Research Computing >> Data >> CME Selective Time & Sales




The CME Selective Time and Sales data (CME tick data) can be accessed by Kellogg faculty and doctoral students in skew3. The files are in flat ASCII format, stored in skew3 in the /kellogg/data/cme path.

The files can be read with any statistical or mathematical software.


The CME Selective Time and Sales data covers the period between April 21, 1982 and June 30, 2000, tick-by-tick. The commodities included are S&P 500 options, futures and cash index. The latter would best reflect the value of the underlying futures and options market. Variables in the dataset include delivery date, price, strike price, time, trade date, ask/bid indicator and trade sequence number, among others.
