Look like there are some outstanding people are nice enough to share some of their strategies, can you share who are these if you know some of them?
Acrary posted a divergence system on here that I was able to adapt and trade successfully for a few years. Mark Johnson (not sure if he posted here though) made some very useful contributions to my trend following systems. NoDoji's method of going through a chart by hand and logging the results also produces tradeable results. I also traded the Aberration system successfully for 6 years.
So 3 successful methods from the internet and one from a vendor after 16 years of trading (and none from books). However I have never traded somebody else's ideas without thoroughly backtesting them first. No shortcuts.
