"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom

"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum

"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

"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart

"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

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal

"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry

"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip

I set it to retrieve news every 1 mins and let it idle for around half an hour. After come back to it, I discover the news is not in order according to their id. You can refer to the attachment, those value of each news id is the number of repeated news received. I am curious why the news retrieved is random instead of order by id or datetime. Could you send me a documentation regarding to news API? Thank you. File Attached: Screenshot_7.png (downloaded 1160 times)

Are there any way to detect whether the news is for testing? or I can detect it whether have the same title or the story consists more than a number of 'TESTING' ? Please provide your opinion if you have better solution for this. Thank you.

Stories can belong to multiple news sources, this is probably the source of the duplicates you are seeing. As to the order of the return, I am not sure. I am guessing that we don't want to spend the time and/or processing power sorting the request so that you can get the data back that much faster. Documentation is located at the link below. http://www.iqfeed.net/dev/api/docs/NewsLookupviaTCPIP.cfm And no, different sources do different things when testing their datafeeds, but they do not send us any flag of what is real versus a test that we, or you, could trigger off of.
