It appears that we can only specify the number of days of backfill data we want...starting from the current day and working backwards. There are times when I have had problems downloading backfill data and didn't realize the data was bad until some number of days later. It would REALLY be nice if we had the option to request a date to retrieve backfill quotes for instead of having to go back and request possibly weeks of data just to get a day that needs to be redone from two weeks ago. Is this possible now? Could this be a reasonably simple feature enhancement? Thanks!

This functionality is not currently available. We will look into adding this for a future release of IQFeed.
