"I just wanted to let u know that your data feed/service is by far the best!!! Your unfiltered tick data is excellent for reading order flow and none of your competitors delivers this quality of data!" - Comment from Peter via Email
"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
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"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
"I was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email
"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email
"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email
"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton
"I had always used ******* but for the past 2 weeks have been trying DTN IQFeed. Customer support has been extraordinary. They call just to make sure your problem hasn't recurred." - Comment from Public Forum
"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'm using QuoteTracker and several times each morning my IQFeed feed will stop getting data or will lag badly behind InteractiveBroker's data. I think it's IQFeed and not IB's problem because none of my charts update and I'm able to execute trades at the displayed NBBO on IB which may be 0.10 or 0.20 away from what IQFeed is showing (on a $25 stock like LVS).

I experience the same thing when using custom applications so I don't think this is a QuoteTracker bug. My system stats show 60% Memory usage and none of my 4 cores show more than 70% usage so it's probably not a hardware issue (and, as I've said, IB is still updating).

Is there a way of fixing or tracking down this problem?

Sounds unusual. I use SierraChart and never had any problems (tick charts of @ES, @NQ, @YM, USO, UNG, COMPX.X, INDU.X, SPX.XO, TICK.Z) . IQFeed and TWS go hand in hand, news events included. There might be an occasional discrepancy one way or the other, but nothing serious (in sub-second range).

I'm subscribed to 200-300 symbols and they all stop at the same time, several times each morning, for 3-15 seconds at a time. Nerve wracking for scalpers like me.

adrian, it sounds like you might be short on resources somewhere (CPU/RAM/Bandwidth/etc)...

Our customer service department should be able to help you identify the issue if you contact them via phone or chat.
