"I had always used ******* but for the past 2 weeks have been trying DTN IQFeed. Customer support has been extraordinary. They call just to make sure your problem hasn't recurred." - Comment from Public Forum
"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
"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan
"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
"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat
"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
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat

It would be helpful if the FIGI id for a symbol was included in the mktsymbols_v2.zip file.

I've developed my own C# iqfeed client that I am considering productizing.

Yes I believe it was a socket error, but I'll run a quick test to verify.

IQFeed Developer Support » Historical Tick Data Request Hours Sep 11, 2018 12:00 PM (Total replies: 12)

Yeah I am storing it locally. I'll just have to do bulk downloads off hours.

One question though. Is there a way to change the timeout value for history requests? I cannot pull more than about three days worth of tick data before the connection closes. I suspect its timing related.

That's going to make backtesting/simulation difficult.

IQFeed Developer Support » Historical Tick Data Request Hours Sep 10, 2018 11:30 AM (Total replies: 12)

May I ask why this limitation exists? Also what defines trading hours? I'm working with futures and they trade around the clock.

Also is this noted in the documentation somewhere? I don't recall seeing it mentioned.

I was afraid you would say that :(

Calculating the end time is going to be tricky.

Can you guys clarify the documentation to indicate this isn't possible?

IQFeed Developer Support » Issue with HIT lookup message Aug 30, 2018 03:44 PM (Total replies: 3)

I am trying to get 10 bars of 5 minute history from a point in time forward, and I can't get it to work.

Here is my request and responses - I am specifying the begin date/time only:

I am specifying only a begin time and bar count. What I expect in return is:

I can only get it to work by specifying an end date/time of 2018-08-27 00:45:00 or by specifying both the begin date/time and end date/time.

My 'begin date/time only' request returns bars with timestamps starting at 16:35:00, which is the bar current at the time of the request (16:39:00)

What am I doing wrong?

Thanks,
-Jake

Isn't this information available with HDT/HDX lookup requests?


Hmm.

I tried request per socket again and it works fine. Not sure what I was doing different before.

Thanks!


Is it possible to make multiple history lookup requests at the same time? I can issue two requests, but the second one isn't processed until after the first. I've tried with multiple socket connections and no difference.
