Automatic Generation Algorithm of FAST Protocol Templates for Efficient Transmission of Financial Data

The protocol FAST (FIX adapted for streaming) is superior than FIX in that it performs data compression according to the protocol template prescribed. Since the FAST protocol template captures the sequence characteristic of the transmitted data, it is written manually by human experts. This paper describes an algorithm for generating FAST protocol templates automatically by analyzing the patterns of message sequence. The experimental result shows that the proposed algorithm is slightly more efficient than the human expert in respects of the compression ratio.
