Hi, first post here (yes I did search for my question). I'm new to trading, but have been investing since I was in high school... I'd like to know if it is possible to use a stock screening tool, but apply the search query to a certain day in the past. For example, can I find all companies that had a P/E ratio between 5 and 8 on Jan 1, 2010. Or all companies that had a market cap of 100m to 200m on Feb 27, 2011. etc. I looked at a few demos, such as thinkorswim, and also google's stock screener, and they can only look at today's information, as far as I could figure out. Thanks in advance.
