Q1:  Why are there zeros in the price column, followed by volume figures?
A1: If there is a zero in the price column and an asterisk (*) appears in the time bracket column, the volumes are the accumulated CME Globex  totals. If there is a zero in the price column and nothing appears in the time bracket column, the volumes are accumulated spreads and cash for futures.

Q2: Why doesn't the volume listed in Volume by Price match the volume shown on the Ticker?
A2: Volume by Price does not contain Cabinets, Transfers or As Of Trades (outtrades). Ticker volume does not include cash for futures. Therefore, the ticker volume will always be approximately 5% greater than half of the Volume by Price total. This is also the approximate percent of outrades we have daily.

Q3: What is the difference between Volume by Tick and Volume by Price?
A3: Volume by Tick includes all available ticks, including those ticks that had no volume traded that day. Volume by Price has data only for prices where volume exists.

Q5: What contracts will be listed in the Volume by Price file?
A5: The basis of selection for contracts for the Volume by Price file will be:

Futures - The newest and oldest open contracts for a futures commodity with open interest of 1,000 or greater will be selected, along with all contracts between those two.

Options - The open interest for all strike prices of an option contract (both puts and calls) will be added. If the total is 1,000 or greater, that option contract, including all strike prices for both puts and calls, will be selected.

These files are compresed (zipped) files that you will need to save to your hard drive and then uncompress (unzip) with a program such as PKZIP or WinZip.
