Today I crosslink to my article Simplifying Market Tick Data Management as originally published to Finextra on 12 August 2016.
“For my first post, I thought I’d look at some of the issues that exist around managing trading data. After all, market trading generates phenomenal amounts of data. The NYSE, for example, saw more than 3.17 billion trades on the 18th of December 2015, with a value of over $110 billion. The NASDAQ has more than 2,000 equities that are being actively traded. As each market trade takes place, banks and financial services institutions have to ingest and track these transactions over time. The volume of trades for each equity can reach up to a few million ticks per single day, and exponentially more for equity options; multiply this across multiple stocks and exchanges, and the volume of data created over time is vast.”
