Hi HB –

 

Can you share with us your ideas for evaluating
potential reward and potential risk before the trade is entered?  When
using RR ratio, it is also valuable to have an idea of what the ratio of
winning trades to losing trades (WL ratio) will be.  Do you track RR and
WL on the fly and use these to filter potential trades?

 

Thanks,

Howard

Gary,





 





The reward-risk ratio is on a per signal basis.  Each
potential buy signal is ranked by its RR ratio.  





 





RR = potential reward for this trade / potential risk for
this trade





 





I don't think that's the same as UPI, right ?

HB,





 





Sounds like UPI or similar, yes?  They all seem to do about the
same.

My original one is based on a really simple reward/risk
ratio.  The higher the ratio, the better.





 





I'm also going to check out the suggestion of using system's
past performance on the stock.  That's how I regularly select my basket,
but I never thought of using it to rank.  This would be akin to what Chuck
& other have been saying all along.  I.e. don't select a basket, let
the ranking sort through all stocks and pick the good ones.

I looked and could not find where you posted your
favorite
Positionscore method. 

Did I miss it?

what are you basing your signals on
to give such short terms swings?  You can
keep in general if you like
(ie. ma-based, oscillator-based, etc.)

QP2 user also. But all those QP2
GetExtraData variables are not updated daily, so I
don't think they
would be useful for a short-term trading system

about. Using PositionScore over a modest time
period, you'd get the
same 4 stocks all the time, wouldn't you, or at
least until they get
updated. Perhaps QRS gets updated weekly, so maybe
that wouldn't be as
bad, but I think I'd like something that is more
reflective of the
trade system duration, in other words, something
that I can update
daily at EOD.
