Let's say that here in this forum someone created (after trial and error and a pretty long experience) the most consistently profitable filter/system.
Why not share it?
Someone would decide not to share it with others thinking that it would make it less effective or just because he/she doesn't want to share the fruits of his/her work and experience.
Someone else, more generous (and probably smarter) would, on the contrary, decide to share it.
Advantage:
Many more people would trade the same stocks selected through the very same filter/system and if we are going long, the more people would buy the same stock I am buying and make it "go up" faster and more steadily and therefore the more my system/filter is shared and the more people use it to trade and the more the results of the filter will be profitable.
Unless some here secretly are institutional fundmanagers I think the filter would need to include something like 'average volume(90) below 20000' to make a noticable impact on the market.
I share almost everything I develop here on SF. To your point, posting winning systems here does not threaten future returns, especially when you are looking at highly liquid stocks or ETFs - if every single SF user traded the same AAPL, SPY, or AMZN system at the same time it would likely not move the spread by even a penny. Any stock which trades over a million shares a day would not even feel the slightest impact from SF users.
Recently I have not been doing it quite as much - not because I am greedy, but because I get pelted with questions on the code, people always try to alter it to make it "better" without testing it, and there is always one or two folks who just enjoy trolling. After a while it is just easier to focus on my own trading and assume others will do the same.
Yes, I noticed that you have been and are most likely the one who has been sharing the most here in SF, and that is a great virtue of yours for which you should be admired, besides respected.
At the same time it is understandable your feeling of being turned off by the behavior of a few, even though i am sure that the great majority of SF members misses your experienced input.
With all the years of experience you have, what would be your latest, and one and only best filter recommendation you would share on the Filter Exchange section?

Thoughts by Ed Seykota on "THE TREND"
https://www.tradingwithrayner.com/39-things-said-by-the-greatest-trend-follower-of-our-time-ed-seykota/
I use Stratasearch to develop my trading systems - note that I say SYSTEMS and not FILTERS. A filter is useless if it does not tell you when to exit a trade. This is where I see the greatest challenge for SF folks - they only care about the entry and never stick religiously to an exit criteria as part of their trading decisions.
I also build systems that are based on 5 - 10 different entry/exit filter combinations. I allocate my trading capital among them, making sure that each uses a different entry criterion. Most are 80-90% win rates but trade infrequently. However, when combining them you can better utilize your trading funds with more entries and exits than any one system can provide.
I shared a strategy that has consistently worked for me here:

All you need to do is go to the sharedlist page and check whether I updated "filter". If so, run the fetcher from the thread, choose your pick and sell an out of the money put 4 to 6 weeks out.
Thank you Mahkoh, but now you are talking about Options that can be tricky because you can "win" small several times but when you do "lose" you lose big...
