I think it's easier to keep track of data if you don't download tons of it. I have a
fairly limited database compared to the people who run screens on 2,000 stocks a
night. FWIW - I don't optimize my systems either - except in a very broad sense (like
using 250 days instead of 50 days if I want a longer term system). Robyn
