Attention!

Let's say the historical data manager is showing that I have ES 03-11 data for 2/9/11, 2/10/11, and 2/11/11, and I want to download data for that instrument from 2/01/11 to 2/28/11. If I enter 2/01/11 and 2/28/11 as the start and end dates in the Download tab of the historical data manager and then download data for that date range, will the data I already have (2/9 to 2/11) be re-downloaded, or will I only download data for the time I don't have? Thanks.

Hi Radical,

Thanks for your post - great question!

This data would be overwritten. One way to think of it is that the entire data set requested is downloaded.
