TradeView Pro
Real-Time Multi-Exchange Trading Dashboard
TradeView Pro is a real-time multi-exchange trading dashboard with sub-second end-to-end latency, interactive candlestick charts, portfolio P&L, and a custom alert engine with webhook delivery — TypeScript, React, WebSocket, Node.js, Redis, and PostgreSQL.
// the problem
Challenge
Traders need unified views across multiple exchanges with zero lag. Each exchange has different protocols, data formats, and rate limits. Building a reliable aggregation layer that normalizes data while maintaining near-instant latency requires careful architecture.
// what we built
Solution
TradeView Pro connects to multiple exchange APIs through a custom aggregation layer. Data is normalized into a common format, cached for historical queries, and broadcast to clients in real time. Interactive candlestick charts render with smooth pan/zoom. Custom alerts trigger on price, volume, or technical indicator thresholds.

Frequently asked questions
How does TradeView Pro achieve sub-second latency across exchanges?
A custom aggregation layer connects to each exchange's WebSocket feeds, normalizes messages into a common format on the fly, caches them in Redis as a time-series, and broadcasts to clients over WebSocket — end-to-end under one second.
What exchanges and assets does it support?
Multiple major exchanges through pluggable connectors, with data normalized so the frontend works identically regardless of the underlying venue.
What technology stack powers the dashboard?
TypeScript and React on the frontend, Node.js for the aggregation and alert engine, WebSocket for real-time streaming, Redis for time-series cache, and PostgreSQL for historical and relational data.
How do custom alerts work?
Users define price, volume, or technical indicator thresholds. The alert engine evaluates every tick against active rules and fires webhook notifications to the user's configured endpoint when conditions trigger.
Can TradeView Pro track portfolio P&L?
Yes — the platform aggregates positions across connected exchanges into a unified portfolio view with real-time mark-to-market P&L and historical trade export.
