"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George
"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro 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
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"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
"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei
"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
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email
"I used to have *******, but they are way more money for the same thing. I have had no probs with data from DTN since switching over." - Comment from Public Forum Post
"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

Hi,

I am running IQFeed on my windows PC, but I am writing a program to connect from a linux host through TCP socket. It seems to me IQFeed is only exposing the local loopback, 127.0.0.1 as the interface. Is that the case? I tried my PC's ip address, namely, 192.168.x.y, and I am sure the firewall is already open.

Can someone please confirm? So it is now intended to accept connections IPs other than 127.0.0.1?

Thx

Due to exchange restrictions against redistribution of data, we restrict IQConnect to only allow connections from 127.0.0.1.

It appears many are asking for this, including me, as many OSX and Linux programmers would prefer to write software on the platform we are familiar with.

I think a simple solution would be to allow the IP address to be configureable, but only one address, instead of hardcoding 127.0.01. So if one configures a different IP address, then local access is not possible anymore. This should be fine with the exchanges, since then the computer on which IQFeed is running would function just like a relay station, like a router or firewall.

Relaying the data from IQFeed on one machine to another machine would be considered redistribution.

The simple solution is to run IQFeed under WINE which will allow you to install and run it under OSX and/or Linux. Customers are doing this today without any impact to performance.

However, it isn't, after all that is what every router does. And others allow this as well, for the same exchanges. I'd like to encourage you to discuss this specific solution with your providers.

Do all the utility programs, which come with IQFeed, run under WINE (on Mac OSX) as well?

fwiw, I second the motion for a variable LAN IP. Many of the customers we're sending to IQFeed now run Wealth-Lab on two machines simultaneously.

Roberts, Unfortunately the policies from the exchanges haven't changed since the 2010 reply on this thread. It is considered redistribution of data if you move the data from IQFeed to a different machine. This is why we restrict access to the local machine and you would need 2 accounts and pay exchange fees twice if you use more than 1 machine. The exchange licenses allow the data to be used by a single person, on a single machine.
