Product Review: Unfair Advantage by John Sweeney
You may have thought all data these days resided on giant servers and only came to your machine when summoned. Not so! Those who study prices over time usually require the data on their own machines to facilitate their studies. Many vendors supply this need. Of those, Commodity Systems, Inc., is one of the most respected.
CSI started when statistician Bob Pelletier set off to get decent data for his own trading. Not satisfied with what he found, he started his own company and brought to
it his own desire for precision and detail. The result was to create the most thorough, detailed, and accurate data service available. Unfair Advantage is the culmination of that process.
