The CME Volume by Price file is made available in the early evening. The files are named vpyymmdd.zip. Inside each Zip file is a text file named vpyymmdd. For more information about this file, please see the Volume By Price FAQ. Each file contains a record of total volume for each contract at each price for the trading day.
Effective 9/1/04, the Volume by Price FTP files no longer contain CTI data.
CME made a small change by adding the Expanded Commodity Code field to the Volume by Price FTP file on 9/23/05. The updated file layout guide is reflected below.
