptocurrency for now, so every interaction—from authentication to funding and withdrawal—flows through crypto addresses. What I need built: • A real-time market feed that pushes accurate price updates to the browser without refreshes. • Interactive price charts (candles, depth, indicators) that redraw smoothly as new ticks arrive. • Instant trade execution tied to those live quotes, with order status updates pushing in real time. • A personal dashboard where each logged-in user can track open positions, P & L and historical trades. WebSocket or similar streaming tech will be essential, and I expect clean API integration with at least one major exchange so we’re not reinventing a matching engine on day one. Modern stacks such as React or Vue on the front end and Node, Python or Go on the back end are preferred, but I’m flexible if you can justify an alternative. Security, rate-limit handling and responsive design should be baked in from the outset. I’ll share wireframes, exchange API keys and detailed workflow diagrams once we agree on the collaboration terms. Final deliverables are the full source in a private repo, a staging URL, deployment scripts and a succinct setup guide so I can spin it up on my own infrastructure. If you have proven experience with live-data apps, websocket optimisation and crypto wallet flows, let’s talk and get this trading site online.
