New tool for building multi stock time series data sets

Hi:

I have built a new tool that makes it easy to get multi-stock time series.

http://wikiposit.org/stockbuild

You select as many names as you want and then you can download a data set of daily, weekly, monthly, quarterly or annual closing prices for all the stocks in one clean data set. levels or % change. includes indices too.

feedback, comments, etc appreciated.

thanks
