I have looked at systems of this nature. My overall impression is that they show you past momentum and current highs, with low probability of similar future performance. If you trade the top picks from the list, they have a high probability of being at their highs, and will reverse and cost you $. Beware.

Did you look at the backtesting I posted on the first page? While I don't disagree with your opinion, I prefer to rely on results.
How well will this particular filter do in the coming months? I'm not sure. But I think that it has shown over the past 52 weeks to produce a very decent return, even during periods of extreme volatility in the markets.

Sure these stocks can reverse at some point - but I like the idea of trying to jump on a well-established trend better than trying to pick a reversal. But it is a good point - any other variable we can add to avoid buying at extreme highs or lows? Maybe outside of a big upper or lower BB?

A slightly modified version - here I have only looked back 8 weeks instead of 13. The goal here is to look at just the last two months of performance, and not allow older data to drive the stock selection process
This yields only three stocks for the coming week: PWER, YMI, and NANO.
Good luck.

I back tested it for a 5% profit target and and maximum 5 holding days. ROI: -264% (that's a minus)

Not to put too fine a point on this, but you are incorrect. If you use the offset function and go back 1 year ago last Friday, you will get a list of several stocks. Pick the top score (in case of a tie in the reward score, use the highest performance score to choose). Now advance forward to the next week for those specific stocks and see how they have done. Record performance.
Repeat for each week. Every week needs to be done this way to get accurate data.
If you do this you see that the performance I posted in the first post of this thread is correct. If you don't want to, that's fine as well. Simply do not trade off of the results from this filter.

Kev - here's my ideas to the long version (have the short as well if you're interested). Main thing I wanted to accomplish was to weight the "near term" weeks separately than the "prior term" weeks to avoid putting extra weight on the near term. In this case, the last 5 weeks gets 45%, and the previous 10 weeks gets 55% (totally arbitrary weights).
After some more tweaking - at some point I'll try doing some informal backtesting like you said...a lot of work! Btw, the screening output only works correctly if it's run on weekends, right? How do I do date offsets to go back that far in time, and how can you tell what day the results are from? We want them to always be from previous Friday's closes, correct?

PWER, YMI and NANO all hit their 5% target for the week.
Only 4 picks for this next week - in descending order, they are:
PWER
performance - perfect hit for the last 8 weeks
reward 3.00
YMI
performance 12.00
reward 3.00
NANO
performance 2.18
reward 3.00
GGWPQ
performance 11.50
reward 2.88

Kevin-
Your manual back test suggestion requires a lot of work. Are you saying SF's back test feature does not work correctly?
