Everyone blames volatility for crypto’s instability. But the real problem runs deeper. That is fragmentation. Each exchange speaks its own language. Different APIs, rules and latency quirks. What looks like one market is actually a fractured maze. And that’s where serious systems start to break. If you have ever tried aggregating order books from multiple exchanges while running trading strategies in real time, you already know that the challenge is not writing code.

In this blog, we will explore how to design a system that integrates multiple exchanges, standardizes data and executes trading strategies reliably. It is by using Node.js, RabbitMQ and a scalable AWS Architecture. Along with enabling automated execution through Algorithmic Trading Bots.
