Looking at individual stocks.... I don't see the point of back-testing 1 or 5 or even 10 years back. All I want is a general idea of what is happening NOW. I'm looking at how a stock has acted over the previous 10 sessions and getting descent results going into the 11th day... Picking 10 days was arbitrary... all I knew was that I wanted to test a very short-term window... Does anybody look back very short term to get a general impression of how an individual stock is currently acting?
