Thank you for explaining but actually the question is not to get a direct answer that would be as you said " different". My question is a try to read what are the expectations in the minds of the traders when they figure out they have a profitable working strategy. However, i agreed with your answer that market should decide and not primarily on ones expectation.
From the poll, it is obvious that 10% or less is the ratio that most of traders thought it is a realistic profit percentage.
Don't get caught up in expectations. Most can only make what the market offers. In 08/09 the potentail was immense as the market collapsed and then soared. This year has been somewhat range bound. While I may be mocked for this, I trade not to lose and to beat MM rates. Doesn't sound like much but occasionally there's a huge year (or two).
Which market you are talking about? I think who play the same instrument but in a different time frame could consider him/herself playing different market? Does any here agree with me? Define market?
