"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim
"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"Its working FABULOUSLY for me!! Holy cow...there has been so much I've been missing lately, and with this feed and Linnsoft software...I'm in the game now." - Comment from Chris R.
"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.
"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
"I am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don

Starting today, lasting the whole day got screwed EUREX quotes for all products.

Please check timestamp... applies for bid/ask/last

Mixed timestamp order.

E.g. getting quote timestamps in this order:
1 08:00:11.xxx
2 08:00:15.xxx
3 08:00:12.xxx

Check e.g. symbol XGZ15.

Also a lot of missing quotes and trades too, today the feed was totally unrealiable. Wondering if a) I'm the only customer noticing this b) there is any monitoring on your side to check delivery of screwed quotes.

See attached a snapshot comparision between IB feed and your feed.
Looks like you edit EUREX timestamp-

Have a look at IB feed - 09:02:22 - Trade at 11048 with volume 4.
Your feed trades at 09:02:25

Why can't you just pass through the original EUREX data instead of obviously editing and somehow corrupting the data?

Our Engineers are looking into this. We have identified an issue on the servers that could be causing this. More to follow...

We have corrected the issue. It stemmed from changes that were made in our ticker plant to support the rollout of microsecond timestamps which will be coming to IQFeed in a future release. We will be reviewing this issue with our QA and development teams to understand how the issue wasn't identified prior to release and do everything we can to keep this type of issue from happening again.

Now getting one duplicate. See pic.

Two trades at 11108,5 with volume 2. Can tell it's a duplicate because the timestamp is in mixed order again.

Seems like this happened only once during the whole trading day, but you may want to have a look into it.
