IQFeed data NOT so true tick or is it?

Interesting I didn't know there were 3 feeds, although I suspect that most traders would not.

 

KR- If you are using Sierra there is a filter to set it you want to filter out bad ticks. The last time I compared TransAct and Sierra to Esignal the tick chart was almost identical.

 

Zen Fire is an unthrottled feed, atleast it was when I use it.

 

I believe IB is still snapshot data they don't show all ticks.

 

This was my understanding as well. It would like to know too if that is still the case.

 

I don’t trade Forex, sorry I have no idea.

How did you set up the fitters? I got mine on default. I didn’t want to screw it around as it might stuff up my data. But if I can get rid of the bad ticks from Transact (HUGE volume spike), then great, I might reconsider switching back to using the free data.

 

Here is a comparison data shot between Esignal VS IQFeed that someone has sent to me in PM – (Thanks).

Please ignore the missing data (48+4 "match until this point") that was missing on IQFeed, (I forgot to take out my volume filter before sending this person my screenshot). And from this source, I was told that Esignal uses RLC feed from CME. So I guess IQFeed is the only one so far that is using an aggregated data source. Good thing thus far is that IQFeed is hardly down in a fast market, it gets lag but not down. (Transact data was never down from my past experience).

 

I am not sure but if you go to the sierra support board someone can assist you.
