Toward Real-Time High-Frequency Stock Monitoring System Using Node.js
Investing in stocks is a very popular financial management for modern people. Accurate data is aided for investor to make better decisions. But there are some challenges to design such a real-time system to present high-Frequent data. This paper introduced a solution toward real-time high-frequency stock monitoring system. The architecture, process and implementation of this system are presented respectively. This system is better in real-time monitoring, distributed services, high degree of concurrency, and interactive user experience using cache, load balancing, and CDN techniques. It is evaluated that Node.js performed well with advantages of its single thread event-driven mode and asynchronous I/O when it was in the environment of high concurrency.
