Chuck,
You have filled things out somewhat, but I guess what I was asking
more specifically was:
1. What other kinds of qualifiers do you use to decide how to limit
the universe of stocks that you'll even consider some signal for
today ?
and ...
2. Does the system you use employ some sort of pattern matching
(Raschke's "grail" i.e ADX +/- DMI etc. plus a pullback etc. would be
an example of this sort of thing) or is it something that is more
trend of momentum oriented (MACD, Stochastic, Linear Regression would
be examples of this sort of thing)
TIA, Fred
