"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 just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"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

IQFeed 5.2.0.9 is now available for all users on our download page at http://www.iqfeed.net. 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
