Why is TT data so bad?

CQG Data
CQG receives its data directly from the exchanges. Immediately after CQG IC has been enabled, the system begins collecting and displaying real-time data from the CQG network.

This data is continually monitored to filter out bad ticks. When bad ticks are detected, corrections are immediately processed. Likewise, when inserts, deletions, and fast market indications are received, the system immediately sends them to your system.

In the event of an interruption in the operation of the software or the data source, the system automatically corrects the data and fills in the gaps that occurred as a result of the interruption.

Could you please explain what you mean by "cogent line" and "members sonet loop"?
Thank you!

I see now what you mean. One could argue if that is a good thing or a bad one. Filtering isn't about getting rid of bad ticks. It's about latency and completeness (accuracy). If all they do is what you have posted above, then I am fine with it. But thats maybe different for other users.

I have had good experience with TT, Rithmic and CQG. TT and Rithmic have some advantages, for example they offer Level 3 data, something CQG is not offering yet.
But still, for my short term trading, Sierra Chart + CQG is the best combo I have used so far. But I can understand that other users have different preferences, it seems to be pretty individual. I have heard people complain about problems with their CQG feeds (disconnections, lags ...), problems that never occured in my CQG setup.

my experience with tt is that is by far the fastest of all feeds equal to the old globex terminals members had. i was able to compare them in the old cme building on direct members fiber optic feed to members servers.

so it's all about your connection as much as the data company. in side by side tt will beat anything when connected to the same routes. you can't compare tt connected through a brokerage that may be on a cogent line or something with the members sonet loop in chicago.

cqg will always be slower because they correct data on the fly with an algorithm and always have. also they will change data in historical so real time execution of an algo may put you long but in history it will show a short.

there is much more to all this than most people know or are willing to study. as someone who has lost millions due to errors "i am the error king of knowledge". very few have witnessed live disasters at large trading organizations more than i have. cqg is probably the best fastest compromise of data there is but tt is faster given the same set of parameters.

i love to hate both really - they are both good companies who will shove down your throat what they want you to have not what you want.

I appreciate your thoughts on this. i would agree with you that TT is the fastest feed. BUT I would also argue that they are able to achieve this precisely b/c they don't put care into making sure the datafeed is entirely accurate. If all you need is Level 1 data + market depth on DOM + number of trades + overall volume, then TT is perfect. But with so many traders now requiring accurate bid and ask volume data to perform orderflow analysis, TT suddenly becomes useless.

we all knew this was the case with TT for years now but i only wanted to make this post, not to complain or hate on TT, but because it's in my interest (and all traders' interests) to have many competing datafeed options that can bring down costs for everyone.

in the current climate, TT datafeed is automatically a no-no for any traders performing orderflow/volume analysis. so there aren't that many other feeds to choose from. TT having a more accurate datafeed would be a plus for everyone, including TT.

membership has privileges, around exchanges for a few miles "at every exchange" they have a sonet loop "dedicated fiber" in proximity to the exchange for offices of traders who are members of the exchange to get the data before you get the data.

a cogent line is a low cost high speed data line that most non-exchange members use to get their data which is sub-standard from a trunk line from a major carrier like att.

you can't have it both ways is tt and cqg attitude. fast and unfiltered or filtered slightly compromised. depends on the micro scale of your trading. if you need super fast you need to be an exchange member and office within the ring with a direct connection the members server.

I think clarification is in order here. I am quite sure this direct quote related to CQG IC (Integrated Client) which is their desktop platform. Meaning, the post processing of data is occurring client side and not server side. So the CQG data feed consumed by many third party applications, including NinjaTrader, is raw and unfiltered.

Are you sure about this ? I was reading their description here:
http://help.cqg.com/cqgic/default.htm#!Documents/cqgdata.htm

From this text to me it is unclear if the filtering/correction/"massage" of the data is happening already on their server side, or only in the individual trader's CQG IC platform (client side).

I am 100% sure. Then I checked with CQG for good measure and they indeed confirmed. Real time data is unfiltered. The post processing they refer to in their reference guide is for historical data.
