"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 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
"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"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
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post

"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 used to have *******, but they are way more money for the same thing. I have had no probs with data from DTN since switching over." - Comment from Public Forum Post
"It’s so nice to be working with real professionals!" - Comment from Len

Suggestion is following: Raise an event in case when no data available for the requested interval. Now my calling thread is sleeping up to timeout (20 seconds - 1 minute for me). It would be great if the event would inform about it immediately. It is very important for my application.

Many thanks for your consideration.

Can you give me an example of the request you are making?

HistoryLookupClass.RequestMinuteHistory("MSFT", 1, 1);
The situation reproduces if I'm doing such request on Monday morning (or holidays...), because there is no historical data.

What you are requesting is actually the intended functionality of IQFeed.

You are experiencing a bug that is specific to the HistoryLookup interface. It does not exist in the HistoryLookup2 interface or in the sockets interface.

I'm not experiencing a bug, I'm offering you to enhance it a bit so that the AbortLoad event needs to be raised in some additional case, or MinuteProgress event brings 0 bars loaded in its event args in case if there is no data on the requested interval. This does not require the changes in the interface.

I never said that it required changes to the interface. I simply said that this interface is the only interface affected.

The fact that the request takes a LONG time to return an error in the given scenario, IS the bug. It is due to a combonation of factors involving the communication with the servers. It will be fixed in an upcomming release of IQFeed.
