"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.

Thanks for your response.

Here's my log file. I also had trouble connecting as you can see. It is always pretty slow, however last night was the slowest I've ever seen it. In the past (on 05/03/07), 1 day has taken from 8:34 to 9:15 PM just as an example. I do not run the same batch every night, I pull up a list of stocks based on criteria & run it when I have time that day (always after 7PM):

Hello. I downloaded 360 symbols, intraday tick data for 2 days last night. I started at 9:53 PM, and it didn't finish until 11:47 PM. Nothing was wrong w/my internet connection; it was fast. Any idea why downloading historical data is so slow?

IQFeed Developer Support » Backwards History Mar 12, 2007 08:10 PM (Total replies: 14)

I have resolved the backwards history issue (I haven't seen it since I re-wrote my code to use the historylookup2)...thanks again for your help.

I am still having issues w/connecting to the History Socket though. This happens almost every time I try to pull history on at least 1 symbol out of 200 or so. There doesn't seem to be a common time or symbol pattern...it appears to be random. I am using the new developer build.

Here's an example from my log today (EST time):

3/12/2007 7:17:11 PM Unable to connect to minute history socket
3/12/2007 7:17:21 PM download failed for BRCM

IQFeed Developer Wish List » Feature Requests Feb 20, 2007 11:08 PM (Total replies: 0)

Thanks for offering such a wonderful product & for taking the time to continue to improve it! It would be great to have the following features:

1. The ability to watch symbols in minute bar intervals (1,5,10,etc.) instead of having to compress the tick data from w/in my program.

Thanks!

So this is the IHistoryLookup2 then? And it will be supported in all future releases?

Thanks for your help....

IQFeed Developer Support » Backwards History Feb 2, 2007 04:01 PM (Total replies: 14)

How can I modify my app to use the newer interface? Is this a different method I need to call? That would be great until the new release comes out....

I really don't have a set time...it's usually anywhere from 5:30 EST to 1 AM EST. Are there certain times I should avoid?

I do have some logging in my app; here are some recent examples (EST Time) (my internet is connected at the time it can't connect to the history server, i can log in to IQFeed just fine..):

It seems like it happens when I'm having trouble connecting to the history socket....would that push me to a different server where I would get the older reversed data?

IQFeed Developer Support » Backwards History Feb 2, 2007 02:34 PM (Total replies: 14)

I run request every day after 4 PM for a certain set of stocks that meet my volume & price criteria. The list doesn't change that often since I'm dealing w/high volume stocks. It's always 1 min...not tick data or anything else.

It is the Beta version...

IQFeed Developer Support » Backwards History Feb 2, 2007 02:14 PM (Total replies: 14)

It's version 4.2.0.3.

I have an array of symbols. I loop though each & request the history. I wait until it's done w/one, then pause my app for 200 milliseconds (this seemed to help). Then, I call the next symbol & so on. It's usually about 153 symbols total.

Thanks for your response. I am using Build 865.7 from 12/21/06.

I declare the following:
Public WithEvents hlookup As DTNHISTORYLOOKUPLib.HistoryLookup

Then call:
hlookup.RequestMinuteHistory("AAPL", 1, 1)

Then I process the bar data in this event:
Private Sub hlookup_MinuteCompleted(ByVal lMinutesLoaded As Integer, ByVal aTime As Object, ByVal aOpen As Object, _
ByVal aClose As Object, ByVal aHigh As Object, ByVal aLow As Object, ByVal aVolume As Object, ByVal aIntVolume As Object) Handles hlookup.MinuteCompleted

Hello,

Once and a while when I pull data from the History socket it comes back reversed. My code is EXACTLY the same, this only happens maybe once a week. I've also been having trouble connecting lately, and receive the following error in my log file "Unable to connect to minute history socket". Below is an example of the reversed data - any idea why this is happening?:
