So I doubt that we would have a low risk trading that could result with double return, it would have to be something very risky. Whereas, if you aim at only 5% profit per month, which is HUGE on the long run, it still is far more likely.
I feel that will depend on one's trading capital for it to be that HUGE as you said. Take for instance, a 5% monthly profit for someone with a $1k trading account is just $50. Making $50 on a $1k trading capital in a month barely scratches the surface. I don't think anyone would be happy achieving that monthly.
This is why I try to keep it realistic, even 1-2% per month every month for over a decade would be a dream come true for me, yes some months are far better, but important thing is to average that much every month.
I dont know how realistic that will have to be, anyway; except that's on a passive income. On trading, that doesn't make any sense. Again, making that little monthly will suggest that the trader sorts their bills elsewhere, and don't rely on profit from trading. For those who're scared of taking risk, trading isn't for them; neither is this industry for them too.
