"You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email

"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat

"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

"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

"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

"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps

"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom

"I am a hedge fund manager here. It’s funny, I have a Bloomberg terminal and a Bridge feed, but I still like having my DTN feed!" - Comment from Feras

wmillows -DTN Evangelist- Posts: 116 Joined: Jul 14, 2004	Posted: May 23, 2007 03:52 PM Msg. 5 of 18 I tried VIX last night. The option chain I got has May 07 series and no July 07 series. I couldn't confirm it (I am at work) at this moment. Could you double check if the option chain has latest series issued by exchange?
DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: May 23, 2007 05:37 PM Msg. 6 of 18 Right now, I am gettin the same data from an Option chain lookup on Pre as I do on our production servers. However, SSO would be a symbol lookup (not an option chain lookup). I can confirm that there is a difference between the results returned here but I will need to do some more digging before I can find the cause.
wmillows -DTN Evangelist- Posts: 116 Joined: Jul 14, 2004	Posted: May 27, 2007 05:22 PM Msg. 7 of 18 Hi Steve, I am aware of the difference. I use SSO because it is based on simple string matching, my program will filter out the correct series. Where as with OEA, I found out sometimes it could miss option chains, especially, if an underlying has multiple roots. I've been using SSO as option chain lookup for 4 years, it is simple and has less dependencies on server logic. Could you double check OEA command on new pre-production server? It seems new pre-production server returns only near money option series.
DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: May 29, 2007 03:31 PM Msg. 8 of 18 I am still not noticing any differences between the production and pre-production servers for the OEA command. There are a few differences when using the OFO as well as the SSO commands but as far as I can tell this is due to the Pre-Production servers still having some expired contracts returned (the Pre servers are returning more data than the production servers). Can you give me an example of the output where you are seeing discrepancies?

wmillows -DTN Evangelist- Posts: 116 Joined: Jul 14, 2004	Posted: May 31, 2007 01:35 AM Msg. 11 of 18 Hi Steve, I tried to download option chains from new server, but IQFeed client crashed before it can finish. With few underlyings that finished, I found CUB is missing strike 30. BCO doesn't have LK/XK. Could you check, thx.

DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: Jun 7, 2007 01:46 PM Msg. 14 of 18 This is not yet fixed. I believe the server team has identified what is causing the problem but have not yet gotten a fix implemented.
DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: Jun 8, 2007 09:14 AM Msg. 15 of 18 This should be resolved. Let me know if you still see any problems.

DTN_Steve_S -DTN Guru- Posts: 2093 Joined: Nov 21, 2005	Posted: Jun 11, 2007 10:30 AM Msg. 17 of 18 The expired contracts is an issue that should be isolated to running in the pre-production environment and should not be an issue once this is rolled out onto the production servers. We will do some more testing with this to verify this is the case.
