Author	Topic: Iqfeed Total Volume Vs Emini S&P Time and Sales Globex? (2 messages, Page 1 of 1)
senator -Interested User- Posts: 22 Joined: Jul 5, 2004	Posted: Jul 7, 2004 06:10 PM Msg. 1 of 2 I wonder, how can I compare if the total volume traded I recieved from Iqfeed on the e-mini S&P matches the Volume posted on the website of the CME Time and Sales of Globex during a particular day? Since I dont understand what update different that the t, T, b or a....... is happening with the o caracter? I cannot know whether it could be a real trade or what? The HH represents the hour of the day in a 24 hour clock. MM represents the minutes of the hour. The character represented by c indicates one of the following: t - A trade update occured T - Extended Trade. b - A bid update occured (an ask update may also have occured) a - A ask update occured o - Some other type of update occured Could it be possible that if the o caracter appears it could mean there was a trade?

The o character could not mean that there was a trade. The most common reason for an o update is a volume update due to a correction. Thanks! Natalie Hannan DTN Market Access, LLC.
