An expert trader doesn't mean that they made 10 % per day or so , an expert trader mean 1-2% per day but months or years of consistency like that
That is not an expert trader then, it is more of a coward trader that doesn't have the guts to risk even if he knows that he/she can beat the market. Yes, you can get a steady profit but where is the fun in that, are you really alright with just getting 2% when there are opportunities that you could have get a 10 or a higher percent. I would say that an expert trader is not someone that only has a consistent performance but someone that also sees the opportunity as to when will he/she get a big profit, so in essence, an expert trader should be a mixture of opportunist, smart, and consistent.
