Not true padu, 1% is a very achievable daily return on account size, I do this frequently, with no leverage, today I exceeded that. The trick is being able to do this consistently with small drawdowns because it depends on how the market is behaving for your style of trading. I mentioned mo06's journal previously, this guy is knocking it out the park quite consistently, however going thru his journal, a couple of times he's been smacked so hard he's stopped trading at times for some months in order to recover his nerve I think. 5% for a week under good conditions is do-able, but you need a bit of luck on your side regarding the market smiling at you. Here's a journal entry of mo06 doing 5.23% for 2.5 days of trading.....CFD's I believe.
5 under par is achieved all the time by golf pros: I only played under par once in my life. so possible is possible just how difficult it is I know
