"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn
"I will tell others who want to go into trading that DTN ProphetX is an invaluable tool, I don't think anyone can trade without it..." - Comment from Luther
"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
"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
"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
"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
"If you want customer service that answers the phone, your best bet is IQFeed. I cannot stop praising them or their technical support. They are always there for you, and they are quick. I have used ****** too but the best value is IQFeed." - Comment from Public Forum

IQFeed Developer Support » Problem receiving historical tick data Mar 21, 2015 07:15 PM (Total replies: 1)

I'm able to receive real time tick data over a socket connection, but when i try to request historical data from 127.0.0.1:9100 ( i didn't change default port ) i just receive a network socket time out. My time out was set to 5 seconds. I tried a longer duration in case that wasn't enough time but no luck.

Any suggestions appreciated.

Thanks.

IQFeed Developer Support » Update messages over TCP/IP socket Mar 2, 2015 10:53 PM (Total replies: 2)

I have subscribed to receive a symbol over Level 1 TCP/IP and it's all working OK until i certain time where i seem to receive incomplete data. E.g. I receive 8 fields in the update message when i subscribed to 10.

When IQFeed sends an update message for a symbol should i expect all the fields that i subscribed to at once? Or could the update been broken up into multiple messages? I'm currently assuming all at once but i suspect that it's the later.

Thanks.
