IQFeed data NOT so true tick or is it?

Quote from iqfeed:

What you are seeing is aggregation at the exchange. The exchange has 3 different feeds currently, and depending upon which feed the vendor/broker is on you may see different levels of aggregation. We are currently on the ITC feed from the exchange. We are in the process of moving to their Fix/Fast feed which we are told has little or no aggregation at the exchange. I can assure you DTN sends every trade we get from the exchange.

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.

I was under the impression that pretty much all data feeds are throttled. I know as fact that the TT data is (ok, not a data vendor).

If every tick and depth change was to be transmitted, your bandwidth would croak. Besides, the human eye can only register or 'see' something like 4 updates a second. Do you really need to see every tick?

As for the Fast CME feed, well thats really only of use to black box traders who are co-located near the exchange and can actually process the information.

The Zen Fire feed is unthrottled at least it was when I used it. It's the fast feed I have seen.



ProfLogic: Interested in your CVB's. I still use time bars and volume plot underneath when using charts. I like to look at volume as a sentiment gague (like most I imagine). What would you use for this? Just the length of the bar, or perhaps tick bars to see how many trades it took to produce your volume?...

(Another thread perhaps?)

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

Thanks for turning this stone over.

Can anyone tell me how IB's feed now compares with the others since Globex started consolidation; or comment on its speed. I sometimes have trades reported as filled as much as a second before the price shows as reaching my limit order, which is a little disconcerting.

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.

Do you know if zenfire is available for Forex??

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.
