"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe
"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

Hi Sergi,

All should be repaired at this point. We are actively watching for problems on these symbols, and working with the data provider to prevent future problems.

Hi Sersan,

I am not seeing any issue with the LFZ8 data on either server farm. I have looked at 1 minute, 5 minute, 10 minute, and daily charts. Can you specify what exactly you are seeing? If you can give me an idea of what you are seeing, perhaps i can duplicate it. Are you still seeing delays in the data?

This has been a continual problem since August? Does this occur every day, week, etc? I went ahead and sent this over to our Market Data group, however, whatever information you can provide will be helpful. I would like to get this resolved once and for all.

Kind regards,

Hi Lbfvt!

So sorry for the delay in response, I've been out of town and I guess people were sleeping on the job : )

It looks to me like FVX.XO has been updating correctly starting at 9:29/9:30 based upon tick data I can pull through. Our market data group has confirmed this is correct, but I will do a little digging and see what I can find out.

On the INDU, can you possibly send me a screen shot? I am unable to duplicate this, but I would like to find out why you are seeing this.

It doesn't look like there were any oddball issues while I was gone, so hopefully there is an easy fix.

Data and Content Support » cbot mini metals died at 09:27a eastern Aug 4, 2008 04:24 PM (Total replies: 5)

Per CME Group, they will be resetting their eCBOT Market Update and Market Depth feeds at 16:40 CT this afternoon. This will eliminate the time stamp and sequence errors we are currently receiving on the eCBOT Metals contracts. These contracts normally close at 16:00 CT and reopen at 18:16 CT, so no downtime is expected.

We are currently confirming with the exchange if we can provide the full intraday metal history for today. I will let you know what we hear.

We are now working with the exchange to see how to best correct the data. There are two issues, the first being the lost data from earlier today. After transmission resumed, we were getting incorrect timestamps. It's a bit of a clean up process before missing data can be patched in. I will post again when I hear more on this issue.

Thank you for your patience,

Per CME Group, they continue to experience issues with the eCBOT Metals contracts.

DTN affected symbols include:

There is an ongoing problem with the feed we receive from CME. We are working with the exchange to get this resolved.

I have gone ahead and submitted a customer request for this feature, and agree that this would help all of us out! I will update when I hear back from our product management group.

Can you email me at with your login information? I am showing updates, so I will need to check what server you are on.

Data and Content Support » re: Eurodollar Jul 15, 2008 10:14 AM (Total replies: 4)

The @EU# is the futures symbol for the Euro dollar, however, I beleive you were asking for the actual index. We have the E.X (on NYBOT) and the EXY$Y (Euro Cash Spot Index, also NYBOT) which is also showing a price of around 123. I am digging to see if there are other indexes available, and will let you know if I find anything.

Data and Content Support » re: TNX & TYX Jul 14, 2008 12:21 PM (Total replies: 5)

Hi Tim,

I am looking at the TNX.XO and the TYX.XO in "raw" data format. The exchange send this data out in the 44.560 format, and if you are able to view it differently, this would be done within Amibroker. I am looking now to see if I can figure out the setting, though you may just want to contact Amibroker support.

Thank you for your patience,

I will be monitoring this closely over the next few sessions. Basically, if there is any delay between the exchange timestamp and the time the data was recieved in the feed, it will be logged. If you notice any specific timeframes where you experience lagging, please let me know, as this will help to narrow everything down.

We do appreciate your patience, and thank you again for bringing this to our attention.

Kind regards,

Good morning Allen,

The last split I am able to find evidence for is August 16th, 2006. Our Market Data group is looking into this now and will make any corrections as needed. We appreciate that you have taken the time to bring this to our attention. I will post here with our findings.

The following four major Dow Jones indices have been fixed internally in our Ticker & should now be updating properly:
