"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
"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart
"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
"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip
"I "bracket trade" all major news releases and I have not found one lag or glitch with DTN.IQ feed. I am very comfortable with their feed under all typical news conditions (Fed releases, employment numbers, etc)." - Comment from Public Forum
"I am very pleased with the DTNIQ system for quotes and news." - Comment from Larry
"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe
"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
"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

Again, this is mostly directed at 3rd party developers - but everyone feel free to comment and offer criticism or recommendations.

Much like I discussed in Part 1 (http://forum.dtniq.com/index.cfm?page=topic&topicID=232) with Level 1 data, we've been noticing a marked increase in the requests for historical data, also. A lot of these requests are for the last minute, cycling through very large sets of symbols; all equities, for example - or a large portion of them.

1. Is the reason for this to eliminate the need to maintain historical data in your app, by just requesting it from our servers? If not, why the massive numbers of requests?

2. If there was functionality in IQFeed or the Level 1 servers to provide minute bars, would you use it?

3. We're currently working to add second resolution to historical data, as well as tick corrections. Is there any other functionality you would like to see in history retrieval?

We really want to try and make IQ and IQFeed the best products for our customers that we can, and your feedback helps us do that.

Total number of trades would be a useful additional data field.

There is no way to request the 1-minute bars for yesterday without also getting todays.

I would like to be able to watch a symbol on a per tick basis, 1 minute, ..., 1 month. I can implement this myself of course by tracking the ticks, but it would be better if it were done in the DTN machinery so that there is no error introduced by clock differences. What I am getting at is that I would like a bar given in realtime from a watch, or returned from the historic server to contain the exact same data.
