If you ever spend some time comparing, it will become easier and easier to believe. Two different feeds will differ quite often. In addition, many people don't realize that two setups with the same feed provider will have differences in their data in some cases. Decent feeds are like a Monet... stay away from feeds that are like a Picasso.
Can you help answer these questions from other members on futures io?
It depends on what you want. Generally a 5-minute chart of price is going to be practically identical between good data feeds. It's only when you decide you want to know about all the trades that you start having to scratch your head. From what I've seen, it's probably safest to use a methodology that doesn't hinge on you knowing exactly what took place in the market, because it's apparent on investigation that you can't get that kind of precision from everyday data feeds.
I've not used IQFeed... lately I've found that my barchart.com feed has a lot more tick data in it than my Zenfire (example: Move the Markets • ZenFire vs. Barchart.com feed). For most purposes, eSignal, ZenFire, Tradestation, and Barchart.com have all been acceptable to me, with TS being the most questionable of them. As a point of interest, I found I got more and better data from eSignal when I connected from my parents' house in Oklahoma than when I connected in Texas. No wonder my clients from around the world kept complaining their charts didn't match mine! I did not care for TransAct or IB feeds, and would not personally use them again.

I have IQfeed and Zen side-by-side. IQfeed has far, far FAR more "updates" (ie: bid/ask, dom) than Zen Fire, but is a fraction of a second slower. I can see Zen tick a 'last' price a fraction of a second sooner than IQfeed will.
So it will depend on what is more important, complete picture of bid/ask but very slightly slower feed, or incomplete picture of bid/ask but slightly faster feed.
It seems eSignal has been going down hill lately. Barchart is becoming more widely accepted for retail lately it seems, I've not used them. Based on my own personal experience, I would still rank it 1) Zen Fire, 2) IQfeed, 3) eSignal. But if bid/ask is important, then IQfeed is #1.
Thanks Mike and Richard.....I use bid and ask so I'll give IQFeed one more try to see if it makes difference on my end..
at first IQFeed had me on some sort of simulated feed trial without even telling upfront so I have no clue what I demoed....I wonder what else are they not telling me.....barchart was randomly disconnecting in NT6.5 and they suggested I should work with NT on solution.......hmmmm, who is paying who here.....esignal was trying to sell me everything but the feed alone......I ran out of time ....or patience, forgot what happened first, so I moved on........
looking to short 6E down to 1.3400......it's at 1.3427 I think.......
After you contact IQfeed I'd like to hear what they say. If you don't get resolution on this for sure let me know, I'll see if I get a different answer. Please contact IQfeed and see.
Hi Mike.....my reason for wanting IQFeed is to have a place to go to when I need my Gom files updated.....I followed Gomi's recommendation and decided to try IQFeed+QCollector combo....I was not getting any Ask/Bid in QCollector and wondered if there is an issue with the software.....below is the response I got from Dave DeLuca.......now, I understand if I was not getting Ask/Bid values because they had me on simulated feed but Dave was not getting those values either.......
