So to answer your question, it will depend on your skills, your learning curve, your commissions structure and your commitment and dedication. Can you make 80%/year as a new trader? The answer is: most probably no. The conventional wisdom is that your goal as a new trader has to be not to lose money during your first year in trading. I know this is not what people want to hear, but that's the truth.
Can you make those returns after you learned the basics, learned the strategies and practiced them for few years? The answer is yes. We have many members who replicate and even exceed our performance numbers. But it took them years, not weeks or months to get there. Again, not what other services will tell you - but it's the truth.
