2 Things.

1. In March I put up a post about the speed of the backfill compared to Esignal and other sources. You acknowledged the issue and said it would be among top priorities to fix. Any progress?

2. More importantly.... In AmiBroker in addition to having a stock displayed in the main window you can build a scan which runs through a watchlist looking for a signal. I have managed to write some code that when run w/ IQFEED crashes AmiBroker. It does not Crash when I run the code w/ Esignal (which I'm trying to get rid of but so far you arn't making it easy...). I was running a trace routine and so far the only thing I can find is that at times while the scan is running (and sequentially filling or backfilling a series of tickers) and I click on the active window which causes this to refresh it's data - the two seperate requests for data (one from the scan and one from the main window) seem to get confused and I get information in the scan that should have been sent to the main window. I don't know if you can understand this but it is clearly some problem with how AmiBroker and IQFEED are pulling in data during a scan. I'm hoping you can talk to AmiBroker as I've sent them multiple messages to see if you can resolve the issue.

Mike,

I will see if we can work with Tomasz to figure out what may be going on.

As to the speed, we have a build of IQFeed in QA that should improve the speed depending upon how much data is being accessed. For pulling tick, or one minute data, the speed could improve by up to 70%. If only pull a few days of, say, 5 minute data, the increase won't be noticable. The speed difference is most noticable pulling tick data or pulling 1 minute data in large quantities. Hopefully we can get it fully tested in the next week or so and get it out the door.
