"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 was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email

"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip

"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton

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

"You have an excellent product !!!!!!" - Comment from Arely

"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

"I have been using IQFeed now for a few years in MultiCharts and I have zero complaints. Very, very rare to have any data hiccups or anything at all go wrong." - Comment from Public Forum

"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.

"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email

DTN_Gary_Stephen -DTN Guru- Posts: 394 Joined: Jul 3, 2019	Posted: Apr 25, 2023 01:35 PM Msg. 4 of 11 It looks like you're using version 6.1 of the IQFeed client software. This may be a bug that was fixed in 6.2: "Fixed bug causing IQFeed to occasionally try to authenticate an invalid product ID, resulting in customers getting an error stating their product or service is invalid." Is there a reason you're using the older version, or can you update the client software to 6.2 via http://www.iqfeed.net/index.cfm?displayaction=support§ion=download ?

DTN_Gary_Stephen -DTN Guru- Posts: 394 Joined: Jul 3, 2019	Posted: May 1, 2023 09:32 AM Msg. 7 of 11 LH will only appear if you are sending S,SET PROTOCOL 6.2 after you connect to the socket. You couldn't do this before, because you were on version 6.1 of the client software, and you can't request a later protocol than the client software. You must be sending some protocol command, though, because that response doesn't look the default 4.9, or even 6.1. Just change it to 6.2 and the response will match the documentation you found. "LH" is a Lookup Data Message Identifier as described at https://www.iqfeed.net/dev/upgrade.cfm?protocol=2 and is a new feature in Protocol 6.2.
