1.How many years/months did it take you to become a profitable trader?
In my guess, at least 5 or 10 years is necessary to say "I have profitable logic" for almost sure.
If you say, like Buffet, that over 45 years my profit was outperformed 12% over the index, then surely you are the winner.
Note that in the last 45 years the SnP500 index showed roughly 8%. Therfore 8+12=20% might be the best performance in the world, which compounded the initial seed to 4000 times, over the 45 years.
See the link at http://www.berkshirehathaway.com/letters/2014ltr.pdf
If there is better performance achieved than the 4000 times (roughly in one's life for 45 years), tell me now.
For a practical example, seed of 10K should be compounded to 4000*10K=40M (also initial 100K should go to 400M) for his entire life for 45 years.
