Hi Al !
For shorter-term signals, it seems like volatility is your best friend, and you'd mentioned that you've already tried that.
So, how about Fred's BollingerBand example:
BBandWid = 2;
UBBand = BBandTop(Close, 21, BBandWid);
LBBand = BBandBot(Close, 21, BBandWid);
PositionScore = 100 - 100 * (Close - LBBand) / (UBBand - LBBand);//0 when C == Upper Band, 100 when C == Lower Band
OR a variation of good 'ol RT
RT = Close / MA(Close,13); //64 bar is the original version
BTW, if you don't mind sharing 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.)
Kind Regards,
Gary

Thanks, Phsst. I'm a 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 like I was talking 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.

Al,My favorite is the QP2 QRS value (GetExtraData("QRS"). The QP2 QRSvalue is supposed to be a 'knockoff' of the IBD RS ranking score.I almost always get a significant boost using this ranking figure asas the positionscore.If you do not have QP2, but have any ideas about how to do your own RSRank calculation, I'd be happy to run some comparisons for you (oranyone else) to measure your calculated RS Rank against QP2's QRS rank.Cheers,Phsst--- In amibroker@xxxxxxxxxxxxxxx, "Al Venosa" <advenosa@xxxx> wrote:> Hi, all:> > I've been experimenting with variuos short term trading systemslately (average trade durations of about 2.5 days), and I was lookingfor ideas on how best to rank a watchlist to get the best candidatesfor portfolio trading a basket of 4 stocks.

your candidate list (using regular mode, notrotational mode). I've tried combinations of turnover and volatility,but I'd like to try other ideas. I'm not asking anyone to give awayany secrets, and, yes, I am aware of TJ's example in the help file(PositionScore = 100 -RSI());), but I was just looking for more ideas.I'm not even sure if this question is too vague or not. If it is, I'msure you'll tell me.
