1Challenge

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.

2Solution

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.
