Quantitative modelling

[bigpooch]

The time horizons I am most interested in are 3 days to
3 months. On the other hand, it seems interesting to
consider all time horizons down to ten minutes but I don't
know if I can sit in front of my computer from the market
open to close (but I hear the smart money is either early
or the last hour before the close)!

It seems that for longer time horizons, nowadays you would
be considered "investing".
