About SBE

Simple Binary Encoding (SBE) is a FIX standard for encoding binary messages developed by the CME Group and the FPL High Performance Working Group, which aims to optimize the exchange of financial data for high-volume, low-latency data dissemination. Compared to FAST (old encoding standard) it is simpler and faster to encode and decode.
