Although you can speak freely "
Technical Analysis does not work, never did, never will"
I am sure there is some who makes profit with technical analysis.
However, most shows relatively low profit rate (at most 10%~20% compounded in the long run)
If one show about annual 20% compounded, such as Buffet, his wealth grows 9000 times over your entire life span, by 1.2^50 = 9100.438.
For example, if you save 10K at age 30 for future investment, yours should be 91000K=91M at age 80.
Since stock market were open for 400 years, his wealth is now 1.2^400 times, as long as he is alive for 400 years with annual 20% profit rate.
Probably there was almost NO one who attain the annual 20%. Tell me if there is.
I guess 15% might be rough idea for realistic suggestion by 1.15^50 = 1083.657, which implies 10K to become 10M over 50 years.
