Building a real-time multi-exchange charting platform with QuestDB

Arden Charts was developed to address the need for continuous, multi-exchange market data coverage, which is often lacking in standard charting platforms. The platform's architecture consists of microservices that handle data ingestion, processing, storage, and querying across multiple exchanges, such as BinanceUS and Kraken, using QuestDB as its backbone due to its efficient handling of time-series data. By employing a lightweight pub/sub layer with NATS and utilizing Redis for fault tolerance, Arden Charts ensures real-time data processing with minimal resource usage. QuestDB's materialized views facilitate efficient data aggregation by pre-computing various timeframes, thus optimizing the real-time charting experience. Historical data is sourced from Massive.com and integrated through a reliable ingestion pipeline. The platform's design emphasizes scalability and efficiency, demonstrating the effective integration of tools like NATS, Redis, and QuestDB to deliver seamless, real-time charting with comprehensive historical data access.
