@guru, fascinating thread and a great read. The Holy Grail means different things to different people. Would you consider yourself to have found it, if it meets the following criteria?
1) You can make 50%+ profit a year, year after year, regardless of market conditions.
2) The system can withstand 2008/09, the Feb 2018, Dec 2018, and Mar 2020 crashes.
3) The strategy is scalable (say, up to a $5million account or more).
4) You do not have to be glued to the screen 7-8 hours a day.
Happy trading.


Doesn't this show that the market is efficient. For a capable programmer who builds such a system, he should make around 200K to 300K in the US being employed by mega corp.
