Hi HB,
Definitely not the same as UPI, but it is certainly risk-adjusted : )
That's a pretty nifty idea to rank that way assuming that you can effectively quantify the potential reward which, thinking out-loud, I suppose could be accomplished with some derivation of MFE.
Thanks for the post,

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.

Phsst, no you did not miss it because I never posted it.
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.

But all those QP2GetExtraData variables are not updated daily, so I don't think theywould be useful for a short-term trading system like I was talkingabout. Using PositionScore over a modest time period, you'd get thesame 4 stocks all the time, wouldn't you, or at least until they getupdated. Perhaps QRS gets updated weekly, so maybe that wouldn't be asbad, but I think I'd like something that is more reflective of thetrade system duration, in other words, something that I can updatedaily at EOD. > > > ----- Original Message ----- > From: Phsst > To: amibroker@xxxxxxxxxxxxxxx
