"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

"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've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"Can I get another account from you? I am tired of ******* going down so often" - Comment from George

"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George

"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah

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

"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

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

"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

Author	Topic: IQConnect suggestion (2 messages, Page 1 of 1)
mvo -Interested User- Posts: 8 Joined: Apr 8, 2009	Posted: Apr 14, 2009 10:09 AM Msg. 1 of 2 I'd like to suggest that DTN team considers stripping out calculation of "unnecessary" derived fields in IQConnect when user is not subscribing those with Dynamic Fieldset. This should substantially reduce IQConnect CPU utilization, especially during the fast market. Personally, I use only 1/8th of the total available fields, and none of them are calculated. Thanks, M.

In that version, we are evaluating having an option to only send a stream of trade and quotes and nothing else. Of course this means you won't get any cumulative volume, change or any other information that is derived from the stream. If we were to make this configurable, we would likely not save any CPU cycles as we would exchange "calculating data" for "checking to see if we should calculate data". Thus, it will likely be all or none. Jay Froscheiser DTN - Trading Markets
