"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
"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post
"Version has been working well for me and I appreciate that it is now a much tighter client to work with. I feel I can go to press with my own application and rely on a stable platform" - Comment from David in IA.
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"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
"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John
"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
"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
"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

IQFeed is now available for all users on our download page at The IQFeed development team has spent quite a bit of time working to improve the connection logic and make IQFeed overall more efficient and reliable. In addition, we also now support Millisecond timestamps from the exchanges in which we receive it. IQFeed is now faster, more precise and just better in every way!

1. Stability – There was extensive work done in this release to fix crashes and hangs in IQFeed 5.1. These fixes were especially focused around the connection/disconnection/re-connection logic when internet outages occur.
2. Microseconds – time precision down to 1µs for any exchange that provides it to us.
3. Speed – In our internal benchmarks for IQFeed 5.2, it delivers Level 1 data quicker than 5.1 (of course, we are talking microseconds of improvement since 5.1 was already pretty speedy).
4. Leaner – IQFeed 5.2 uses less memory than 5.1
