"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

I'm having a problem retrieving historical data for options via TCP/IP. As a test, I picked 'MSQ FE' (Microsoft June call with nice volume) and issued the following commands:
HT,MSQ FE,5; HX,MSQ FE,100; HM,MSQ FE,1,5; HD,MSQ FE,5;
No matter which of the history commands I issue, the response is always a quick '!ENDMSG!'.
I've tried multiple symbols, etc but can't seem to get historical option data. Interestingly, the sample history applications IQFeed provides will retrieve data just fine (same symbol).
I'd gladly post source code that demonstrates the issue, but a simple telnet to 9100 will show the H commands return nothing. Help!

Ted,
Which version of IQFeed do you currently have installed? Do you have the 2.3 version? If so, we should be getting the new 2.3 out on Tuesday (after the holiday). We will see if that corrects your issue. Thanks

Note to developers using TCP/IP: The history server (9100) seems to not like spaces in symbol names. Given that this is the native IQFeed way to reference option symbols, this is a problem. A round of sniffing packets reveals that DTNHistoryLookup.dll replaces a space with an underscore prior to sending the request on to the history server. This is why I couldn't retrieve option data via TCP. Moral of the story: even though the rest if IQFeed references option symbols like this: "MSQ FE", you need to convert it to this "MSQ_FE" if you'd like to see history data. Can this subtlety please be placed in the documentation? Ted

Ted,
We are currently working on a fix for this, but we do not have a release date. Thanks for bringing this to our attention!

This issue should now be fixed. An underscore substitution should no longer be necessary in Option symbols.
