Hi, I'm having problems with the backfill and QuoteTracker. Both historical and intraday backfill appear to take a long time to fill. When I make a request to fill a chart, it appears to hang for about 3 to 5 min just for one symbol to backfill. The historical backfill seems to be slightly quicker but the intraday backfill is very slow. I'm having no problems with the streaming quotes.

I'm using:

QT Version: 3.9.1a-2
IQFeed version 4.4.0.3
WinXP machine SP3

Hello how many symbols are you looking at on your charts when you try to bring them up?? Also, how many studies do you have on those charts??

I am following 3 different symbols with 3 chart windows open. I have about 4 studies per chart. If I make 1 backfill request for only one chart, it hangs for a long time.

If I change the backfill to an alternate provder (i.e. - Prophet), it goes very fast (couple secs per symbol) but there appears to be a discrepancy in the backfill data received from Prophet and IQFeed's realtime data. I get a large spike in volume and weird volume amounts recorded.

If I set all my data sources to one provider like IQFeed, the discrepancies goes away but the backfill is slow with IQFeed. Again, I have no problems with the streaming Level 1 quotes by IQFeed. It's fast and smooth.

Is there anyway that you can contact us directly either by phone 1-800-397-7000 or by email at support@iqfeed.net, it may help if we can take a look this way rather than through the forums.

Thanks.

Curtis:

Quotetracker support helped me resolved this.
Here's the solution for other QT users who have the same problem.

Options
Data Sources/Proxy
Select Backfill tab
Uncheck "Get Tick Backfill Data" <----this is the culprit.

According to Quotetracker support, this item makes it a more quantitative process making the backfill slow.
