Preparing the StoRsi for QQQ Formula For Trading as a System

["dingo" <dingo@xxxx>]

Thanks toSteve 
Karnish we've had a lot of discussion about developing a formula (see below) 
that might be appropriate for actual use. I say "might" because (no slight to 
Steve here) I'm not certain that I know how to determine that this formula would 
make a good basis for a system.  That's where I think we should aim our 
next discussion..

So, let me ask the 
people who've actually used formula in systems and traded with 
them:
<SPAN

Is the formula below 
a good basis for a system? Please explain why and how you came to your 
conclusions!

What would YOU do to 
improve it or is it just not ready for prime time?

I really think that 
this would help a lot of us that are new to the "game" understand more about the 
development process and prevent some of us from just jumping off the deep end 
and potentially loosing a lot of money.

BTW - I've been 
thinking about taking some of the discussion about Steve's formula and putting 
it into a document as and example of how one might go about doing this. Sort of 
an extended tutorial. Any comments on that?
