I have forgotten name of a trader who had very good methods back in the 1990's, he use to use TV ticker tape to find the highs after so much time and do a breakout of the S&P500 futures, he use to post I believe to "Club 3000" and he wrote a thin manuals for cheap costs cause he got tired of all the methods being sold for $3,000, once the manual was sold, guys in the pit caused protective stops to be hit on and off for over years time, so he wrote another manual to offer different entries and that one wasn't any better.
In 1989, Curtis Arnold made a method called "Pattern Probability System", selling it at $3,000, in 1993 he had it programmable and then he wrote a book in 1995 and masses had it and the pit would nail the protective stops. I believe the feds nailed him on some ballooned advertising, but the first few years, it was doing very well, I had even bought it.
I think very few get their edge in first few years, they gone through much mental anguish, financial losses, lose of time for family and themselves. Comes down to why hand others your edges as they not put in the effort or discovered for themselves, perhaps they refuse to learn how to program? If you have one or few golden gooses, keep it to yourself, and you won't have to compete and getting worst fills. You family comes first.
