Out-of-the-box fully standard FAST 1.1/1.2 Encoder and Decoder implementations.
FAST (an acronym for FIX Adapted for Streaming) is a binary compression algorithm optimised for real-time distribution of high-volume market data. It was developed by FIX Protocol Ltd (FPL) to reduce the bandwidth requirements and the latency of message oriented data feeds.
