Quote from TFtrader:
It is amazing how many people fall into this trap of trading month after month. I have been back testing and forward testing numerous different trading systems and strategies for more than two years. My focus however was on index futures and currency futures. Spending more than 6,000 hours with analysis for this venture, I did not find anything that would nearly be reasonable to call a somewhat viable solution.
You definitively wasted you time because there is no way to get anything valuable that way except by pure luck.
All the work you did in 6,000 hours could be done by a computer in maybe a week, even less. How do you expect to compete with people who use data mining and genetic programming? It is like you try to compete in a car race with a horse.
