"Version 4.0.0.2 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.

"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps
"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
"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate
"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'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
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"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
"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah

Hi,

If I use the demonstration IQfeed option chain program to return all option chains within 1 strike of the underlying for SPX.XO, it returns option chains correctly for the monthly options, but it fails to return the option chains correctly for the weekly options.

SPX1020K1140
SPX1020K1145

SPX1018L1140
SPX1018L1145

SPX1016J1140
SPX1016J1145

SPX1008J1140
<< there should be a SPX1008J1150 here, but its missing

SPX1001J1140
<< there should be a SPX1001J1150 here, but its missing

NOTE: I think the bug is related to the fact that there is no SPX1001J1145 for the weekly options, there is only a SPX1001J1150, and this may be screwing up the internal calculations somehow.
