I won't say "winner" because that would imply that the contest is over and done and nothing more can change and that it is finished. It will never be finished - the quest is never ending - but we do have a modification to BOB that I'm going to adapt.
Bullish Jim discovered it and you will have to read about that
here and I suggest you read Jim's BLog frequently. There are two kinds of trading BLogs out there - those written by people who already know it all and wouldn't change a thing if their lives depended on it and those by people who actively seek change because they know growth only comes with change. Jim's is that kind of BLog - his is one of the good ones.
Anyway, long story short - Jim suggested that we constrain the first two candles to have a limited open to closing range. He did some tests and found some good results and I've followed up and my results are in this post.
I took my original BOB filter ("v1x")
show stocks where close is between 15 and 35
and average volume(90) > 500000
and ema(8) < ema(21)
and close 2 days ago < ema(8)
and close 2 days ago < open 2 days ago
and close 1 day ago < open 1 day ago
and low 1 day ago < low 2 days ago
and volume 1 day ago is more than 20% > volume 2 days ago
and close > open
and low > low 1 day ago
and made a change to it that I called "v31". ("v2" and mods are long gone).
and close 1 day ago is less than 1% < open 1 day ago
I then tested that version - we'll get to the results presently. Then I made a mod to "v31" named "v31x" -
and close 1 day ago is less than 1.5% < open 1 day ago
Followed by another test. Then I made an additional change (which is the change that Jim proposed) and I called this "v32" -
and close 1 day ago is less than 1% < open 1 day ago
and close 2 days ago is less than 1% < open 2 days ago
And tested that version. This was followed by one more change that I named "v32x" -
and close 1 day ago is less than 1% < open 1 day ago
and close 2 days ago is less than .5% < open 2 days ago
Notice that the difference is that the red bar two days back is constrained tighter than the red bar 1 day back. I tried it the other way around and achieved good win percentage but bad ROI. This way seems to work much better.
Here are the results -

And what now?
The tradeoff, of course, is that there is a variance in number of stocks selected as the filter becomes more constrained - here is how that looks -

You see that as the constraints become tighter you get a better return on the investment but the numbers of stocks selected goes way down. This is a dilemma - what to do, what to do?
Well here is what I'm going to do - I'm going to use every version and I'm going to access them daily in reverse order - "v32x" through "v1x" in turn and the first time I get a selection - that is going to be my BOB selection of the day.
Consequently I know that the risk is increasing as I progress through the filter set but we encounter risk all the time in this business. And the way we handle risk? Tighten up the stop.
Thank you Jim you are the Leader in the Clubhouse in the race to find the "better BOB".
CORRECTED:
And for any new readers - I use stockfetcher.com as my test bed. There may be better ones out there but this one is reasonably priced, allows me absolute freedom to write any strange method I can come up with and are really, really, really fast when responding to your plea for help via email.
