Binary Encoding

Binary encoding is the process of converting data into a series of bits and bytes that a computer can process directly without the need for parsing text-based structures. In the context of market microstructure, binary encoding is used to minimize the size of order messages, which directly reduces network latency and improves the speed of price discovery.

Unlike JSON, which uses human-readable characters, binary formats pack information into the smallest possible space, often using fixed-width fields. This is crucial for matching engines that must process millions of messages per second during periods of high volatility.

By reducing the CPU cycles required to parse incoming packets, binary encoding allows for faster response times in options trading and derivative settlement. It is the backbone of high-performance financial communication protocols.
