"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum
"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

"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger

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.
