Maybe in most cases either ego or cynicism tend to overweigh any desire for a quick buck (particularly for more experienced traders). If someone were to post a successful mechanical system, the egotistical traders will discount it because they feel that their respective methodologies are better, and the cynical traders will discount it based on the results of this poll. Plus, so many people post ideas on forums such as these (oftentimes with only anectodal evidence and no true hardcore backtesting), that it just becomes noise. Very rarely do I see someone post a detailed methodology along with any statistical backtesting results (including slippage, transaction costs, etc.) that truly back it up. However, if a trader were to say "I found a system that yielded a 75% success rate and averaged 3%/day net of slippage and txn costs over the last three years. Attached are the detailed steps and my historical results" I'll bet a ton of people would be all over it like flies on sh*t!
If they value the years of work, money lost, mental and physical stress that it took to develop a working system.. they wouldn't post it for free to a board of bickering fools.
