I would be interested in getting a Meta formula language thread going, I'd even be happy to administer it (I also use OmniTrader, but don't see much value in it having it's own thread bar for various models that people have built as well as daily picks and commentaries).
Personally, I think that people get way too caught up in filters and the like, and for some users, having a large collection of filters is akin to stamp collecting.
The fact of the matter is that there will never be one singular 'super filter' that works under all trading conditions. If traders educate themselves to understand the various market characters and environments along with leading / lagging, oscillator and trend based indicators, they would rether quickly understand that 3 or 4 filters do the trick in terms of identifying condusive trading opportunities.
In the near future, I will start posting charts to show you what I mean, but for the moment, it's something to think about!
