Chances are the future won't work with these numbers.

I've been testing v1v2 from 1/1/2007 until 3/31/2007 and get the results I like. Then I run the same variables from 4/1/2007 until today and see if they hold up. The best variables in Q1 don't always work in the next period. So the best is to find something that works for a longer time period. For me a decent number has been bands of 20 with TP of 30, but I will publish more results later.
